Commercial Transactions (M&A)

Introduction to Commercial Transactions

Deal Structure Overview

A commercial transaction involving the transfer of a business, or control of a business, can be structured in a number of fundamentally different ways. The choice of structure shapes every subsequent aspect of the deal — including tax treatment, liability exposure, the need for third-party consents, and the regulatory approvals required before closing. The principal deal structures in Canadian M&A practice are:

The precise definitions of the terms "merger," "acquisition," "take-over," and "amalgamation" are found in various statutes governing the specialized field. However, definitions vary considerably across statutes and common law, and the parties to a transaction are entitled to redefine these terms contractually to suit their particular structure. This flexibility is a source of both opportunity and complexity — parties and their counsel must be deliberate about which legal framework governs each step of the deal.

The Transaction Cycle

While no two transactions are identical, a typical M&A transaction in Ontario proceeds through a recognized sequence of stages. Understanding this cycle is important for managing timelines, allocating risk, and knowing which legal instruments are operative at each point:

1. Mandate and Preliminary Assessment — The parties identify one another (through a market process, proprietary contact, or intermediary), and counsel conducts a preliminary assessment of structure, regulatory exposure, and transaction feasibility.
2. Letter of Intent or Term Sheet — The key commercial terms are recorded in a non-binding (or partially binding) LOI, including price, structure, exclusivity, and timeline. Provisions regarding confidentiality and break fees are typically binding even where the LOI itself is not.
3. Due Diligence — The buyer conducts a structured review of the target's legal, financial, tax, employment, environmental, and operational position. Findings inform the representations and warranties, conditions to closing, and purchase price adjustments in the definitive agreement.
4. Negotiation and Execution of the Definitive Agreement — The parties negotiate and execute the share purchase agreement, asset purchase agreement, amalgamation agreement, or arrangement agreement, along with ancillary documents such as disclosure schedules, transitional services agreements, and employment arrangements.
5. Regulatory and Third-Party Approvals — Where applicable, the parties obtain required approvals from the Competition Bureau, Investment Canada, industry regulators, and third parties whose consent is required under material contracts.
6. Closing — Consideration is exchanged, title to the shares or assets is transferred, and closing deliveries are completed. In a share deal, this includes the delivery of share certificates or a direct registration entry; in an asset deal, individual assignments of assets and assumption of liabilities.
7. Post-Closing — Transition, integration, post-closing adjustments, and any indemnity claims under the purchase agreement are addressed in the period following closing.

Governing Legislation

Commercial transactions in Ontario are governed by a web of federal and provincial legislation, and parties and counsel must consider which statutes apply to each element of the deal:

• The Canada Business Corporations Act, R.S.C. 1985, c. C-44 ("CBCA") — governs federally incorporated companies including amalgamation, arrangements, and compulsory acquisitions;
• The Business Corporations Act, R.S.O. 1990, c. B.16 ("OBCA") — the provincial equivalent for Ontario-incorporated corporations;
• The Competition Act, R.S.C. 1985, c. C-34 — governs merger review, pre-notification, and anti-competitive effects;
• The Investment Canada Act, R.S.C. 1985, c. 28 (1st Supp.) — governs foreign investment review and national security screening;
• The Income Tax Act, R.S.C. 1985, c. 1 (5th Supp.) — central to deal structuring, particularly the distinction between share and asset transactions, rollovers under s. 85, and the amalgamation rules under s. 87;
• The Excise Tax Act — governs HST/GST obligations arising on asset transfers, including the s. 167 election;
• Ontario's Securities Act, R.S.O. 1990, c. S.5 — applies to reporting issuers, take-over bids, and going-private transactions;
• The Personal Property Security Act, R.S.O. 1990, c. P.10 — relevant to security interests over personal property in asset deals; and
• The Employment Standards Act, 2000, S.O. 2000, c. 41 — governs continuity of employment obligations on the sale of a business.

Share Acquisitions

What the Buyer Acquires

In a share acquisition, the buyer acquires the shares of the target corporation directly from the selling shareholders. Because the target's legal identity remains unchanged, the buyer indirectly acquires everything the target owns — its assets, contracts, permits, licences, employees, and liabilities — as well as everything the target owes. The acquisition of shares in a limited company does not make the purchaser a new owner of the corporate assets in the direct sense; rather, the buyer steps into the shoes of the prior shareholders and assumes the same relationship to the corporate entity as they had.

The legal consequence is significant: a buyer in a share deal assumes all of the target's liabilities, including undisclosed, contingent, and historical liabilities. This is the defining risk of a share purchase, and it explains why thorough due diligence and well-drafted representations, warranties, and indemnities are not merely desirable but essential.

Advantages and Disadvantages

For sellers, a share sale is almost always preferred. The proceeds are typically taxed as a capital gain rather than ordinary income, and where the target is a Canadian-controlled private corporation ("CCPC"), the seller may be able to claim the lifetime capital gains exemption — which shelters a significant amount of gain per individual shareholder. A share sale also achieves a clean exit: once the shares are transferred, the seller has no ongoing relationship with the target's contracts, employees, or liabilities, unless they have provided personal indemnities under the purchase agreement.

For buyers, a share deal carries the risk of inheriting all of the target's liabilities — including those unknown at the time of closing. Buyers mitigate this through due diligence, representations and warranties, indemnification provisions, and, increasingly, representations and warranties insurance ("RWI"). The buyer also does not obtain a step-up in the cost base of the target's underlying assets, which means less depreciation over the life of the investment compared to an asset deal. These disadvantages often result in a lower purchase price in share transactions relative to asset transactions — a price discount that reflects the buyer's additional risk.

Compulsory Acquisition

Where a buyer acquires the shares of a public company through a formal take-over bid, both the CBCA and OBCA provide a mechanism for compulsory acquisition of the remaining minority shares. If the buyer acquires ninety percent or more of the shares that were subject to the bid, it may give notice to the remaining shareholders requiring them to sell their shares at the same price paid under the bid. This mechanism, sometimes called a "squeeze-out" or "going-dark" acquisition, eliminates minority shareholders after a successful majority bid. Minority shareholders have a corresponding right to demand to be bought out at a fair price.

Shareholder Agreements

In privately held corporations, the relationship among shareholders, and the mechanism for transferring shares, is typically governed by a shareholders' agreement rather than corporate statutes alone. Counsel acting on a share purchase of a private company must identify and review all existing shareholder agreements and their effect on the contemplated sale. A shareholder may have standing to sue or act on the basis of a contract rather than statute where the corporation is bound by a unanimous shareholders' or pooling agreement.

Key provisions in shareholders' agreements that affect deal mechanics include:

• Rights of first refusal — requiring a selling shareholder to offer the shares to existing shareholders before selling to a third party;
• Buy-sell (shotgun) clauses — permitting one shareholder to set a price and require the other either to buy at that price or sell at that price. The buy-sell clause has been judicially described as powerful in its effect; parties must comply precisely, with clear intent and unconditionally;
• Drag-along rights — allowing a controlling shareholder to compel minority shareholders to join in a sale on the same terms;
• Tag-along rights — giving minority shareholders the right to participate in a sale by the majority on the same terms;
• Transfer restrictions — limiting the ability to transfer shares without board or shareholder consent;
• Consent requirements — requiring unanimous shareholder approval for certain transactions, including the sale of all or substantially all of the corporation's assets.

Asset Acquisitions

What is Acquired

In an asset acquisition, the buyer acquires specific assets of the target business — which may include tangible assets (equipment, inventory, real property), intangible assets (intellectual property, customer lists, goodwill), and specific contractual rights — together with any liabilities the buyer expressly agrees to assume. The seller retains the corporate entity and all assets and liabilities not included in the purchase.

Asset deals require a comprehensive schedule of acquired assets and assumed liabilities, because only what is specifically listed transfers. Buyers must ensure the asset schedule captures every asset necessary to operate the business as a going concern — including not just obvious physical assets but also licences, software, permits, data, and domain names. Any asset omitted from the schedule remains with the seller.

Assumed and Excluded Liabilities

One of the principal advantages of an asset deal for the buyer is the ability to select which liabilities to assume. Typically, a buyer in an asset transaction will assume trade payables arising in the ordinary course, obligations under assigned contracts, and employee entitlements arising after closing. The seller retains pre-closing tax liabilities, litigation claims, and environmental obligations unless specifically assumed by the buyer.

However, this advantage is qualified in several important respects:

• Employment law — Under Ontario's Employment Standards Act, 2000, where a business is sold as a going concern, the buyer is deemed to be a continuation of the seller for purposes of minimum statutory entitlements, and employees' prior service counts against the buyer for ESA obligations such as notice of termination;
• Environmental liability — Ontario's Environmental Protection Act can impose liability on a new owner of property for pre-existing environmental contamination regardless of contractual exclusions;
• Successor liability — In some circumstances courts and statutes impose liability on a successor to a business even in asset deals, particularly for product liability, pension obligations, and CRA deemed trust remittances.

Third-Party Consents and Assignment

In an asset deal, the buyer does not step into the shoes of the seller by operation of law — each contract must be assigned individually, and most commercial contracts require the consent of the counterparty to any assignment. Where consent is withheld or cannot be obtained, the contract cannot be transferred, which may significantly affect the value of the transaction. Key contracts requiring assignment analysis include:

• Customer agreements (particularly long-term contracts and supply agreements);
• Licences for key intellectual property, including software;
• Leases of real property and equipment;
• Financing and credit facilities (which typically prohibit asset sales without lender consent); and
• Regulatory licences and permits issued to the selling entity personally.

Counsel conducting due diligence must review every material contract for assignment provisions and change-of-control triggers, and the parties must build a consent strategy into the transaction timeline — identifying which consents are conditions to closing and which may be deferred.

GST/HST: Section 167 Election

The transfer of a business as a going concern in an asset purchase is generally subject to HST on the purchase price under the Excise Tax Act. However, the parties may jointly elect under section 167 of the Excise Tax Act to treat the transaction as a transfer of a going concern, eliminating the requirement to collect and remit HST on the purchase price. The section 167 election requires that:

• The supply constitutes the transfer of all or substantially all of the property reasonably regarded as necessary to carry on the business;
• The buyer is acquiring the business for the purpose of continuing to supply taxable goods or services; and
• A joint election in the prescribed form is filed with the Canada Revenue Agency.

The election is significant in deals involving substantial consideration — it prevents the buyer from having to fund an upfront HST payment (which would otherwise be recoverable as an input tax credit, but creates a temporary cash flow burden) and eliminates the administrative complexity of HST remittance and recovery on the sale of business assets. The election is unavailable in respect of supplies of real property, which remain subject to GST/HST under their own regime.

Amalgamations and Arrangements

Statutory Amalgamation

An amalgamation is the statutory process by which two or more corporations merge to form one successor corporation, which inherits all of the property, rights, liabilities, and obligations of the predecessor corporations. Unlike a share purchase (where the target continues to exist) or an asset purchase (where assets are individually transferred), an amalgamation effects a complete fusion of the combining entities at law.

The classic description of an amalgamation is the "rolling of two concerns into one" — the amalgamated company becomes capable immediately of exercising the functions of an incorporated company, and the property, rights and interests of each amalgamating corporation continue in the surviving entity. The amalgamated corporation is simultaneously liable for all the obligations of each predecessor corporation.

Under the Income Tax Act, s. 87 provides that an amalgamation results in a new corporation, which is treated as a continuation of the predecessor corporations for tax purposes. Where the predecessor corporations were both taxable Canadian corporations, the amalgamation is generally tax-deferred — shares of predecessor corporations are exchanged for shares of the amalgamated corporation without triggering a disposition. This tax treatment makes amalgamation an attractive tool in corporate reorganizations and post-acquisition integration.

The CBCA and OBCA distinguish between a long-form amalgamation (requiring shareholder approval by special resolution) and a short-form vertical amalgamation (permissible between a parent and its wholly owned subsidiary without shareholder approval, other than the board resolution of each company). Short-form amalgamations are widely used in M&A transactions to roll the target into the buyer's corporate group following a share acquisition.

Plans of Arrangement

A plan of arrangement is a court-supervised process under the CBCA (s. 192) or OBCA (s. 182) that enables transactions too complex to be completed through ordinary share or asset purchase mechanics. Plans of arrangement are commonly used for public company acquisitions, complex restructurings, and transactions requiring multiple steps such as share exchanges, reclassifications, or concurrent M&A and financing transactions.

The process involves an application to the court for an interim order authorizing the calling of a special meeting of shareholders (and, where affected, creditors), followed by a vote at the meeting and a final order approving the arrangement. The court assesses whether the arrangement is fair and reasonable to those affected and has been approved by the requisite majority. A plan of arrangement that has been court-sanctioned is binding on all persons — including dissenting shareholders — and courts have confirmed that the finality of a sanctioned plan cannot be challenged by collateral attack after the fact.

Legal Effects of Amalgamation

Several specific consequences of amalgamation frequently arise in practice and require early planning:

• Successor liability — Claimants against a predecessor corporation may bring their claims against the amalgamated successor. Contract clauses providing for joint and several responsibility of successors are common in settlement agreements and regulatory undertakings;
• Dissolution of subsidiary on vertical amalgamation — A short-form vertical amalgamation causes the subsidiary to cease to exist, and its assets and liabilities merge with those of the parent. This requires attention to any agreements, licences, or registrations in the name of the subsidiary;
• Land title — Under Ontario's Land Titles Act, amalgamation constitutes a change of name for the purpose of registering title in the name of the amalgamated corporation. The registrar may endorse the change on the register, avoiding the need for a formal transfer of registered title.

Due Diligence

Purpose and Scope

Due diligence is the structured process by which the buyer (and sometimes the seller) investigates the target business before committing to close. Its purpose is to verify the accuracy of the seller's representations, identify undisclosed liabilities and risks, inform the negotiation of representations and warranties, and assess whether the transaction is viable at the proposed price and on the proposed terms. A failure to conduct adequate due diligence does not eliminate the buyer's exposure to undisclosed liabilities in a share deal — it merely means the buyer has no informed basis to negotiate protections.

Due diligence is typically conducted through a virtual data room (VDR) in which the seller populates folders corresponding to each due diligence category. The buyer's legal, financial, tax, and operational advisors review the materials, raise written questions, and summarize findings in a due diligence report that identifies issues requiring negotiation or further disclosure. The report then informs the preparation of disclosure schedules that qualify the seller's representations under the purchase agreement.

Legal Due Diligence

Legal due diligence typically covers the following categories:

• Corporate records — Verification of corporate status, minute books, share registers, and authorizing resolutions. Counsel confirms that the shares being sold are validly issued and outstanding, and that there are no undisclosed options, warrants, or pre-emptive rights;
• Material contracts — Review of all significant customer, supplier, licence, employment, and joint venture agreements for assignment restrictions, change-of-control triggers, termination rights, and unusual obligations;
• Real property — Title searches and review of leases, encumbrances, surveys, and zoning compliance for all material real estate;
• Intellectual property — Review of IP registrations (trademarks, patents, copyright), ownership chain, licence-in and licence-out arrangements, and any IP challenges or disputes;
• Litigation — Review of all pending, threatened, and potential claims. In a share deal, all litigation attaches to the buyer; in an asset deal, specific claims must be assumed or left with the seller;
• Regulatory compliance — Review of licences, permits, regulatory filings, and compliance with applicable law in all jurisdictions where the business operates;
• Privacy and data — Increasingly important: review of data handling practices, privacy policies, and compliance with PIPEDA and provincial privacy statutes.

Financial and Tax Due Diligence

Financial and tax due diligence examines the target's historical financial performance and the accuracy and integrity of its financial statements. In a share deal, the buyer is particularly concerned with:

• Historical income tax returns and CRA assessments — including any reassessment risk, loss carryforwards, and eligible capital property pools;
• HST/GST, payroll tax, and employer health tax compliance;
• Transfer pricing arrangements and related-party transactions that may be challenged on reassessment;
• Working capital levels relative to the normal course of business — underpinning any normalized working capital adjustment at closing; and
• Quality of earnings analysis — identifying whether reported EBITDA reflects sustainable operational performance or includes one-time items or accounting treatments that inflate earnings.

Tax due diligence in a share deal requires particular attention because all pre-closing tax liabilities, including those that have not yet crystallized as assessed, remain with the target and flow through to the buyer. Buyers commonly require a specific indemnity from the seller for pre-closing tax liabilities and the right to control any tax audits relating to periods prior to closing.

Employment and Benefits

Employment due diligence examines the structure of the target's workforce, its compensation and benefits obligations, and any outstanding employment disputes. Key areas include:

• Employment agreements — Change-of-control provisions in key employee agreements that may trigger severance obligations or resignation rights on closing;
• Common law notice obligations — The target's obligation to provide reasonable notice of termination (or pay in lieu) to employees not terminated for cause, which accrues over time and can represent a significant undisclosed liability;
• Pension and benefit plans — The funded status of any defined benefit pension plans, and any pension solvency deficiencies that travel with the target in a share deal;
• Human rights and ESA complaints — Any outstanding complaints to the Human Rights Tribunal or the Ministry of Labour; and
• Non-competition and non-solicitation agreements — Validity and enforceability of post-employment restrictions applicable to key personnel.

The Purchase Agreement

Letter of Intent and Term Sheets

Before the parties commit to a definitive purchase agreement, they typically record the key commercial terms in a letter of intent ("LOI") or term sheet. The LOI serves several functions: it confirms that the parties have reached agreement on the essential commercial terms (price, structure, exclusivity, and timeline), it creates a framework for due diligence and negotiation, and it establishes which provisions are binding from the outset.

Most LOIs are non-binding as to the principal transaction — meaning neither party is obligated to close — but contain a handful of binding provisions that take immediate effect:

• Confidentiality — Obligations to protect non-public information shared in the due diligence process, typically surviving termination of the LOI;
• Exclusivity — A "no-shop" or "standstill" period during which the seller agrees not to solicit or entertain competing offers, giving the buyer time to complete due diligence without competitive interference;
• Break fees — In public company transactions, a termination fee payable by the target board if it accepts a superior proposal or withdraws its recommendation; and
• Governing law and dispute resolution — Jurisdiction and applicable law for any disputes arising from the LOI itself.

Representations and Warranties

Representations and warranties are statements of fact made by each party as of the signing date (and typically again as of closing). They are the primary mechanism by which the buyer allocates the risk of undisclosed liabilities to the seller. If a representation proves to be untrue, the buyer may have a claim for breach of the purchase agreement, triggering the indemnification provisions.

In a typical share purchase agreement, the seller makes representations covering:

• Organization and authority — The target is duly incorporated and in good standing; the seller has the authority to enter into the agreement and no consents are required that have not been obtained;
• Capitalization — The shares are validly issued and outstanding, free and clear of encumbrances; there are no outstanding options, warrants, or convertible securities;
• Financial statements — The target's financial statements fairly present its financial position in accordance with applicable accounting principles; there has been no material adverse change since the most recent balance sheet;
• Absence of undisclosed liabilities — No material liabilities exist other than those disclosed;
• Compliance with law — The target has complied with all applicable laws and holds all required licences and permits;
• Material contracts — All material contracts are valid, binding, and in full force and effect; there are no defaults or termination rights triggered by the transaction;
• Litigation — There are no pending or threatened claims that could materially affect the target or the transaction;
• Intellectual property — The target owns or has the right to use all IP material to its business; there are no infringement claims;
• Environmental — The target is in material compliance with environmental laws and there are no known environmental liabilities;
• Employees and labour — There are no labour disputes, and the target is in compliance with employment standards legislation; and
• Taxes — All tax returns have been filed and all taxes paid; there are no outstanding assessments, reassessments, or tax audits.

Representations are typically qualified by materiality — a representation that the target has complied with all laws is impractical without a materiality qualifier, as some degree of technical non-compliance is nearly universal. Sellers negotiate hard for broad materiality qualifiers (e.g., "in all material respects") and "knowledge qualifiers" (limiting the representation to matters within the seller's knowledge). Buyers resist these limitations, because a narrowly qualified representation provides less protection.

The disclosure schedules attached to the purchase agreement are as important as the representations themselves. Any matter disclosed in the schedules is treated as qualifying the corresponding representation — if the seller discloses a known lawsuit, the buyer is deemed to have accepted the risk of that lawsuit. Counsel on both sides must review the disclosure schedules meticulously, as the schedules define the actual scope of the seller's representations at closing.

Indemnification and Risk Allocation

The indemnification provisions of a purchase agreement determine who bears the financial cost of a misrepresentation or breach of covenant discovered after closing. Sellers indemnify buyers for losses arising from breaches of the seller's representations and warranties; buyers typically indemnify sellers for post-closing liabilities assumed by the buyer.

The key negotiated parameters of an indemnification regime are:

• Survival period — The period during which a claim for breach of representations can be made. General commercial representations typically survive 18 to 24 months after closing; fundamental representations (organization, capitalization, title to shares) and tax representations survive for the applicable limitation period. Fraud claims typically survive indefinitely;
• Deductible / basket — A minimum threshold of aggregate losses that must be exceeded before the indemnification obligation is triggered. This may be a "tipping basket" (once exceeded, the full amount from dollar one is recoverable) or a "deductible" (only losses above the threshold are recoverable);
• Cap — The maximum aggregate indemnification obligation of the seller, typically expressed as a percentage of the purchase price. General rep and warranty claims are often capped at 10–20% of the deal price; fundamental representations may be capped at 100%;
• Specific indemnities — Indemnities for identified known risks (such as a specific tax exposure or pending litigation) that are carved out of the general basket and cap and are fully indemnified;
• Representations and warranties insurance — Increasingly common in mid-market transactions, RWI policies allow the buyer to claim against an insurer for breach of representations rather than the seller, effectively replacing the indemnification regime with insurance coverage. This is particularly useful where the seller wishes to achieve a clean exit.

Conditions to Closing

The purchase agreement typically does not require the parties to close immediately upon execution — instead, closing is conditional on the satisfaction (or waiver) of specified conditions. Conditions protect each party's ability to walk away if the deal fundamentals change materially before closing. Common conditions include:

The material adverse change ("MAC") or material adverse effect ("MAE") condition is among the most negotiated provisions in any purchase agreement. A MAC clause permits the buyer to refuse to close if a materially adverse change in the target's business, financial condition, or results of operations has occurred between signing and closing. The definition of what constitutes a MAC — and what is excluded from the definition (such as general market conditions, industry-wide changes, or the announcement of the transaction itself) — is heavily negotiated and has been the subject of significant litigation.

Earn-Outs and Purchase Price Adjustments

Where the buyer and seller cannot agree on a fixed price, or where the buyer requires that future performance underpin part of the consideration, the parties may structure part of the purchase price as an earn-out — a contingent payment tied to the target's post-closing performance against specified metrics. Common earn-out metrics include revenue, EBITDA, gross profit, or the achievement of specific milestones.

Earn-outs introduce complexity and post-closing conflict. Sellers must ensure that earn-out covenants prevent the buyer from operating the target in a way that artificially suppresses the earn-out metric. Buyers resist being constrained in how they operate a business they now control. Key issues include:

• The definition of the financial metric (particularly for EBITDA, where accounting choices can significantly affect the result);
• Whether the buyer is required to operate the target as a standalone entity or as an integrated part of the buyer's group;
• Dispute resolution mechanisms if the parties disagree on the earn-out calculation; and
• Acceleration provisions if the buyer sells the business during the earn-out period.

In addition to earn-outs, most purchase agreements provide for a purchase price adjustment based on the target's working capital at closing relative to a normalized working capital target. This adjustment ensures that the seller has not depleted the target's working capital between signing and closing. The adjustment is calculated by comparing actual working capital at closing to an agreed target level, with a dollar-for-dollar adjustment to the purchase price for any shortfall or excess.

Corporate Law and Director Duties

Director Duties and Business Judgment

Directors of a corporation considering a major transaction — including a sale of the corporation or its assets — owe fiduciary duties to act in the best interests of the corporation and a duty of care to act as a reasonably prudent director. These duties govern the entire M&A process from the initial assessment of whether to transact, through the negotiation of terms, to the recommendation to shareholders.

Courts are reluctant to interfere with the business judgment of directors in structuring or approving a transaction. The business judgment rule protects directors from personal liability for decisions made on an informed basis, in good faith, and in the honest belief that the decision is in the best interests of the corporation. As one court stated: "a Board of Directors is entitled to exercise its judgment as to what is in the best interests of the corporation in choosing an appropriate, lawful transactional structure to achieve business objectives."

However, the business judgment rule does not provide a shield against decisions made in conflict of interest, or where the board has failed to inform itself adequately before acting. In the M&A context, directors may face challenges where:

• A director has a personal financial interest in the outcome of the transaction (e.g., as a selling shareholder or a management-led buyout);
• The board has not conducted an adequate market process before recommending a sale;
• The board has adopted defensive measures that entrench management at the expense of shareholders;
• The board has approved a transaction that is not in the best interests of minority shareholders.

Some directors will go to extraordinary lengths to document their deliberations in arriving at the best disposition for the benefit of the corporation — engaging investment banks, commissioning fairness opinions, establishing special committees of independent directors, and retaining separate legal counsel. This documentation is critical if the decision is subsequently challenged in litigation.

Shareholder Approval Requirements

Not all M&A transactions require shareholder approval — the CBCA and OBCA reserve certain decisions for shareholders, while permitting the board to act without shareholder approval in other circumstances.

Shareholder approval by special resolution (at least two-thirds of the votes cast) is required under the CBCA and OBCA for:

• A long-form amalgamation;
• A sale, lease, or exchange of all or substantially all of the corporation's property other than in the ordinary course of business;
• An amendment to the articles of incorporation affecting share rights;
• A continuance into another jurisdiction;
• A voluntary dissolution or winding up.

By contrast, a board may generally approve a share purchase agreement (selling the corporation's shares from a third-party purchaser's perspective) without shareholder approval, since the target's shareholders are the selling parties and are themselves consenting to the transaction. Similarly, a short-form vertical amalgamation between a parent and its wholly owned subsidiary requires only board approval of each amalgamating corporation, not a shareholders' meeting.

Shareholders who oppose a transaction requiring their approval may exercise dissent and appraisal rights under the CBCA or OBCA, requiring the corporation to purchase their shares at fair value as determined by the court. Dissent rights are an important protection for minority shareholders and must be disclosed to shareholders in any materials sent in connection with a shareholder vote on a fundamental change.

Fairness Opinions

A fairness opinion is a written opinion provided by an independent financial adviser to the board of directors confirming that the consideration to be received in a transaction is fair, from a financial point of view, to the shareholders. Fairness opinions are not required by law — a board may approve a transaction without one — but they are standard practice in public company M&A and are increasingly common in significant private company transactions.

The purpose of a fairness opinion is twofold: it provides the board with an independent assessment of value to support its business judgment, and it documents the fact that the board undertook an informed process before recommending the transaction to shareholders. As courts have noted, a fairness opinion does not replace the board's own assessment — directors are not entitled to abdicate their judgment to the adviser. However, a fairness opinion is a significant indicator that the board acted in an informed and reasonable manner.

Fairness opinions must come from qualified, independent advisers — a financial institution or advisory firm with no material conflict of interest in the transaction. Where the adviser is also acting as placement agent, lender, or transaction broker, its independence may be compromised, and a second independent opinion may be required to satisfy the board's fiduciary obligations.

Competition Law

Competition Act Overview

Planning for any major business acquisition or reorganization in Canada must include consideration of the Competition Act, R.S.C. 1985, c. C-34. The Competition Act is the primary federal statute governing the competitive effects of mergers, and it grants the Commissioner of Competition broad powers to review and challenge transactions that may substantially lessen or prevent competition in any Canadian market.

The Competition Bureau — the administrative body that enforces the Act under the direction of the Commissioner — reviews mergers at two levels: a substantive review of the transaction's competitive effects, and a pre-notification review of transactions meeting specified size thresholds. Both levels of review can affect timing, deal structure, and the terms upon which a transaction proceeds.

Definition of Merger

A merger is specifically defined by section 91 of the Competition Act as the acquisition or establishment, direct or indirect, by one or more persons, whether by purchase or lease of shares or assets, by amalgamation or by combination or otherwise, of control over or significant interest in the whole or a part of a business of a competitor, supplier, customer, or other person.

This definition is deliberately broad. It captures not only formal share and asset purchases, but also the acquisition of a "significant interest" — which is largely understood to be control in fact. Acquisition of de jure control constitutes a merger — meaning acquisition of more than 50% of the voting shares, permitting the election of a majority of the board of directors. However, the Act also looks to de facto control: the test for de facto control is not based on "operational control" but rather asks whether a person or group of persons has the ability to exercise a decisive influence over the strategic or operational decisions of the corporation.

A merger can occur both at the time of the purchase of convertible debentures, non-voting shares, or options and at the time of their conversion or exercise, depending on whether the acquisition gives rise to a significant interest. Counsel must assess whether a proposed investment — even a minority investment — triggers merger review obligations.

Anti-Competitive Effects and Thresholds

The Bureau's substantive review of a merger focuses on whether the merger will substantially prevent or lessen competition in a relevant market. A substantial prevention or lessening of competition results only from mergers that are likely to create, maintain, or enhance the ability of the merged entity, unilaterally or in coordination with others, to exercise market power.

The Bureau's review proceeds through a structured framework:

1. Market definition — The Bureau defines the smallest group of products and geographic area in which a sole profit-maximizing seller could impose a small but significant and non-transitory price increase. This is the "SSNIP" (Small but Significant and Non-Transitory Increase in Price) test;
2. Market concentration — The Bureau identifies market shares and concentration levels (using the Herfindahl-Hirschman Index) to determine whether the merged entity would hold a dominant position;
3. Safe harbours — The Commissioner generally will not challenge a merger on the basis of unilateral exercise of market power where the merged entity's post-merger market share would be less than 35%; and generally will not challenge on the basis of coordinated effects where the four-firm concentration ratio (CR4) would be less than 65% or the merged entity's share would be less than 10%;
4. Entry analysis — The Bureau assesses whether timely, likely, and sufficient entry by potential competitors would prevent the merged entity from exercising market power after the transaction; and
5. Remedies — Where a merger raises competition concerns, the Bureau may seek consent agreements (requiring divestitures or behavioural commitments) or, in contested cases, apply to the Competition Tribunal for an order dissolving the merger or requiring divestiture.

Pre-Notification Requirements

Part IX of the Competition Act requires parties to notify the Commissioner before completing transactions that exceed prescribed size thresholds. Failure to notify is a criminal offence subject to a fine of up to $50,000 per day of non-compliance.

As of current thresholds, notification is generally required when:

• The parties and their affiliates together have assets in Canada or annual gross revenues from sales in or from Canada exceeding $400 million (the "size of parties" threshold); and
• The value of the assets in Canada or the annual gross revenues from Canadian sales of the target business (or, in the case of share acquisitions, the corporation whose shares are being acquired) exceeds $93 million (the "size of transaction" threshold), subject to adjustment from time to time.

For share acquisitions, notification is also required where the acquiror will hold more than 20% of the voting shares of a public corporation or more than 35% of a private corporation, and those thresholds have not already been exceeded. The notification filing triggers a mandatory waiting period — typically 30 days — during which the parties may not complete the transaction. The Bureau may request additional information within this period, which restarts the waiting period clock.

Where a transaction does not raise competition concerns, the parties may apply for an Advance Ruling Certificate ("ARC") or a no-action letter, providing comfort that the Commissioner will not challenge the merger. Parties are encouraged to engage with the Bureau's Prenotification Unit prior to filing to discuss whether short-form or long-form notification is required and whether an ARC is appropriate.

Efficiency Defence

Section 96 of the Competition Act provides a defence to an otherwise anti-competitive merger if the efficiency gains brought about by the merger are greater than and offset the anti-competitive effects. This is known as the "efficiency defence" — and it was, for many years, one of the most distinctive and controversial features of Canadian competition law.

The Bureau considers three types of efficiency gains relevant to the trade-off analysis:

• Allocative efficiency — the degree to which resources are allocated to their most valuable use;
• Productive (technical) efficiency — the creation of a given volume of output at the lowest possible resource cost; and
• Dynamic efficiency — the optimal introduction of new products and production processes over time.

The Federal Court of Appeal has confirmed that the offset requires the Tribunal to balance both quantitative and qualitative factors. Efficiency gains must be greater than and offset the anti-competitive effects — not merely equal to them. The merging parties bear the burden of proving all efficiency gains that would not be attained but for the merger; the Commissioner bears the burden of proving the anti-competitive effects. Recent legislative amendments have modified the efficiency defence — counsel should verify the current statutory language in connection with any merger review.

Investment Canada Act

Review Thresholds and Applicability

The Investment Canada Act ("ICA") establishes a mandatory review mechanism for acquisitions of Canadian businesses by non-Canadians. Where the ICA applies, the foreign investor must either notify the government or obtain ministerial approval before (or in some cases after) completing the investment. A failure to comply with the ICA can result in orders to divest the investment and substantial penalties.

The ICA applies to "investments" — which includes direct acquisitions of control of a Canadian business and indirect acquisitions where a foreign parent acquires control of an entity that itself controls a Canadian business. Acquisitions of control are assessed by reference to whether the foreign acquiror has acquired de jure control (more than 50% of voting shares) or, in some cases, de facto control.

Whether a transaction requires notification or full review depends on the value of the Canadian business being acquired and the nationality and sector of the acquiror:

Net Benefit to Canada Test

Where a transaction is subject to full ICA review, the Minister of Innovation, Science and Economic Development must be satisfied that the investment is likely to be of net benefit to Canada before it can proceed. The Minister assesses six factors:

1. Effect on the level and nature of economic activity in Canada, including employment;
2. Degree and significance of participation by Canadians in the Canadian business and any industry sector;
3. Effect on productivity, industrial efficiency, technological development, product innovation, and product variety;
4. Effect on competition within any industry or industries in Canada;
5. Compatibility of the investment with national industrial, economic, and cultural policies; and
6. Contribution of the investment to Canada's ability to compete in world markets.

Investment Canada reviews certain acquisitions in terms of a net benefit to Canada test, and as a matter of practice, the Bureau receives all Investment Canada filings and attempts to complete its competition evaluation of Investment Canada cases that do not appear to raise serious competition concerns in advance of any ministerial decision, so that a single integrated review process can be completed efficiently.

In practice, most ICA reviews are resolved by undertakings — commitments made by the investor to the Minister to maintain specified employment levels, R&D expenditure, headquarters location, or to protect specified assets. Undertakings are binding and enforceable, and are a key tool for obtaining ICA approval in cases where the net benefit assessment would otherwise be uncertain.

National Security Review

In addition to the net benefit review, the ICA contains a separate national security review process that can apply to any foreign investment — regardless of size or sector — where the investment could be injurious to national security. The national security review process is distinct from the net benefit review and can be triggered at any stage of the investment, including after closing.

National security reviews are initiated by the Minister of Public Safety and can result in conditions being imposed on an investment, or, in extreme cases, an order to divest. The government has taken an expansive approach to the definition of national security, and counsel advising on cross-border transactions must assess national security exposure in light of the target's activities, its customer base, and any involvement in sensitive technologies, critical infrastructure, or data.

Post-Closing Matters

Non-Competition and Non-Solicitation

Post-closing non-competition and non-solicitation obligations are standard in most M&A transactions. The seller (and, in private company deals, key principals who were actively involved in the business) typically covenant not to compete with the acquired business, not to solicit its customers or employees, and not to disparage the buyer or the business.

In the M&A context, courts are significantly more willing to enforce non-competition covenants than they would be in a purely employment context, because the vendor is receiving consideration for the goodwill of the business — and part of what the buyer is purchasing is the benefit of that goodwill. Courts recognize that a seller who sells a business and then immediately competes with it effectively keeps the value of the goodwill for itself while having been paid for it.

Courts have affirmed that the Employment Agreement containing confidentiality and non-competition provisions is a standard element of an M&A transaction, and that the parent's agreement to maintain the employees' employment with the company subject to their entering into employment agreements containing these provisions is a legitimate and enforceable part of the overall transaction structure.

Nevertheless, non-competition covenants must be reasonable in scope, duration, and geographic coverage. In Canadian courts, a covenant that is broader than reasonably necessary to protect the buyer's legitimate interest in the goodwill it has acquired will be struck down as unenforceable. Key parameters:

• Duration — Typically two to five years post-closing in an M&A context; courts have enforced covenants up to ten years in exceptional circumstances where the goodwill concern was particularly significant;
• Geographic scope — Must match the actual area in which the business operated; a worldwide restriction on a local business is unlikely to be enforced;
• Activity restriction — Must be limited to activities that actually compete with the acquired business; an overly broad restriction on all business activities will not be fully enforced.

Post-Closing Adjustments

Several post-closing financial adjustments are common in M&A transactions and require careful planning and documentation before closing to avoid disputes:

• Working capital adjustment — The final working capital is calculated as of the closing date and compared to the agreed working capital target; any shortfall or excess is paid by the seller or returned to the buyer as a purchase price adjustment. This process often involves a preparation period, a dispute resolution mechanism (typically an expert determination by an independent accountant), and defined accounting methodologies to prevent disputes over classification;
• Tax elections — In asset deals involving eligible capital property or depreciable assets, the parties may jointly elect under section 85 of the Income Tax Act to transfer assets on a tax-deferred basis, preserving the seller's cost base rather than triggering immediate recognition. The s. 85 rollover election allows the parties to allocate agreed amounts to each category of transferred asset and file a joint election with the CRA;
• Earn-out calculations — If the purchase price included an earn-out component, the buyer must prepare and deliver earn-out calculations for each relevant period, subject to the seller's rights of review and dispute resolution under the purchase agreement; and
• Indemnity claims — Buyers may make claims against the seller under the purchase agreement indemnification provisions during the survival period. The practical value of these claims depends on whether the seller is still funded and solvent, and on whether the buyer has the benefit of an escrow holdback or RWI policy as a direct source of recovery.

Integration and Transition

Successful execution of the purchase agreement is the beginning, not the end, of the M&A process. Post-closing integration — bringing the acquired business into the buyer's structure, culture, and operations — is one of the primary determinants of whether a deal creates value. Legal considerations in the integration phase include:

• Corporate housekeeping — Filing amendments to corporate records, registering new directors and officers, updating signing authorities, and completing any short-form amalgamation to merge the target into the buyer's group;
• Transitional services — In many transactions, the seller continues to provide certain services to the buyer (IT, payroll, accounting) for a transition period under a transitional services agreement ("TSA"). The TSA must be carefully drafted to define the services, service levels, pricing, and duration;
• Employee communications and cultural integration — Managing the human dimension of integration, including change of control communications to employees, harmonization of benefit plans, and assessment of redundancies;
• Regulatory notifications — Post-closing notifications to regulators and licensing authorities of the change in ownership or control of the business; and
• Retained records — The buyer must preserve records required for tax purposes, litigation, or regulatory compliance for the applicable retention periods, and the allocation of records between the buyer and seller must be addressed in the purchase agreement.
