Insights & Analysis
Commercial litigation refers to the process of resolving disputes that arise in the course of business and corporate dealings. These disputes can range from contract breaches and shareholder disagreements to issues involving suppliers, customers, or regulatory bodies. While litigation may be necessary in certain cases, it is often complex, time-consuming, and costly. For this reason, businesses must approach litigation strategically, with an understanding of both the potential benefits and the risks involved.
It is almost inevitable that at some point in a corporation's life cycle, the involvement of legal counsel will be required to resolve disputes with third parties. Litigation may become necessary when negotiations fail, but in many instances, the mere prospect of litigation can encourage parties to reach a fair and equitable settlement.
In fact, the vast majority of disputes never reach trial. Statistics in Ontario show that more than 95 percent of all cases settle before trial, underscoring the importance of negotiation and alternative dispute resolution as part of the litigation landscape. Litigation — or the credible threat of it — is often what brings parties to the table. Effective strategy means knowing when to litigate and when to leverage the process toward resolution.
Because litigation can be both expensive and unpredictable, alternatives such as mediation or arbitration are frequently considered. Mediation involves the assistance of a neutral third party to help the disputing parties reach a mutually acceptable solution, while arbitration involves a binding decision made by an independent arbitrator. In many business contracts, these forms of dispute resolution may be mandated. Courts also increasingly require parties to attempt mediation before proceeding with litigation. These alternatives can save time, preserve business relationships, and reduce costs compared to a full trial.
Despite the availability of alternatives, some disputes cannot be resolved without resorting to the courts. Litigation, or even the threat of it, may be the only effective tool to compel a resolution when the opposing party refuses to engage in good faith. It provides a structured process where evidence is presented, legal rights are clarified, and enforceable remedies are granted. For some corporations, pursuing litigation is necessary not only to resolve a particular dispute but also to set an important precedent, protect business interests, or preserve the integrity of contractual obligations.
Commercial litigation encompasses a wide variety of disputes that arise in the business context. These matters often involve high financial stakes, regulatory issues, and complex contractual or corporate relationships. Common types of proceedings include:
Claims arising from the breach, interpretation, or enforcement of business contracts — the most frequent source of commercial litigation.
Claims against directors and officers for breach of statutory or common law duties of care, loyalty, or honesty owed to the corporation.
Emergency court orders — Mareva freezing orders, Anton Piller search orders, Norwich disclosure orders — to preserve rights and evidence before trial.
Disputes involving securities regulation, misrepresentation in disclosure documents, insider trading, shareholder rights, or market conduct.
Conflicts between shareholders and corporations, including oppression claims, derivative actions, and disputes over corporate governance in closely held companies.
Claims against corporate decision-makers for alleged breaches of duty, negligence, oppressive conduct, or misuse of authority in managing the corporation.
Litigation stemming from contract disputes lies at the heart of commercial litigation. Virtually every business transaction is built on agreements, whether formal contracts or informal arrangements that create legally enforceable obligations. When one party fails to perform its obligations, the aggrieved party may pursue remedies through the courts.
The central question in any contract case is: what remedy will place the innocent party in the position it would have been in had the contract been performed? The law generally seeks to protect the "expectation interest" — ensuring the injured party receives the value of what was promised, not merely compensation for out-of-pocket expenses. This framework gives commercial agreements their enforceability and certainty.
The most common remedy for breach of contract is damages, calculated as the difference between the contract price and the market price of goods or services, plus additional costs flowing directly from the breach. In exceptional cases, courts may grant equitable remedies such as specific performance — compelling the breaching party to perform — or injunctions restraining certain actions. These are particularly significant where monetary damages are inadequate, such as in contracts involving unique assets like land or intellectual property.
There are also instances where courts award nominal damages, recognizing the breach even where no substantial loss has been proven. Recent developments have also introduced the possibility of gains-based recovery, where damages are measured by the profit the breaching party wrongfully obtained rather than the innocent party's loss.
A key distinction in contract litigation is made between direct damages and consequential damages. Direct damages refer to the immediate financial loss caused by the breach, such as the cost of replacing undelivered goods. Consequential damages capture broader losses arising from the breach, such as lost profits from delayed production or disruption of business operations.
Courts apply the principle of remoteness of damages to limit recovery. Only losses that were reasonably foreseeable at the time the contract was made are recoverable. This ensures fairness and predictability while preventing limitless liability for downstream consequences. Defendants may also reduce their exposure by showing that the plaintiff failed to take reasonable steps to mitigate its losses following the breach — a duty that applies to all innocent parties.
The plaintiff in a contract dispute must prove the existence of a valid contract, the breach, and the damages suffered. The defendant may attempt to reduce liability by showing that the plaintiff failed to mitigate its losses or that certain damages fall outside the scope of what was foreseeable at the time of contracting. This allocation of proof underscores the importance of clear contractual drafting and diligent recordkeeping in commercial relationships.
Contract litigation extends beyond compensation. It enforces the principle that promises made in the marketplace carry legal weight and must be honoured. In doing so, it provides certainty and predictability for businesses that rely on contractual arrangements to allocate risks and responsibilities. For some litigants, pursuing contract claims is about more than recovering money — it is about upholding trust in commercial relationships and ensuring accountability.
Directors and officers occupy positions of trust and responsibility within corporations, subject to statutory duties and common law fiduciary obligations. These duties require directors to act honestly, in good faith, and in the best interests of the corporation. They are central to corporate governance and form the foundation for accountability in business relationships.
Directors must exercise the care, diligence, and skill of a reasonably prudent person in comparable circumstances — informed by adequate review, expert advice where appropriate, and the business judgment rule.
Directors must act in the corporation's interests rather than their own. Prohibits self-dealing, conflicts of interest, and misappropriation of corporate opportunities. Requires disclosure and often abstention from voting on conflicted matters.
Arising most often in closely held corporations — disagreements over strategy, dividends, executive compensation, succession, or in public companies: shareholder activism, proxy contests, hostile takeover defences.
Damages, disgorgement of profits, removal from office, or injunctive relief. In some cases, personal liability for authorizing unlawful distributions or failing to prevent corporate wrongdoing.
The duty of care requires directors and officers to exercise the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances. This does not mean directors must always make the correct decision — rather, they must inform themselves adequately before making decisions, seek expert advice where appropriate, and act on a reasonably informed basis.
Courts apply the business judgment rule, which provides that directors will not be held liable for decisions made in good faith, on an informed basis, and with a rational belief that the decision serves the corporation's best interests. This deference recognizes that business involves risk and that directors should not face personal liability for every unfavourable outcome. However, the business judgment rule does not protect grossly negligent conduct or decisions made without proper consideration of the facts.
The duty of loyalty requires directors to act in the corporation's interests rather than their own personal interests. This duty prohibits self-dealing, conflicts of interest, and the misappropriation of corporate opportunities. Directors must disclose any material interest in transactions with the corporation and, in many cases, abstain from voting on matters where they have a conflict.
Where a director diverts a corporate opportunity for personal gain, or enters into transactions that benefit themselves at the corporation's expense, they may be required to account for profits, compensate the corporation for losses, or face removal. Courts scrutinize transactions between directors and their corporations to ensure fairness and full disclosure.
Governance disputes often arise in closely held corporations where management and ownership overlap. Disagreements over strategic direction, dividend policies, executive compensation, or succession planning can escalate into litigation when directors or shareholders believe their interests are being unfairly disregarded. In publicly traded companies, governance disputes may involve shareholder activism, proxy contests, or challenges to board decisions regarding mergers, acquisitions, or defensive tactics against hostile takeovers. Courts balance the authority of directors to manage the corporation with the legitimate expectations and rights of shareholders.
When directors breach their fiduciary duties, remedies may include damages, disgorgement of profits, removal from office, or injunctive relief to prevent further breaches. In some cases, directors may also face personal liability for authorizing unlawful distributions or failing to prevent corporate wrongdoing. The goal of these remedies is to restore the corporation and its stakeholders to the position they would have occupied had the breach not occurred.
In commercial litigation, time is often critical. Injunctions and other forms of urgent relief allow parties to preserve their rights, prevent irreparable harm, and maintain the status quo while disputes proceed through the courts.
| Order Type | What It Does | Key Requirements |
|---|---|---|
| Interlocutory Injunction | Restrains a party from specific conduct (or compels it) before trial | Serious issue to be tried; irreparable harm; balance of convenience; undertaking as to damages |
| Mareva Order | Freezes defendant's assets within (or outside) the jurisdiction pending judgment | Strong prima facie case; real risk of dissipation; assets within jurisdiction or extraterritorial conduct justifying reach |
| Anton Piller Order | Authorizes entry to defendant's premises without notice to search for and seize evidence | Strong case; defendant possesses crucial materials; real possibility evidence will be destroyed; legal supervision required |
| Norwich Order | Compels a third party to disclose information identifying an unknown wrongdoer | Wrong committed; third party likely has relevant information and is the only practical source; just and convenient to order |
| Preservation Order | Requires maintenance of documents, electronic records, or physical evidence | Relevance to anticipated or existing litigation; risk of spoliation without an order |
An interlocutory injunction is a temporary court order granted before trial to prevent a party from taking certain actions or to compel specific conduct. Irreparable harm refers to injury that cannot be adequately compensated by damages — such as the loss of a unique business opportunity, damage to reputation, or disclosure of confidential information. The balance of convenience test requires the court to weigh the harm the applicant would suffer if the injunction is denied against the harm the respondent would suffer if it is granted.
Interlocutory injunctions are commonly sought in disputes involving breaches of non-compete agreements, misuse of trade secrets, intellectual property infringement, and wrongful interference with contractual relationships. Because these orders are made before a full trial, courts require the applicant to provide an undertaking to compensate the respondent for damages if it is later determined that the injunction should not have been granted.
A Mareva order (also known as a freezing order) restrains a party from dissipating or removing assets from the jurisdiction pending the outcome of litigation. These orders are typically sought where there is a real risk that a defendant will move assets beyond the reach of the court, making it impossible for the plaintiff to enforce any judgment obtained. Mareva orders are powerful remedies and are granted only where there is clear evidence of wrongdoing or a credible threat to the enforcement of the plaintiff's claim.
An Anton Piller order allows a plaintiff to enter the defendant's premises without prior notice to search for and seize evidence that might otherwise be destroyed or concealed. These orders are extraordinary remedies reserved for cases involving serious misconduct, such as intellectual property theft, fraud, or breaches involving highly sensitive information. The order must be executed in a manner that minimizes intrusion and respects the defendant's rights — legal supervision is typically required, and the defendant has the right to apply to set aside or vary the order after execution.
A Norwich order compels a third party to disclose information or documents that will help identify or locate a wrongdoer. These orders are frequently used in cases involving anonymous defendants, such as individuals operating under pseudonyms online or entities hiding behind corporate structures. Courts balance the need for disclosure against the rights of both the third party and the alleged wrongdoer, with privacy and confidentiality considerations carefully weighed.
Preservation orders require parties to maintain documents, electronic records, or physical evidence that may be relevant to litigation. These orders prevent spoliation — the destruction or alteration of evidence — and ensure that critical information remains available for discovery and trial. Preservation orders are particularly important in cases involving electronic data, where information can be easily deleted or overwritten, and should be sought early once litigation is anticipated.
Arbitration and alternative dispute resolution (ADR) offer parties a means of resolving commercial disputes outside the traditional court system. These processes are often faster, more flexible, and more cost-effective than litigation, while still providing binding and enforceable outcomes.
| Feature | Arbitration | Mediation | Court Litigation |
|---|---|---|---|
| Outcome | Binding award | Voluntary settlement (non-binding if no agreement) | Binding judgment |
| Privacy | Private and confidential | Confidential | Public record |
| Control | High — parties choose arbitrator, rules, seat, timeline | High — parties control outcome and can walk away | Low — court controls procedure and schedule |
| Speed | Often faster than litigation for complex matters | Can be very quick if parties are motivated | Slowest — court scheduling and backlog |
| Appeals | Very limited — narrow statutory grounds only | N/A — no award to appeal | Broad rights of appeal available |
| Enforcement | Enforceable like a court judgment; New York Convention applies internationally | Enforceable as a contract if settlement is documented | Directly enforceable; recognition abroad varies |
Commercial arbitration is a private dispute resolution process in which parties agree to submit their dispute to one or more arbitrators who render a binding decision. Unlike court proceedings, arbitration is confidential, and parties have significant control over the process, including the selection of arbitrators, the procedural rules, and the location of the hearing.
Arbitration is particularly well-suited to complex commercial disputes involving technical issues, international parties, or industry-specific matters where specialized expertise is valuable. In Ontario, arbitration is governed by the Arbitration Act, 1991, which provides a framework for the conduct of arbitrations, the enforcement of arbitration agreements, and the limited grounds on which arbitral awards can be challenged. Generally, arbitral awards are final and binding, with very narrow grounds for appeal or judicial review.
Mediation is a voluntary, non-binding process in which a neutral third party facilitates negotiations between disputing parties to help them reach a mutually acceptable settlement. Unlike arbitration or litigation, mediation does not result in a binding decision imposed by a third party — the parties retain control over the outcome and can walk away if they are unable to reach an agreement.
Courts in Ontario frequently require parties to attend mediation before proceeding to trial. The mediator's role is to assist the parties in identifying issues, exploring interests, and evaluating options without imposing decisions or providing legal advice. Anything said in mediation is typically confidential and cannot be used in subsequent litigation or arbitration.
Well-drafted dispute resolution clauses are essential to ensuring that arbitration and ADR mechanisms function as intended. These clauses should clearly specify whether disputes will be resolved through arbitration, mediation, or litigation, and should address the selection of arbitrators, the governing rules (such as the rules of the ADR Institute of Canada or the International Chamber of Commerce), the seat of arbitration, and the applicable law. Ambiguities or gaps in dispute resolution clauses can lead to preliminary disputes over jurisdiction and enforceability — clear drafting avoids unnecessary preliminary litigation.
One of the key advantages of arbitration is the enforceability of arbitral awards. In Canada, arbitral awards are enforceable in the same manner as court judgments. International arbitral awards are enforceable under the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (the New York Convention), to which Canada is a signatory — a framework that covers over 170 countries and makes international arbitral awards more reliably enforceable than foreign court judgments in most cross-border contexts.
Challenges to arbitral awards are limited to narrow grounds: lack of jurisdiction, breach of natural justice, or awards that are contrary to public policy. Courts have consistently resisted attempts to re-open awards on the merits, preserving the finality and predictability that makes arbitration commercially valuable. Parties who wish to preserve their right to appeal should expressly contract for it in their arbitration agreement, as the default statutory position provides very limited review.
Competition law aims to maintain fairness, preserve consumer choice, and prevent practices that distort or undermine a level playing field. Success in the marketplace must be achieved through innovation, efficiency, and consumer value — not through conduct that restricts or distorts competition. Findings of unlawful conduct can lead to substantial financial penalties, loss of market credibility, and long-term damage to relationships with consumers, investors, and regulators.
Competition and trade practices litigation involves disputes arising from laws that govern the interactions between businesses in the marketplace. Allegations of anti-competitive behaviour can take many forms — price-fixing and collusion between competitors, abuse of dominant market position, agreements that substantially lessen or prevent competition, misleading advertising, deceptive marketing practices, or restrictive trade practices that affect consumers or other businesses.
The complexity of competition litigation is heightened by its overlap with regulatory enforcement. In Canada, the Competition Bureau investigates and prosecutes violations of the Competition Act, but private parties may also seek civil remedies for losses suffered as a result of anti-competitive conduct. This dual system means that businesses may face not only government investigations but also parallel civil proceedings, each with significant reputational and financial consequences.
Litigation in this area often requires economic analysis, expert testimony, and the interpretation of complex statutes and regulatory frameworks. The outcome of a case may determine whether a business practice is lawful, whether damages must be paid to affected competitors or consumers, and whether structural remedies such as divestiture or behavioural restrictions will be imposed.
Securities litigation occupies a central role in commercial law because it deals directly with the integrity of capital markets and the protection of investors. It arises in situations where misrepresentation, insider trading, or failures in disclosure obligations undermine confidence in securities transactions.
At common law, securities litigation is often grounded in misrepresentation. Courts recognize three principal bases for liability: deceit (fraudulent misrepresentation requiring proof of an intentional falsehood intended to induce reliance), negligent misrepresentation (carelessness in providing inaccurate or incomplete information where a duty of care exists), and breach of contract (where misstatements in offering documents are treated as terms of the contractual bargain).
Intentional false statement made to induce another to act on it. Requires proof of knowledge of falsity or reckless indifference to truth — the highest threshold but no cap on damages.
Careless provision of inaccurate or incomplete information where a duty of care exists. Plaintiff must prove reliance on the misrepresentation — common in prospectus and advisory contexts.
Misstatements in offering documents treated as contractual terms. Allows rescission or damages on a contractual basis, often without needing to prove fraud or negligence.
Statutory civil liability under the Ontario Securities Act and related statutes expands investor protections. Misrepresentations in a prospectus, offering memorandum, takeover bid circular, or continuous disclosure document can all ground liability. Statutory liability for secondary market disclosure — capturing misleading public statements and failures to make timely disclosure — is particularly powerful: unlike at common law, the statute presumes reliance, and defendants must prove defences such as due diligence.
Insider trading — the use of material non-public information in securities transactions — undermines market integrity by giving insiders an unfair advantage. Liability may extend not only to the insider but also to those who pass on confidential information (tipping). Civil remedies can include damages payable to those disadvantaged by the improper trades, in addition to regulatory sanctions and potential criminal liability.
Directors and officers carry significant responsibilities in ensuring compliance with securities laws. They may be held personally liable for authorizing or permitting contraventions, such as misrepresentations in disclosure documents or failures in timely reporting. Courts balance these obligations with recognition that directors are not liable for every business judgment error, but rather for failing to meet the standard of care expected of a reasonably prudent director in their position.
Securities litigation serves a dual function. For investors, it provides a means of redress for financial losses caused by misconduct. For the market as a whole, it reinforces transparency, accuracy, and trust. By holding companies and their officers accountable, securities litigation contributes to the stability and credibility of capital markets, ensuring they function as reliable mechanisms for investment and growth.
Technology and digital commerce disputes arise from the growing reliance on electronic platforms for business transactions. As more agreements are entered into online, the application of traditional contract law to electronic dealings has created new challenges for courts and businesses alike.
Canada adopted the Uniform Electronic Commerce Act (UECA), establishing that electronic information and agreements cannot be denied legal effect solely because of their medium. Each province has enacted its own form of electronic commerce legislation with some variations. Courts have consistently applied well-established contract law principles to online dealings — clicking "I agree," exchanging emails, or engaging with digital platforms can create binding obligations with the same force as paper contracts.
Disputes often arise because the online environment raises unique issues around contract formation, timing, and jurisdiction. Questions may surface over whether a website listing constitutes a binding offer or simply an invitation to negotiate. Similarly, determining when and where acceptance of an online contract occurs can influence not only the validity of the contract but also which jurisdiction's laws apply. These issues become more complex when automated systems or electronic agents participate in contract formation without direct human involvement.
Technology and digital commerce disputes also extend beyond contract formation. Businesses must navigate conflicts over the enforceability of online terms and conditions, particularly when important clauses such as forum selection or liability exclusions are buried in digital agreements. Courts have grappled with whether such terms provide sufficient notice to consumers, and whether they can be enforced in circumstances that may appear unconscionable or contrary to public policy.
For businesses, the stakes in technology and digital commerce disputes are high. These conflicts often involve not only financial exposure but also reputational risks in a marketplace that depends on consumer confidence in online transactions. Effective legal guidance is essential to ensure compliance with evolving digital frameworks and to resolve disputes that test the boundaries of traditional contract law in a modern context.
International commercial litigation refers to disputes that cross national borders and involve parties from different legal systems. These cases often arise from contracts, trade agreements, financing arrangements, or joint ventures where obligations extend beyond a single jurisdiction. Resolving such disputes requires navigating not only different substantive laws but also procedural rules, enforcement mechanisms, and cultural expectations.
One of the defining features of international litigation is the diversity of legal systems. Common law jurisdictions — such as Canada, the United States, and the United Kingdom — emphasize adversarial proceedings, judicial precedent, and expansive discovery. Civil law jurisdictions, including much of Europe and Latin America, use more inquisitorial procedures, where judges play a central role in investigating facts and are more inclined to grant remedies such as specific performance. Despite these differences, pleadings, pre-trial procedures, trial, judgment, and appeals form the backbone of litigation in most jurisdictions, though discovery is largely absent in civil law systems.
Perhaps the most significant hurdle in international litigation is determining jurisdiction and enforcing judgments abroad. A judgment that is enforceable in one jurisdiction may not be recognized in another, and businesses must often rely on bilateral treaties, multilateral conventions, or the domestic laws of the jurisdiction where enforcement is sought.
| Framework | Scope | Key Benefit |
|---|---|---|
| 2005 Hague Choice of Court Convention | Exclusive jurisdiction and judgment recognition where parties have chosen a court in a contracting state | Enforces party-chosen forum; prevents parallel proceedings in signatory states |
| 2019 Hague Judgments Convention | Recognition and enforcement of foreign judgments in civil and commercial matters between contracting states | Brings greater consistency to cross-border judgment enforcement |
| New York Convention (1958) | Recognition and enforcement of foreign arbitral awards — over 170 signatory states | Most reliably enforceable cross-border mechanism; preferred for international contracts |
Court proceedings are usually public, meaning that filings, judgments, and often hearings are accessible to the general public. This transparency can be valuable for establishing precedent and accountability but may expose sensitive commercial information. Arbitration, by contrast, is generally private — for this reason, many international contracts include arbitration clauses to avoid the publicity of litigation. Businesses that find themselves in litigation must be prepared for the scrutiny that comes with public proceedings.
Courts and arbitral tribunals increasingly permit electronic filings and remote hearings through video or teleconferencing. These developments have reduced logistical costs for international proceedings but raised new concerns over confidentiality, cybersecurity, and the handling of sensitive data. Effective legal strategy now includes planning for data protection and secure digital communication throughout the litigation process.
Directors and officers are entrusted with the responsibility of managing corporations in accordance with statutory duties, fiduciary obligations, and principles of good governance. When they fail to act in the best interests of the company or its stakeholders, they may face personal liability. Claims against directors and officers arise most frequently in the context of privately held corporations, where decision-making is concentrated and relationships are often intertwined with family or close business ties.
Shareholders or other complainants bring claims on behalf of the corporation when directors fail to do so — typically in cases of misconduct or breach of duty. Leave of the court is required; courts impose a high threshold to filter legitimate from opportunistic claims.
Directors can be held personally liable where they have used their position to gain personal benefit or engaged in conduct that directly harmed minority shareholders or creditors — focus is on the impact of the conduct, not just intent.
Claims where directors breach contractual obligations owed to shareholders or fail to meet fiduciary duties of loyalty, honesty, and care — courts scrutinize self-interested conduct and unequal treatment of similarly situated stakeholders.
Although corporations are separate legal entities, courts have not hesitated to hold directors personally accountable when their actions cross the line into oppressive conduct. Cases have involved directors prioritizing their own loans over those of other shareholders, denying stakeholders access to financial information, or engaging in reorganizations that stripped value from the company to the detriment of others.
Personal liability does not require proof that directors acted in bad faith. Instead, courts focus on the impact of the conduct. Even if a corporate decision is lawful on its face, it may still give rise to an oppression remedy if its effect is to unfairly prejudice or disregard the interests of a stakeholder whose reasonable expectations have been violated. Directors must act in a way that respects the reasonable expectations of all stakeholders, not merely their own interests.
In extreme cases, oppressive conduct by directors may justify winding up a corporation or triggering shotgun clauses in shareholder agreements. Courts exercise this power sparingly, recognizing that dissolving a solvent business is a drastic step. However, where internal deadlock or persistent misconduct prevents a corporation from functioning properly, winding up may be the only equitable solution.
Shareholder disputes are among the most challenging forms of commercial litigation because they often combine business disagreements with personal conflicts. These disputes typically occur in closely held corporations where shareholders may also be directors, officers, or family members. When conflicts arise, they can threaten not only the financial stability of the business but also the relationships among those who operate it.
The oppression remedy is the most flexible and frequently used tool in shareholder litigation. It protects shareholders and other stakeholders against conduct that is oppressive, unfairly prejudicial, or that unfairly disregards their interests. Courts applying this remedy focus on whether the reasonable expectations of stakeholders have been violated.
Examples of oppressive conduct include exclusion from management, denial of access to corporate information, or diversion of corporate opportunities. The remedy is exceptionally adaptable: courts can order financial compensation, corporate restructuring, the buyout of minority shareholders, the appointment of an inspector, or restrictions on corporate conduct going forward. This flexibility makes the oppression remedy the most powerful tool available to minority shareholders in closely held corporations.
While the oppression remedy focuses on harm suffered by individual stakeholders, derivative actions address harm done to the corporation itself. A derivative action allows a shareholder or another complainant to bring a lawsuit on behalf of the corporation when those in control — usually the directors — are unwilling or unable to act. These claims often involve breaches of fiduciary duty, misappropriation of corporate assets, or other forms of misconduct by those who manage the corporation.
Because derivative actions interfere with the directors' authority to manage the company, they are considered an extraordinary remedy. Leave of the court is required before the claim can proceed, and judges will carefully assess whether the proposed action is in the best interests of the corporation — balancing the need to hold insiders accountable against the risk of burdening the corporation with unnecessary litigation.
Shareholder disputes may also give rise to claims under contract law, particularly where a shareholders' agreement sets out rights relating to management, share transfers, or exit mechanisms. Courts can enforce these agreements and, where necessary, award damages for breach. In addition, statutes provide remedies such as compliance orders, which require directors or corporations to comply with their legal duties, and inspection rights, which ensure shareholders can review financial and corporate records.
In extreme cases, courts may order the winding up of a corporation. This remedy is rare and typically reserved for situations where deadlock or misconduct makes it impossible for the corporation to continue operating fairly and effectively.
The Commercial List is a specialized court within the Ontario Superior Court of Justice in Toronto, designed to handle complex commercial disputes efficiently and effectively. Established in 1991, it was created in response to the need for a forum where time-sensitive business disputes could be heard by judges with deep expertise in commercial matters. Over time, its scope has expanded to cover a broad range of commercial litigation, and it has developed an international reputation as a model for specialized commercial courts.
The Commercial List hears cases involving key statutes such as the Bankruptcy and Insolvency Act, the Companies' Creditors Arrangement Act, the Personal Property Security Act, the Winding-up and Restructuring Act, the Pension Benefits Act, the Business Corporations Acts (Ontario and federal), and the Limited Partnerships Act. This wide jurisdiction makes the Commercial List the venue of choice for disputes involving insolvency, corporate reorganizations, shareholder disputes, securities matters, and complex contractual claims. In many cases, parties may choose to transfer proceedings from the general civil list to the Commercial List, provided a judge is satisfied that the matter falls within its scope.
A distinguishing feature of the Commercial List is the case management system. Each case is assigned to a judge who oversees it from start to finish, ensuring consistency and efficiency. This hands-on approach allows judges to develop familiarity with the issues, streamline procedures, and encourage timely resolution. The Commercial List is also known for its focus on timeliness — recognizing the urgency of many business disputes, the court provides expedited hearings and greater flexibility in scheduling. This responsiveness makes it particularly suited to cases where delay could cause irreparable harm, such as insolvency proceedings or urgent injunctions.
For corporations, stakeholders, and investors, the Commercial List offers several advantages. Its judges bring expertise in corporate and commercial law, which enhances the predictability and quality of decisions. Its procedures promote faster outcomes, minimizing disruption to business operations. Its emphasis on fairness and efficiency builds confidence in Ontario as a jurisdiction for resolving high-stakes commercial disputes. Because of its specialization, the Commercial List has also developed a strong reputation internationally — it is viewed as a model for specialized commercial courts, providing Ontario with a competitive advantage as a hub for commerce and investment.
