How Long Do I Have to File a Civil Appeal in Ontario? Every Deadline Explained

The question we hear most often from clients considering an appeal is also the most urgent one: “How long do I have to file?” The answer matters more than most people realize. The deadline for filing a notice of appeal is short, the consequences of missing it can be severe, and the limited mechanisms available to extend the deadline are discretionary and far from guaranteed. A would-be appellant who waits too long can find themselves with no avenue to challenge a decision that they otherwise had strong grounds to appeal.

What makes this area particularly treacherous is that there is no single answer. The deadline depends on the court that issued the decision being appealed, the appellate court to which the appeal will go, whether the appeal is “as of right” or requires leave (permission) of the court, and the type of order being appealed. Some appeals must be commenced within seven days. Others have 15 days. Most civil appeals in Ontario have 30 days. The Supreme Court of Canada operates on a 60-day timeline. And each of these deadlines has its own starting point, its own rules about how time is computed, and its own consequences for missing it.

This article is a comprehensive guide to the time limits for filing civil appeals in Ontario. It covers the deadlines for appeals from interlocutory orders to a single Superior Court judge, appeals to the Divisional Court, appeals to the Court of Appeal for Ontario, motions for leave to appeal, and applications for leave to the Supreme Court of Canada. It explains how the deadline is calculated, what “service” and “filing” mean in this context, and what is available when the deadline has passed. It is written for parties who have just received a decision and are deciding whether to appeal, for parties who have already missed a deadline and need to understand their options, and for anyone advising on a potential appeal. Our civil appeals practice regularly handles all categories of civil appeals in Ontario.

Why the Deadline Matters: The Doctrine of Finality

Before turning to the specific deadlines, it is worth understanding why they are so strictly enforced. Civil appeals are time-limited for a reason. Once a court has rendered a final decision, the parties (and indeed the public) have an interest in knowing that the decision is final. The successful party needs to be able to enforce the judgment, the parties need to be able to plan their affairs around the outcome, and the integrity of the civil justice system depends on the principle that litigation has an end point.

The deadlines for filing appeals are the mechanism by which this finality is achieved. If an appeal is not commenced within the prescribed time, the decision becomes final and is no longer subject to challenge. Extensions of time are available, but they are discretionary, fact-specific, and subject to a framework that explicitly considers the prejudice to the successful party and the public interest in finality. Compliance with appellate procedure is treated as a matter of substantive importance, not mere formality.

This means that the moment a decision is rendered, the clock starts running. Anyone considering an appeal must move quickly to obtain legal advice, identify the applicable deadline, determine the correct appellate court, and prepare the necessary materials.

The Standard Civil Appeal Deadlines in Ontario

Most civil appeals in Ontario are governed by the Rules of Civil Procedure, with the time limits varying depending on the appellate court and the nature of the order being appealed.

Appeals to the Court of Appeal for Ontario: 30 Days

The most common deadline for civil appeals in Ontario is 30 days. Under rule 61.04 of the Rules of Civil Procedure, an appeal to the Court of Appeal for Ontario (and to the Divisional Court, where the appeal lies to that court as of right) must be commenced by serving a notice of appeal in Form 61A (or, for Divisional Court appeals, Form 61A.1) on every party whose interest may be affected by the appeal, within 30 days following the making of the order appealed from.

The notice of appeal must state the relief sought, the grounds of appeal, and the basis for the appellate court’s jurisdiction. It must also be accompanied by an appellant’s certificate respecting evidence in Form 61C. After service, the notice of appeal must be filed with the Registrar of the appellate court within 10 days following service.

The 30-day deadline runs from the date the order is “made,” which generally means the date the judge pronounced the decision in open court or by released reasons, regardless of when the formal order is signed, issued, or entered. There is an important and frequently misunderstood exception: where substantial issues concerning the settlement of the judgment or order remain after the initial date of pronouncement, courts have sometimes treated the 30-day clock as running from the date those issues are resolved. The Court of Appeal in Permanent Investment Corp. v. OPS (Township) held that a subsequent amendment to an order by the judge who pronounced the original order operated to extend the date of the order, for the purposes of the time within which to appeal, to the date of the amendment. The exception applies only to substantive issues that affect the determination of the case. Deferred costs decisions, as explained in their own section below, do not trigger this exception.

The general rule, however, is that the clock starts at pronouncement. Litigants should not wait for the formal order to be issued before commencing the appeal. Many a would-be appellant has been caught out by assuming that the deadline runs from the date the formal order is entered, only to discover that the clock began running when the judge first delivered reasons.

Appeals to the Divisional Court: 30 Days

Where the appeal lies to the Divisional Court as of right (rather than with leave), the same 30-day deadline applies. The Divisional Court has jurisdiction over a range of civil appeals, including appeals from final orders of the Superior Court of Justice for the payment of monetary amounts below a specified threshold, appeals from many administrative tribunals where the governing statute directs that the appeal lies to the Divisional Court, and appeals from Small Claims Court decisions involving claims above $2,500.

The procedure for commencement is governed by rule 61.04 and is essentially the same as for an appeal to the Court of Appeal, except that the notice of appeal is in Form 61A.1 (rather than 61A) and is filed in the Registrar’s office in the regional centre of the region in which the appeal is to be heard.

Appeals from Interlocutory Orders of an Associate Judge: 7 Days

For appeals from interlocutory orders of an associate judge of the Superior Court of Justice (formerly called “masters”), and from costs assessments, the time limit is much shorter. Under rule 62.01 of the Rules of Civil Procedure, the appeal must be commenced within seven days following the date of the order or certificate of assessment, by serving a notice of appeal in Form 62A on all parties whose interests may be affected.

The notice of appeal must name the first available hearing date that is not less than seven days after the date upon which the notice of appeal is served, and the notice of appeal is to be filed in the court office at least seven days prior to the hearing date.

These appeals proceed to a single judge of the Superior Court of Justice. The compressed seven-day timeline reflects the interlocutory nature of the orders being appealed: courts want these issues resolved quickly so that the underlying litigation can proceed. The Ontario High Court in Courtney v. Schneider held that a pending interlocutory appeal could not proceed once the trial of the action had begun, which underscores the urgency of moving quickly.

Motions for Leave to Appeal: 15 Days

Some categories of orders cannot be appealed as of right, but only with leave (permission) of the appellate court. For these appeals, the first step is not a notice of appeal but a motion for leave to appeal, and the time limit for that motion is 15 days.

Under rule 62.02 of the Rules of Civil Procedure, a motion for leave to appeal to the Divisional Court (from, for example, an interlocutory order of a Superior Court judge, certain final orders for costs only, or certain tribunal orders) must be served within 15 days after the date of the order from which leave to appeal is sought. The motion is heard in writing by a panel of the Divisional Court, without the attendance of parties or lawyers, and the substantive test for leave under subrule 62.02(4) requires either (a) a conflicting decision by another judge or court in Ontario or elsewhere on the matter involved and the panel’s view that leave should be granted, or (b) good reason to doubt the correctness of the order and the appeal involves matters of such importance that leave should be granted.

Statutory appeals to the Divisional Court that require leave are also governed by rule 61.03, with the same 15-day deadline. Where leave is granted, the appellant is required to deliver a notice of appeal and certificate respecting evidence within seven days of the granting of leave, and thereafter to comply with the regular provisions of rule 61 as in an appeal as of right.

For motions for leave to appeal to the Court of Appeal for Ontario, the motion materials are governed by rule 61.03.1, and the same 15-day initial deadline applies.

Appeals to the Supreme Court of Canada: 60 Days

Where a party wishes to appeal further from a decision of the Court of Appeal for Ontario to the Supreme Court of Canada, the procedure is governed by the Supreme Court Act and the Rules of the Supreme Court of Canada. Most appeals to the Supreme Court of Canada require leave of that court, and the application for leave must be served and filed within 60 days of the date of the judgment appealed from.

The 60-day deadline is a creature of statute (section 58 of the Supreme Court Act) rather than of rule, and accordingly the timeline cannot be extended by reference to the Rules of Civil Procedure or by reliance on the inherent jurisdiction of the Ontario courts. Extensions are sought from the Supreme Court of Canada itself, under rule 6 of the Rules of the Supreme Court of Canada.

For the very limited categories of appeals that lie to the Supreme Court of Canada as of right (such as certain criminal appeals not relevant here), the time limit is similarly set by statute and is similarly subject only to extensions granted by the Supreme Court itself.

How the Deadline Is Calculated

The calculation of the deadline is itself a source of confusion and occasional disaster. Several technical rules govern the computation of time in Ontario appellate procedure.

The Starting Point

As discussed above, the deadline for filing an appeal runs from the date the order appealed from is “made.” This is generally the date the judge pronounced the decision, not the date the formal order is signed and entered. The general rule was confirmed in the Supreme Court of Canada’s nineteenth-century decision in Walmsley v. Griffith and has been consistently applied ever since.

This rule has important practical consequences. A judge who delivers reasons on January 15 starts the clock on that date, even if the parties take weeks to settle the formal language of the order and the order is not entered until much later. If the appellant waits for the formal order to be entered before commencing the appeal, they may inadvertently miss the deadline.

There are limited exceptions to this rule. Where the judge has indicated that further consideration is required, where substantial issues remain about the form of the order, or where there are subsequent material amendments to the order, courts may treat the clock as running from the later date. But these are exceptions, and the cautious approach is to assume that the clock starts at pronouncement and to take steps within that timeline.

Counting the Days

The Rules of Civil Procedure set out specific provisions for the computation of time. Generally, where a period of time prescribed by the rules is “seven days or more,” the period is counted in calendar days, including weekends. Where the period is “less than seven days,” weekends and public holidays are excluded. Where the last day of the period falls on a day on which the court office is closed (typically weekends, statutory holidays, and other days when the office is closed), the period is extended to the next day on which the office is open.

For the 30-day appeal deadline, this means that weekends are included in the count. An appellant whose deadline falls on a Monday that is a statutory holiday gets the benefit of an extra day; an appellant whose deadline falls on a Friday gets no such benefit.

Service vs. Filing

It is essential to distinguish between service and filing, because the rules treat them differently. To “serve” a document means to deliver it to the other party in accordance with the rules of service. To “file” a document means to deposit it with the court office. The 30-day deadline under rule 61.04 is a deadline for service of the notice of appeal on the other party. The filing requirement is a separate, subsequent step (10 days after service).

A notice of appeal that is served on the other party within 30 days, but not filed with the court within 10 days of service, is procedurally defective. The appeal may be deemed abandoned under subrule 61.14(2) unless the court orders otherwise. Conversely, a notice of appeal that is filed with the court within 30 days but not served on the other party is not validly commenced. The appellant must serve the notice on every party whose interest may be affected.

What If Costs Are Decided Later? A Common Trap

One of the most common scenarios that causes confusion about appeal timing is the deferred costs decision. A judge often issues reasons on the merits and then either invites written submissions on costs or reserves the question of costs to be decided separately. Costs can be addressed days, weeks, or even months after the merits decision. The natural question is whether the appeal clock starts when the merits decision is released, or whether it is paused until the costs decision is rendered. The answer is the former, and it is one of the most consequential rules in Ontario appellate procedure.

The Clock Does Not Wait for Costs

The leading authority is the Ontario Court of Appeal’s decision in Byers (Litigation Guardian of) v. Pentex Print Master Industries Inc.. Confirming earlier case law, the court held that where a judge gives a judgment on the merits and defers the decision on costs, the time for appealing the merits runs from the date of the merits judgment. The fact that costs remain to be decided is not a “substantial matter” that defers the running of the appeal clock.

The practical consequence is significant. An appellant who waits until the costs decision is released before commencing an appeal from the merits has, in nearly every case, missed the 30-day deadline on the merits appeal. The merits decision becomes final at the end of the 30 days, regardless of whether costs have been addressed. A litigant who is dissatisfied with the merits decision must commence the appeal within 30 days of that decision, even though the costs question remains outstanding.

Coordinating the Merits Appeal and the Costs Appeal

This rule creates a procedural awkwardness where a party wishes to appeal both the merits and the costs decision. The merits appeal must be commenced within 30 days of the merits decision. The costs decision, when later rendered, can also be appealed, but with two important qualifications.

First, costs-only appeals require leave. Under section 133(b) of the Courts of Justice Act, an appeal lies only with leave of the appellate court where the appeal is only as to costs that are in the discretion of the court. This is a meaningful restriction. A party that is satisfied with the merits decision but wishes to appeal only a costs award faces a higher hurdle than an appellant on the merits, because they must first persuade the appellate court that leave should be granted.

Second, where the appellant has already commenced an appeal from the merits and the costs decision is subsequently released, the proper procedure (as set out in Byers) is to amend the notice of appeal to add a motion for leave to appeal the costs judgment. This allows the merits appeal and the costs appeal to be heard together, which is generally a more efficient use of judicial resources and avoids the risk of inconsistent results. The amendment must be made within the 15-day deadline for the leave motion on the costs portion, calculated from the date of the costs decision.

What About Waiting Strategically?

In our experience, the temptation to wait until the costs award is released before deciding whether to appeal is common and entirely understandable. A losing party often wants to see “the full damage” before committing to the cost and effort of an appeal. The thinking usually goes something like this: “If the costs award is modest, maybe I will not bother appealing. If it is brutal, I will appeal everything.” There are also litigants who want to hold the appeal option as settlement leverage and prefer to keep the cost exposure on the table when negotiating. These motivations are rational from a commercial perspective. They are nonetheless traps from a procedural perspective.

The Byers rule forecloses each of them. The merits clock runs from the merits decision, full stop. A litigant who waits for the costs decision to assess the economics of the appeal will, in almost every case, find the merits appeal is out of time when they finally decide to proceed. At that point, they are no longer pursuing an appeal as of right; they are seeking an extension of time, subject to the four-factor test and the appellate court’s discretion. Waiting to “see what costs look like” is not a recognized basis for an extension under any of the four Enbridge factors. It is, if anything, evidence that the appellant did not form a bona fide intention to appeal within the 30-day period.

There is one narrow exception worth flagging. Where the costs award is not merely deferred but is part of what makes the underlying order “final” in the first place, the analysis may be different. For example, where the substantive remedy itself includes a costs component (such as an order that the defendant pay solicitor-client costs as part of the substantive relief, with quantum to be assessed), the order may not be a final order until that quantum is determined. This is a narrow exception that depends on the structure of the particular order, not on the deferral of an ordinary costs award. Where there is any doubt about whether the underlying order is final without the costs decision, the cautious approach is to file the appeal within 30 days of the merits decision and amend later if needed, rather than to bank on the exception.

Two related options sometimes preserve flexibility without falling into the trap. First, where the other party has appealed first, a cross-appeal can be filed within 15 days after service of the notice of appeal under rule 61.07, and the cross-appeal can include grounds related to the costs award once it is released. Second, where the appellant has no real ground to challenge the merits but expects to challenge a forthcoming costs award, the appellant can simply wait for the costs decision and pursue a costs-only appeal with leave under section 133(b) of the Courts of Justice Act, calculated from the date of the costs decision. Neither of these is a workaround for missing the merits deadline. They are independent procedural pathways with their own timing rules.

The Practical Recommendation

Where there is any possibility of an appeal, the prudent course is to commence the merits appeal within 30 days of the merits decision, even if the costs question has not yet been resolved. The notice of appeal can be amended later to add the costs ground, if a costs appeal is warranted after the costs decision is released. Waiting for the costs decision is not a safe strategy. It will almost always result in the merits appeal being out of time, with extension of time being available only at the discretion of the appellate court and on the basis of the four-factor test discussed below.

Where the merits decision is favourable and only a costs award is contested, the would-be appellant should focus on the 15-day deadline for the leave motion under rule 62.02, calculated from the date the costs decision is released. This is a separate procedural pathway, and the timeline is even shorter than the 30-day merits deadline. Counsel should be retained immediately when costs are released to ensure that the leave motion is prepared and served on time.

Extension of Time: What Happens If You Miss the Deadline

If the deadline for filing an appeal has been missed, the would-be appellant is not necessarily out of options, but the path forward is significantly more difficult and is no longer a matter of right.

The Court’s Discretion to Extend

Rule 3.02 of the Rules of Civil Procedure provides that the court may, by order, extend or abridge any time prescribed by the rules, on such terms as are just. The motion for an extension can be made before or after the expiration of the time prescribed, which means that an applicant whose deadline has already passed can still bring a motion to extend it retroactively.

There is, however, an important limit. Rule 3.02(3) provides that an extension or abridgement of a time prescribed by the rules and relating to an appeal to an appellate court can be ordered only by a judge of that appellate court. An appellant who has missed the deadline to appeal to the Court of Appeal must bring the motion before a judge of the Court of Appeal, not before a judge of the court below. This is a frequent procedural trap for self-represented litigants.

A further limit, often overlooked, is that statutory time limits cannot be extended by reference to the rules of court unless the statute itself so provides. The Supreme Court of Canada in Murphy v. Welsh confirmed this principle. Where the deadline for filing the appeal is set by statute rather than by rule (as is the case for the 60-day deadline for applications for leave to the Supreme Court of Canada, and for some appeals from administrative tribunals), the rules of court may not provide a mechanism for extension. Extensions must instead be sought under the procedure provided in the governing statute, if any.

The Four-Factor Test

Where an extension is available, the Ontario Court of Appeal has developed a four-factor test that governs the discretion. The leading authority is Enbridge Gas Distribution Inc. v. Froese, where the Court of Appeal set out the factors that courts will consider in determining whether to grant an extension. The four factors are:

First, whether the moving party formed a bona fide intention to appeal within the relevant time period. This factor focuses on whether the appellant genuinely intended to appeal during the 30 days (or other applicable period), as evidenced by communications, retainers, or other contemporary indicators. An appellant who only formed the intention to appeal after the deadline had passed faces a significantly harder case.

Second, the length of the delay and the explanation for it. A short delay with a good explanation (inadvertence by counsel, illness, a need to obtain transcripts before formulating grounds of appeal) will be viewed more favourably than a long delay with no real explanation. The Court of Appeal has been clear that the absence of any explanation for delay is fatal to the motion.

Third, any prejudice to the responding parties caused by the delay. This factor considers whether the successful party has acted on the assumption of finality (for example, by spending the judgment proceeds, by altering their commercial position, by losing key witnesses, or by destroying records). Prejudice can also include the broader prejudice to the integrity of the civil justice process, as the Court of Appeal recognized in 828343 Ontario Inc. v. Demshe Forge Inc..

Fourth, the merits of the proposed appeal. Where the proposed appeal lacks merit, the court will be reluctant to grant an extension. Where the appeal has some arguable merit, courts will generally lean toward granting the extension, particularly where the other factors are neutral or favourable. Lack of merit alone can be a sufficient basis to deny an extension, as the Court of Appeal confirmed in Enbridge Gas Distribution Inc. v. Froese.

Behind these four factors is an overarching test: the extension should be granted where “the justice of the case” requires it. A party is generally entitled to appeal and should not be deprived of that entitlement where there is no real prejudice to the other side. But the “justice of the case” is not a one-way street. It can also justify refusing an extension where the moving party has engaged in procedural misconduct or where the public interest in finality outweighs the appellant’s interest in proceeding.

When Extensions Are Refused

The Court of Appeal has refused extensions in a range of circumstances. In Dupuis v. Waterloo (City), the court refused an extension where the appellant twice failed to perfect its appeal due to technical errors and offered no explanation. In Hilltop Group Ltd. v. Katana, the Divisional Court characterized the appellants’ “stalling actions” as outrageous and granted a motion to quash. In Schwilgin v. Szivy, the court refused an extension to a self-represented litigant where there was little merit to the appeal and the litigant had unpaid costs awards against them.

The lesson is that the extension of time is genuinely discretionary, and the discretion is exercised against parties who have failed to act with reasonable diligence and have no good explanation for their delay. The deadline is not a soft target. It is a hard one, with limited and conditional escape valves.

Common Mistakes That Cost People Their Right to Appeal

Several patterns of mistake recur in motions to extend the time for appeal. Anyone considering an appeal should be aware of them.

Waiting for the Formal Order

As discussed above, the clock starts when the order is pronounced, not when it is entered. An appellant who waits for the formal order to be settled and entered before commencing the appeal can find themselves out of time. The cautious approach is to commence the appeal based on the pronouncement and to amend the notice of appeal later if necessary.

Waiting for the Costs Decision

A related and equally common mistake is to wait for the costs decision before commencing an appeal from the merits. As Byers confirms, the merits clock runs from the merits decision, regardless of whether costs have been addressed. An appellant who waits to see the costs award before deciding whether to appeal the merits will almost certainly be out of time on the merits appeal. If costs are also to be challenged after they are decided, the proper procedure is to commence the merits appeal within the 30 days and then amend the notice of appeal to add a costs motion for leave once the costs decision is released.

Appealing to the Wrong Court

The Ontario appellate framework includes the Superior Court of Justice (for appeals from interlocutory orders of associate judges), the Divisional Court (for many statutory appeals and for appeals from final orders below specified monetary thresholds), and the Court of Appeal for Ontario (for most other final orders). Commencing the appeal in the wrong court does not stop the clock. If the appellant subsequently realizes the error and tries to commence the appeal in the correct court, they may be out of time and require an extension. In Schwilgin v. Szivy, the Court of Appeal refused an extension where the self-represented appellant had incorrectly commenced the appeal in the Divisional Court.

Confusing Leave Deadlines with Notice Deadlines

Where an appeal requires leave, the relevant deadline is the 15-day deadline for the motion for leave, not the 30-day deadline for a notice of appeal. An appellant who treats a leave-required appeal as an appeal as of right and proceeds within 30 days rather than 15 days will be out of time on the leave motion. Once leave is granted, a separate seven-day deadline applies for delivering the notice of appeal.

Failing to Move Promptly Once Aware of the Problem

If the deadline has passed, the appellant should move immediately. Delay in moving for an extension is itself a factor that weighs against granting the extension. An appellant who realizes on day 31 that the deadline has been missed and brings an extension motion on day 32 is in a much better position than one who waits until day 60 or day 90.

Failing to Document the Intention to Appeal

The first Enbridge factor (whether the moving party formed a bona fide intention to appeal within the relevant time period) is often the most important. Appellants who can document that they formed the intention to appeal within the 30-day period (through emails to counsel, instructions to obtain transcripts, communications with the other side) are in a much stronger position than those who can only assert the intention without documentary support. Where an appeal is being contemplated, the cautious approach is to document the consideration in real time.

What to Do Right After a Judgment Is Released

Given the strict and varied deadlines, the period immediately following an adverse judgment requires prompt and careful action. The following checklist captures the principal steps.

First, identify the date the order was “made.” If reasons were delivered in open court, this is the date of pronouncement. If reasons were released in writing, it is typically the date on the reasons. If the order is to be settled by the parties before signing, the date is generally still the pronouncement date, unless substantial settlement issues remain.

Second, identify the applicable appellate court and the time limit. Is the appeal from a final order or an interlocutory order? Does the appeal lie as of right or does it require leave? Is the appellate court the Divisional Court or the Court of Appeal for Ontario? Each of these questions affects the applicable deadline.

Third, calculate the deadline carefully. Count the days from the date of pronouncement. Apply the rules for computation of time. Be conservative: if there is any doubt about when the clock started, assume the earlier date and act accordingly.

Fourth, retain appellate counsel promptly. The 30-day window (or 15-day, or 7-day) is short, and counsel will need time to review the record, identify grounds of appeal, and prepare the notice. Waiting until day 25 to retain counsel for a 30-day appeal is a recipe for stress, errors, and missed deadlines.

Fifth, order any transcripts that may be required. For appeals as of right under rule 61.04, an appellant’s certificate respecting evidence is required, and the ordering of transcripts can take significant time. The transcript process must begin early.

Sixth, if the deadline has already passed, move immediately for an extension. Document the intention to appeal as it was at the relevant time. Prepare evidence on the four Enbridge factors. Address any prejudice arguments proactively.

Conclusion

The deadlines for filing civil appeals in Ontario are among the most consequential time limits in Canadian civil litigation. They are short. They vary by court and by type of order. They are calculated from the date of pronouncement rather than the date of entry. They distinguish between service and filing, with separate deadlines for each. And they are enforced through a discretionary extension mechanism that is far from a guaranteed safety net.

For anyone facing an adverse judgment, the most important advice is to act quickly. Identify the date the order was made, identify the appellate court and the applicable deadline, retain experienced appellate counsel, and begin the work of preparing the appeal as soon as possible. The right to appeal is a fundamental feature of the civil justice system, but it is a right that must be exercised within strict and unforgiving time limits.
