How Appeals Work in Ontario
Deadlines, courts, standards of review, costs, and an honest look at why most appeals fail
Parties who have just lost at trial usually ask two questions: can we appeal, and should we. The first is a question of procedure. The second is a question of judgment, and it is the one that actually decides whether an appeal is worth the money.
This guide explains the mechanics—which court hears which appeal, the deadlines, the standards of review, stays of enforcement, fresh evidence, timelines, and cost structure—in plain language, with the Ontario statute and rule references that govern each step. It then addresses the part most articles skip: why the majority of appeals fail, and how a disciplined appellate lawyer decides whether yours should be brought at all.
One warning up front. Litigants are accustomed to the two-year basic limitation period under the Limitations Act, 2002 for starting a lawsuit. Appeals run on a different clock entirely: 30 days, sometimes 15. The appeal window closes while most people are still absorbing the judgment.
Which Court Hears Your Appeal
Ontario splits civil appellate work between two courts under the Courts of Justice Act. The dividing lines are whether the order is final or interlocutory, and how much money is at stake.
Court of Appeal for Ontario
- Final orders of the Superior Court where more than $50,000, exclusive of costs, is in issue
- Most civil appeals as of right—no leave required
- Heard by a panel of three judges
Divisional Court
- Final orders for $50,000 or less
- Interlocutory orders—but only with leave
- Appeals from Small Claims Court judgments
- Judicial review and statutory appeals from most tribunals
A final order ends the litigation or finally disposes of a substantive right—a trial judgment, a summary judgment dismissing the claim. An interlocutory order decides a step along the way—a refusal to strike a pleading, a discovery ruling, most injunctions. The distinction is notoriously technical, and getting it wrong sends the appeal to the wrong court.
Tribunal matters have their own routes. Decisions of the Landlord and Tenant Board, for example, are appealed to the Divisional Court on questions of law only, under s. 210 of the Residential Tenancies Act, 2006. And for context on where claims start: Small Claims Court handles disputes up to $35,000, the simplified procedure under Rule 76 covers claims up to $200,000, and larger cases proceed under the ordinary procedure of the Superior Court—the origin court shapes the appeal route. Our Toronto appeal practice covers both appellate courts.
The 30-Day Deadline
For most civil judgments of the Superior Court, the notice of appeal must be served within 30 days of the date of the order, under Rule 61.04 of the Rules of Civil Procedure. Where leave is required to appeal an interlocutory order to the Divisional Court, the window to serve the notice of motion for leave is shorter—15 days.
Two practical points follow. First, the clock runs from the date of the order, not from when reasons are digested or a new lawyer is retained. Second, a missed deadline is not automatically fatal, but it requires a motion to extend time, and the court weighs whether the appellant formed the intention to appeal within the 30 days, the length of and explanation for the delay, prejudice to the respondent, and the merits of the proposed appeal. Weak merits sink extension motions.
The first month after judgment is also when strategic decisions compound: ordering transcripts, moving for a stay, assessing grounds. Parties who spend that month deliberating often arrive at counsel's office with the window already closed. If a judgment has gone against you, treat the appeal assessment as urgent even if the decision to appeal is ultimately no.
Standards of Review, in Plain Language
The single most important concept in appellate law is the standard of review—how much deference the appellate court gives the judge below. The governing framework comes from the Supreme Court of Canada in Housen v. Nikolaisen, 2002 SCC 33:
Questions of law: correctness
Did the judge state and apply the right legal test? On pure questions of law, the appellate court owes no deference. If the trial judge got the law wrong, the appellate court simply substitutes the correct answer.
Findings of fact: palpable and overriding error
Palpable means obvious—an error you can point to on the record, not merely a finding you disagree with. Overriding means it goes to the core of the outcome. Both are required. The trial judge saw the witnesses; the appellate court reads a transcript. A factual finding will not be disturbed just because another view of the evidence was open.
Mixed fact and law: deference, unless a legal error can be extracted
Most trial conclusions—was the contract breached, was the conduct negligent—mix law and fact. These attract the deferential standard unless the appellant can isolate an extricable error of law, such as applying the wrong test or ignoring a required element.
The same deference extends to summary judgment: since Hryniak v. Mauldin, 2014 SCC 7, a motion judge's exercise of the expanded fact-finding powers is reviewed with considerable deference. Our own appellate matter, Wei v. Ye-Hang Canada, 2026 ONCA 180, shows how these standards operate in practice on an appeal from summary judgment.
When Leave to Appeal Is Required
Not every order can be appealed as of right. Interlocutory orders of a Superior Court judge can only reach the Divisional Court with leave—permission granted sparingly, broadly where there are conflicting decisions or good reason to doubt the correctness of the order on a matter of general importance. The policy is deliberate: litigation would never end if every procedural ruling could be appealed mid-stream.
Above the Court of Appeal sits the Supreme Court of Canada, which hears civil appeals only with leave, applied for within 60 days. Leave is reserved for issues of public importance; for the overwhelming majority of Ontario civil cases, the Court of Appeal is the last stop.
The practical takeaway: if you are mid-litigation and unhappy with an interlocutory ruling, the realistic options are usually to build the record and press on, not to appeal. An experienced civil litigation lawyer will tell you which rulings are worth a leave motion and which are noise.
Stay Pending Appeal: Does the Judgment Still Bite?
Filing an appeal does not put the whole judgment on hold. Under Rule 63.01 of the Rules of Civil Procedure, delivering a notice of appeal automatically stays any provision of the order requiring the payment of money (support obligations excepted) until the appeal is decided. That automatic stay is what stops a money judgment from being enforced while the appeal runs.
Everything else keeps operating. Injunctions, orders for possession of property, orders for specific performance, and declarations are not automatically stayed. To suspend them, the appellant must move under Rule 63.02 and satisfy the familiar three-part test from RJR-MacDonald v. Canada: a serious issue on appeal, irreparable harm if the stay is refused, and a balance of convenience favouring the stay.
Respondents have countermeasures too. Under Rule 61.06, the court can order an appellant to post security for costs of the appeal—for example, where the appeal appears frivolous and the appellant lacks assets in Ontario to pay a costs award. In one of our reported enforcement matters, the Court of Appeal ordered a $35,000 security-for-costs payment against the appellant before the appeal could proceed. These motions are part of appellate strategy on both sides of the file.
Fresh Evidence: Rarely, and for Good Reason
An appeal is argued on the trial record. New evidence is admitted only exceptionally, on the test derived from Palmer v. The Queen: the evidence could not have been obtained for trial with due diligence, it is relevant and credible, and it could reasonably have affected the result.
Clients often arrive after trial with a document or witness they believe changes everything. The honest response is usually that the evidence either could have been found earlier—which defeats the motion—or would not have changed the outcome—which also defeats it. The time to build the evidentiary record is before and at trial, not after. This is one reason appellate counsel who also try cases tend to assess appeal prospects more accurately: they know what a complete record looks like.
Realistic Timelines and What an Appeal Costs
A civil appeal moves through defined stages: serving the notice of appeal (30 days), ordering trial transcripts, then perfecting the appeal under Rule 61.09— filing the appeal book, transcripts, and the appellant's factum—after which the court assigns a hearing date. The respondent files a responding factum, the panel hears oral argument, and judgment is frequently reserved. From notice of appeal to decision, roughly a year is a realistic planning figure at the Court of Appeal; heavy transcripts stretch it. Perfection deadlines are enforced: in one of our Divisional Court matters, the opposing appellant's failure to perfect for five months ended the appeal.
On cost structure, three drivers dominate. First, transcripts, billed per page—a multi-day trial commonly produces transcript bills in the thousands of dollars. Second, the appeal book and procedural compliance. Third, and largest, the factum: appeals are won on the written argument, and the disciplined distillation of a trial record into 30 pages of legal error is where appellate counsel earn their fee. Oral argument matters, but it is the factum that frames the panel's thinking before anyone stands up.
Ontario's loser-pays principle applies on appeal: an unsuccessful appellant typically contributes to the respondent's appellate fees on a partial indemnity basis, commonly in the range of 40–60% of actual fees. In our own reported appellate matters, costs awards have ranged from $6,000 on a Small Claims appeal to $15,000 on a Divisional Court construction lien appeal.

Why Most Appeals Fail—and Honest Case Selection
Most civil appeals are dismissed, and the reason is structural, not bad lawyering. The system assigns fact-finding to the trial judge and error-correction to the appellate court. Deference on facts and credibility is the default; correctness review is the exception. An appeal whose real complaint is “the judge believed the wrong witness” or “the damages are too high” is arguing against the standard of review itself, and the standard almost always wins.
The appeals that succeed share a profile: a specific, extricable legal error—the wrong test stated or applied, a statutory provision overlooked, a material misapprehension of evidence, a denial of procedural fairness—that demonstrably affected the result. Identifying that profile before filing is the core skill of appellate case selection.
Our firm has argued at the Court of Appeal for Ontario and the Divisional Court for over 30 years, on both sides of the appellate bench—prosecuting appeals and defending judgments we won at trial, including Wei v. Ye-Hang Canada, 2026 ONCA 180 and Atlas (Brampton) v. Canada Grace Park, 2021 ONCA 221. Our reported decisions are searchable on CanLII.
That experience produces one consistent piece of advice: get a cold merits assessment before committing fees. Sometimes the most useful advice an appellate lawyer can give is “do not appeal”—settle, comply, or redirect the money to the next dispute. When the grounds are real, we say so and build the factum accordingly. Details of how we run appeals are on our Toronto appeal lawyer page.
Frequently Asked Questions
How long do I have to appeal a court decision in Ontario?
For most final orders of the Ontario Superior Court, you must serve a notice of appeal within 30 days of the date of the order (Rule 61.04 of the Rules of Civil Procedure). Where leave to appeal an interlocutory order is required, the notice of motion for leave must be served within 15 days. Missing the deadline means bringing a motion to extend time, which is granted only on specific factors — including an intention to appeal formed within the 30 days, the explanation for the delay, prejudice to the other side, and the merits of the proposed appeal.
What is the difference between the Court of Appeal and the Divisional Court?
The Court of Appeal for Ontario hears appeals from final orders of the Superior Court where more than $50,000, exclusive of costs, is at stake. The Divisional Court hears appeals from final orders of $50,000 or less, interlocutory orders (with leave), Small Claims Court appeals, judicial review applications, and statutory appeals from most tribunals, including the Landlord and Tenant Board. Filing in the wrong court wastes months and can be fatal to the appeal.
Does filing an appeal stop the other side from enforcing the judgment?
Partially. Under Rule 63.01 of the Rules of Civil Procedure, delivering a notice of appeal automatically stays any provision of the order that requires the payment of money, other than support. Non-monetary orders — injunctions, orders for possession, specific performance — are not automatically stayed. To suspend those, the appellant must bring a motion under Rule 63.02 and satisfy the three-part test from RJR-MacDonald v. Canada: a serious issue to be tried, irreparable harm, and a balance of convenience favouring a stay.
Can I introduce new evidence on appeal?
Rarely. An appeal is decided on the trial record. Fresh evidence is admitted only where it could not have been obtained with due diligence for trial, is relevant and credible, and could reasonably have affected the result — the test derived from Palmer v. The Queen. If the complaint is that important evidence was never put before the trial judge, the realistic question is why, and the answer usually defeats the fresh evidence motion.
How long does a civil appeal take in Ontario?
From notice of appeal to a decision, a typical civil appeal at the Court of Appeal for Ontario takes roughly a year, and sometimes longer where trial transcripts are extensive. The appellant must order transcripts, then perfect the appeal — file the appeal book, transcripts, and factum — before a hearing date is assigned. Divisional Court appeals follow a comparable arc. Judgment is often reserved after the hearing and released weeks or months later.
How much does an appeal cost in Ontario?
The main cost drivers are transcripts (billed per page, often thousands of dollars for a multi-day trial), preparation of the appeal book, and — above all — the factum, which is where an appeal is won or lost and where most lawyer time is spent. Ontario's loser-pays rule applies on appeal: an unsuccessful appellant typically pays a portion of the respondent's appellate legal fees, usually assessed on a partial indemnity basis of roughly 40–60%. Appellants can also be ordered to post security for costs under Rule 61.06.
What are the chances of winning a civil appeal?
Most civil appeals are dismissed. Appellate courts defer to trial judges on findings of fact and credibility, intervening only for an error of law or a palpable and overriding factual error. An appeal framed as 'the judge got the facts wrong' rarely succeeds. The appeals that win identify a specific, extricable legal error that actually affected the outcome — which is why honest case selection before filing matters more than anything argued at the hearing.
