Appealing a sentence in Ontario: start with the deadline

Appeal a sentence in Ontario by asking the appropriate appeal court to review a legal or sentencing error; it is not a fresh sentencing hearing where everything starts again. Deadlines can be short, the correct form and court depend on the route of appeal, and prompt advice is important before a filing date passes.

In order to appeal a sentence, the first step is to file a form called a “Notice of Appeal.” In a Notice of Appeal, you must state what you are appealing, such as a conviction, sentence or both, and in addition, explain the mistakes that you believe were made during the trial. The Notice of Appeal must be filed within 30 days. Judges may allow an appeal against a conviction only if they are satisfied about the following: 1) The conviction at trial was unreasonable, 2) The trial court made a mistake with respect to the law, 3) There was a miscarriage of justice

The quote identifies the essential urgency, but a sentence-only appeal may challenge the sentencing judge’s approach rather than a mistake at trial. Appeal deadlines are commonly measured from the decision being challenged, but the applicable rules, event that starts the clock, form, and possibility of an extension should be confirmed for the particular case immediately.

A person considering an appeal should keep the endorsement, reasons for sentence, probation order, victim fine surcharge information, DNA order, driving prohibition, and every document received in court. These materials can matter as much as the length of custody or amount of a fine. The practice areas of jeffrey i reisman include criminal-defence matters where early procedural advice may be needed.

What is a criminal appeal?

A criminal appeal is a review by a higher court of a conviction, sentence, or both, based principally on the record created in the lower court. It is not normally a second trial with new witnesses or a new opportunity to make a different case simply because the result was disappointing.

An appeal of a conviction asks whether the guilty finding should stand. An appeal of a sentence accepts, at least for the purpose of that appeal, that there was a conviction but argues that the penalty was reached through a reviewable error or falls outside the acceptable range.

The distinction matters. Someone convicted after a trial might appeal the conviction because the judge applied the wrong legal test to identification evidence. Another person who pleaded guilty may have no trial issue but may seek to appeal a jail sentence because the sentencing judge overlooked a significant mitigating circumstance or applied a wrong legal principle.

For indictable matters, the Criminal Code provides appeal rights, including under section 675 of the Criminal Code. Whether an appeal is available as of right or requires leave to appeal depends on what is being challenged and the ground advanced.

Which court hears a criminal appeal in Ontario?

In Ontario, appeals in indictable criminal cases are generally heard by the Court of Appeal for Ontario. That court hears appeals from convictions and sentences imposed in the Superior Court of Justice and, in the usual indictable route, from the Ontario Court of Justice.

Summary conviction appeals generally go first to the Superior Court of Justice rather than the Court of Appeal for Ontario. The appeal structure, forms, and further appeal rights differ from indictable proceedings, so a person should identify whether the charge proceeded summarily or by indictment before filing anything.

The Criminal Code addresses summary conviction appeals in section 813 of the Criminal Code. A conviction for a summary offence can have serious employment, immigration, travel, licence, and family consequences even where the sentence appears modest; the appeal route should not be assumed from the label of the offence alone.

For example, consider someone convicted of assault after a provincial-court trial that proceeded summarily and sentenced to a fine and probation. Their first appeal would ordinarily follow the summary conviction appeal route to the Superior Court of Justice. A person convicted of an indictable robbery offence would generally have a different route to the Court of Appeal for Ontario.

Grounds for appealing a sentence

A sentence appeal needs an arguable reviewable error, such as an error in principle that affected the sentence or a sentence that is demonstrably unfit. Mere disagreement with a judge’s choice of sentence is usually not enough because appeal courts give substantial deference to sentencing judges.

An error in principle can include relying on an irrelevant factor, failing to give effect to a relevant legal principle, double-counting an aggravating feature, misapplying a mandatory statutory requirement, or giving inadequate reasons in a way that prevents meaningful appellate review. The important question is not simply whether another judge might have imposed a different sentence; it is whether the error affected the result or the sentence falls outside the acceptable range for the offence and offender.

Consider a person with no record who pleads guilty to fraud involving $18,000 taken from an employer, makes meaningful restitution before sentencing, and has documented treatment for a gambling disorder. If the sentencing reasons do not address the guilty plea, restitution, rehabilitation evidence, or the principle of parity with comparable cases, counsel may assess whether there is an arguable sentencing error. That does not mean the appeal will succeed or that custody is unavailable; fraud involving a breach of trust is treated seriously.

Sentencing in Canada is governed by the Criminal Code, applicable statutes, and appellate case law, not by a general American-style sentencing-guideline system. The sentencing purposes and principles in section 718 and following provisions of the Criminal Code often shape the arguments made at sentencing and on a sentence appeal.

Grounds for appealing a criminal conviction

A conviction appeal may argue that the verdict was unreasonable, that the trial judge made a legal error, or that there was a miscarriage of justice. These categories overlap at times, but each requires careful review of what happened at trial and why it may have affected the verdict.

An unreasonable-verdict argument is not an invitation for the appeal court to substitute its own view of every witness. It asks whether the verdict can reasonably be supported by the evidence when the record is properly reviewed. A legal-error argument may concern the elements of the offence, the burden of proof, admissibility of evidence, jury instructions, or a ruling on a Charter issue.

A miscarriage of justice may arise from a serious procedural unfairness or an error that undermines confidence in the reliability or fairness of the result. Allegations involving late disclosure, a breach of the Canadian Charter of Rights and Freedoms, or ineffective assistance of counsel are fact-specific and should be raised carefully. They can require affidavits, motions, and a focused analysis of what occurred, rather than a general assertion that counsel did not do enough.

For example, consider someone convicted after a jury trial where the central issue was whether the accused was the person seen in poor-quality surveillance video. If the trial judge gave the jury a legally incorrect instruction about identification evidence, the transcripts, charge to the jury, objections, and closing submissions would be central to assessing an appeal. The appeal court would examine the record; it would not ordinarily hear the case again from the beginning.

How to start an appeal and protect your deadline

To start an appeal, identify the decision and appeal route, preserve the deadline, and obtain the documents needed to assess the grounds. Do not wait for a complete legal opinion before taking steps to protect a filing deadline where time is running out.

1. Get the court details. Record the date of conviction, sentencing date, court location, judge’s name, charge, sentence, and any ancillary orders.
2. Identify what is being appealed. Decide whether the concern is the conviction, sentence, or both, and whether the case proceeded summarily or by indictment.
3. Act on the Notice of Appeal promptly. Obtain urgent advice about the correct notice, court office, service requirements, and deadline before it expires.
4. Preserve the record. Keep disclosure, trial exhibits where available, reasons, endorsements, transcripts already obtained, sentencing briefs, character letters, medical reports, and correspondence with prior counsel.
5. Ask about an extension if necessary. An extension may be possible in some circumstances, but it is discretionary and should not be treated as a substitute for filing on time.

The notice generally identifies the decision under appeal and the proposed grounds at a high level. Grounds can sometimes be refined once transcripts and the record are reviewed, but a person should not use vague or improvised paperwork as a substitute for legal advice.

What happens after a Notice of Appeal is filed?

After a Notice of Appeal is filed, the usual process is to assemble the appeal record, obtain transcripts, exchange written arguments called factums, and attend an oral hearing. The exact steps and timing vary with the court, the type of appeal, the issues, and any motions required.

Transcripts are often essential because an appeal court needs to know precisely what witnesses said, what objections were made, what the judge ruled, and what reasons were given. The appellant’s factum sets out the facts, legal issues, argument, and remedy sought. The Crown files a responding factum, and the appellant may have a limited opportunity to reply.

At the hearing, appeal judges usually focus their questions on the legal issues and the record. New evidence is exceptional, not routine. A person appealing should retain all sentencing materials, reasons, relevant exhibits, and communications that may help counsel reconstruct the procedural history.

Criminal appeal rules are technical. If the original proceeding involved a guilty plea, a self-represented trial, an application to exclude evidence, or a contested sentencing hearing, the appeal record may need special attention to ensure the relevant material is before the court.

How long does a criminal appeal take in Ontario?

How long an appeal takes in Canada or Ontario varies materially; transcript preparation, record length, motions, court scheduling, and the complexity of the issues all affect timing. There is no responsible standard duration that applies to every criminal appeal.

A brief sentence appeal based on a narrow legal issue may move differently from a multi-week trial appeal involving numerous witnesses, disclosure issues, and constitutional arguments. Requests for extensions, disputes over transcripts, fresh-evidence motions, and changes in counsel can also add time.

A person in custody should seek advice without delay about preserving the appeal, surrender requirements, and bail pending appeal. A person facing collateral consequences, such as an immigration proceeding, employment discipline, a professional-licensing issue, or a driving prohibition, should provide the relevant deadlines and documents to counsel early so they can be considered in planning the appeal.

What are the odds of winning an appeal?

No responsible lawyer can give reliable odds of winning an appeal without reviewing the record, reasons, and applicable law. Appellate courts defer to trial-level fact-finding and sentencing discretion, so an appeal requires more than a belief that the original judge reached a harsh or incorrect result.

A useful merits review asks:

• What exactly did the judge decide, and what reasons were given?
• Is there an identifiable legal error, unreasonable finding, procedural unfairness, or sentencing error?
• Did the alleged error affect the verdict or sentence?
• Was the issue raised or preserved at trial or sentencing, and if not, why not?
• What remedy is legally available and practically useful?

For a sentence appeal, the reasons for sentence, comparable decisions, pre-sentence material, and submissions made in court may be more important than a general account of personal hardship. For a conviction appeal, trial transcripts, evidentiary rulings, and the judge’s instructions or reasons usually require close review.

What can the appeal court do?

An appeal court can dismiss an appeal, vary a sentence, order a new trial, or enter an acquittal where the law and record justify that result. The proper remedy depends on the type of error and whether the error can be cured without another trial.

On a sentence appeal, the court may uphold the sentence, reduce or increase it where the law permits, or vary an ancillary order. On a conviction appeal, a successful legal-error argument may lead to a new trial, while an acquittal may be appropriate where the evidence cannot legally support a conviction. The remedial powers for indictable appeals are set out in section 686 of the Criminal Code.

Before choosing an appeal strategy, discuss the possible consequences, including whether the Crown has appealed the sentence or may seek to challenge it. A Crown sentence appeal or cross-appeal can create a risk that the sentence will be increased, depending on the procedure and issues involved.

Bail pending appeal and custody

A person sentenced to imprisonment may seek bail pending appeal, but release is not automatic. The court considers the governing legal test and the circumstances of the proposed appeal, so urgent preparation is important when surrender or custody is imminent.

For indictable matters, section 679 of the Criminal Code addresses judicial interim release pending appeal. The applicant may need to address whether the appeal is not frivolous, whether surrender can be ensured, and whether detention is necessary in the public interest.

For example, a person sentenced to 90 days’ imprisonment for a driving-related offence may need immediate advice about reporting to custody, filing an appeal, and whether a bail-pending-appeal application is available and appropriate. Filing a notice does not itself guarantee that the sentence is paused.

FAQ: further appeals and practical questions

Can you appeal a Supreme Court decision in Canada?

A decision of the Supreme Court of Canada is generally final within the Canadian court system. In most criminal cases, reaching that Court already requires a further appeal route and often leave to appeal; the route, deadline, and permission requirements must be checked against the decision and current rules.

Do I have to attend the appeal hearing?

Attendance requirements depend on the court, type of appeal, and whether the person is in custody or on release. Counsel can advise whether attendance is required, permitted remotely, or unnecessary, but an appellant should never assume that a hearing date can be ignored.

What makes a good appeal statement?

A useful appeal statement identifies the decision challenged, the real legal or sentencing issue, and the remedy sought without exaggeration. The strongest grounds are tied to the actual transcript, ruling, reasons, or sentencing record, not simply to a general sense that the case was unfair.

How do I appeal a court decision in Ontario?

To appeal a court decision in Ontario, first identify the type of proceeding, the court that made the decision, the order or judgment being challenged, and the applicable deadline. Criminal appeals have different routes from civil, family, and administrative appeals, so the forms and steps should be confirmed before filing.

If you are considering whether to appeal criminal case results, a review by a criminal lawyer Toronto can help identify the correct route, the documents required, and whether there is an arguable issue. This is particularly important for anyone asking, “how do I appeal a criminal conviction in Canada?” while a deadline or custody date is approaching.
