A plain-language explanation of good character, prior convictions, similar-fact evidence and safeguards against unfair prejudice.

Character evidence in a criminal trial in Canada covers several related but distinct rules. Evidence about reputation, personal traits, prior convictions or other alleged conduct is not automatically admissible. Its use depends on why it is offered, what issue it addresses and whether its value outweighs unfair prejudice. This article provides general education, not advice about a particular case.

What this issue means

Character evidence is evidence offered to say something about a person’s disposition, traits or reputation. The concern is often whether a court may reason from that material that the person was more or less likely to have acted in a particular way.

Canadian criminal trials do not decide whether an accused is generally a good or bad person. They decide whether the Crown has proven every essential element of a specific charge beyond a reasonable doubt using admissible evidence. An allegation is a claim that something occurred. A charge is a formal accusation. Neither is a finding or conviction.

As a general principle, the Crown cannot introduce evidence merely to show that the accused has a bad character or a tendency to commit crimes and therefore probably committed the offence charged. This kind of propensity reasoning can create:

  • Moral prejudice: the risk that the decision-maker will dislike or condemn the accused and punish the person for past conduct or perceived character.
  • Reasoning prejudice: the risk that the trial will be distracted by side issues, consume excessive time or become difficult to decide fairly.

Evidence that appears to reflect character may be admissible for another legally relevant purpose. Courts examine why the evidence is offered and how it may be used.

What may happen next

Character-related issues may arise before or during trial. Counsel may ask the judge whether proposed evidence is admissible and how it may be used. The judge may hear arguments without the jury present.

Possible outcomes include:

  • The evidence is excluded.
  • Only part of the evidence is admitted.
  • References are edited or limited to reduce unfair prejudice.
  • The evidence is admitted for one purpose but not another.
  • The judge gives a limiting instruction explaining the permitted and prohibited uses.

The process depends on the type of evidence, the offence, whether the accused testifies, the issues at trial and whether the matter is heard by a judge alone or by a jury. Court practices may also vary by province or territory.

Character evidence in a criminal trial in Canada: key distinctions

Evidence of good character

An accused may choose to place good character in issue. Depending on the circumstances, a relevant trait may support an inference about conduct or credibility.

That choice can have consequences. Section 666 of the Criminal Code states that when an accused adduces evidence of good character, the prosecutor may answer with evidence of the accused’s previous convictions. Other forms of response may also depend on the evidence and applicable common-law rules.

Not every favourable fact is good-character evidence. Whether testimony or a reference places character in issue is technical and case-specific. A criminal lawyer can explain the possible effects.

Prior convictions when the accused testifies

If an accused testifies, the accused becomes a witness. Section 12 of the Canada Evidence Act permits a witness to be questioned about prior convictions, subject to the trial judge’s discretion to prevent unfairness.

The Supreme Court of Canada confirmed in R. v. Hussein, 2026 SCC 2, that an accused’s criminal record admitted under section 12 is character evidence used for the limited purpose of assessing credibility. It cannot be used simply to reason that the accused committed the charged offence because the accused committed offences before.

A judge may exclude all or part of a record where unfair prejudice outweighs its legitimate value. The nature, age and similarity of convictions can matter. A jury should receive instructions about the record’s limited use.

Similar-fact evidence

Similar-fact evidence usually concerns other alleged acts that are not part of the charge being tried. It is presumptively inadmissible when offered only to show that the accused is the kind of person likely to commit the offence.

In R. v. Handy, 2002 SCC 56, the Supreme Court of Canada explained that the Crown must show that the probative value of proposed similar-fact evidence on a specific issue outweighs its prejudicial effect. Depending on the case, a specific issue might include identity or whether apparently innocent conduct was accidental. The rule is demanding because of the risk of propensity reasoning and a trial becoming focused on collateral events.

Shared features between two events do not automatically make similar-fact evidence admissible.

Evidence about a complainant or another witness

Ordinary credibility evidence is not necessarily character evidence. For example, a prior inconsistent statement may be relevant to whether a witness’s testimony is reliable without inviting a conclusion about that witness’s general worth as a person.

Special statutory protections apply in prosecutions for listed sexual offences. Section 276 of the Criminal Code prohibits using a complainant’s other sexual activity to infer that the complainant was more likely to have consented or is less worthy of belief. Other sexual-activity evidence may be admitted only through the statutory process and only if its specific relevance and probative value satisfy the legal test. Section 277 makes sexual reputation evidence inadmissible to support or challenge the complainant’s credibility.

These restrictions guard against myths and stereotypes. They do not determine whether an allegation is true; the trier of fact must assess the admissible evidence and apply the burden of proof.

Trial evidence and sentencing material are different

Character letters and community references are more commonly associated with sentencing after a guilty plea or conviction. Sentencing serves a different purpose. A letter considered at sentencing is not automatically admissible at trial.

Important educational considerations

Relevance does not guarantee admissibility

Evidence can have some logical relevance and still be excluded because of a legal rule, unfair prejudice, confusion, delay or another concern. The judge’s task is not simply to ask whether the evidence is interesting or unfavourable.

Purpose controls use

The same information may be admissible for one purpose and prohibited for another. A prior conviction admitted to assess a testifying accused’s credibility is not proof that the accused committed the current offence. A limiting instruction is intended to preserve that boundary.

Evidence of conduct is not always character evidence

Evidence connected to the charged event may help prove an element, provide context or support a specific inference. Calling every unfavourable fact “character evidence” can obscure the legal question.

The presumption of innocence remains

An accused does not lose the presumption of innocence because the court hears admissible character-related evidence. The Crown must still prove every essential element beyond a reasonable doubt. An acquittal means the Crown did not prove guilt to that standard; it is not a judicial declaration that every allegation was fabricated. A withdrawal, dismissal and acquittal arise through different processes and should not be treated as interchangeable.

Practical steps that are general and non-legal in nature

Someone trying to understand a character-evidence issue can take general organizational steps:

  • Keep court documents, disclosure and correspondence organized in a secure place.
  • Write down questions for a lawyer, including what evidence is proposed, who may introduce it and for what stated purpose.
  • Record court dates and filing deadlines exactly as provided by the court or counsel.
  • Avoid posting about the allegation, witnesses or evidence on social media.
  • Preserve existing records without altering, deleting or circulating them.
  • Use official Canadian legal information and note the jurisdiction and publication date.
  • Ask a lawyer before obtaining or distributing character letters for use in a proceeding.

These steps do not replace legal advice. Evidence rules are technical, and apparently helpful actions may have unexpected consequences.

Emotional and family impact

Learning that personal history, reputation or past convictions may be discussed in court can cause shame, fear, anger or a sense of lost control. Family members may also feel pressure to defend the accused publicly or contact people connected with the case.

It may help to separate emotional support from legal decisions. A trusted person can assist with meals, transportation, childcare or scheduling without contacting witnesses or discussing evidence. Confidential support from a regulated mental-health professional may also be appropriate. For an immediate safety concern, contact local emergency or crisis services.

When professional assistance may be appropriate

A criminal defence lawyer can advise whether proposed evidence is character evidence, whether an application is required and how a ruling affects the trial. This requires the actual charge, disclosure, procedural history and law.

People who cannot afford private counsel may check legal aid, law-society referral or duty counsel resources in their province or territory. Eligibility varies. Court staff can provide administrative information but not legal advice.

How Presumption of Innocence Canada may help

Presumption of Innocence Canada (PIC) is a volunteer-run Canadian not-for-profit organization focused on public legal education. It provides plain-language educational resources and moderated online discussion groups for Canadian residents aged 18 and older. PIC describes its discussion groups as educational spaces and draws its materials from public legislation, court decisions, government publications, Statistics Canada and peer-reviewed research.

PIC does not provide legal advice, legal representation, case-specific guidance or legal strategy. It does not determine whether an allegation is true or whether a person is innocent, and it does not advocate for a particular case outcome or changes to the law. Its educational resources and discussion groups may help readers learn terminology, organize questions and locate reliable public information before speaking with a qualified lawyer.

Frequently Asked Questions

1. What is character evidence in a criminal trial in Canada?

It is evidence offered to say something about a person’s disposition, traits or reputation, often to support an inference about conduct or credibility. Whether it is admissible depends on its purpose, the issue it addresses and the risk of unfair prejudice.

2. Can the Crown tell the court that the accused is a bad person?

Not simply to invite the conclusion that a person with bad character probably committed the charged offence. Evidence that has another specific and legally permissible purpose may be considered under the applicable admissibility rules.

3. Can an accused call evidence of good character?

Sometimes, but doing so may allow a response from the Crown. Section 666 of the Criminal Code permits evidence of previous convictions in answer when the accused adduces evidence of good character. Legal advice is important before deciding whether to place character in issue.

4. Does a prior conviction prove guilt on a new charge?

No. When an accused testifies, a prior conviction may sometimes be admitted for the limited purpose of assessing credibility. It cannot be used merely to reason that past offending proves the current charge.

5. What is a Corbett application?

It is a request by a testifying accused for the trial judge to exclude or limit the use of prior convictions because their unfair prejudicial effect outweighs their value for assessing credibility. The name comes from the Supreme Court of Canada’s decision in R. v. Corbett.

6. Is similar-fact evidence the same as a criminal record?

No. Similar-fact evidence concerns other alleged acts said to be probative of a specific issue. A criminal record lists convictions. Different rules govern their admission and use, although both can raise concerns about prohibited propensity reasoning.

7. Can a complainant’s sexual history be used to challenge credibility?

Sexual reputation evidence cannot be used to support or challenge credibility in prosecutions for listed sexual offences. The Criminal Code also prohibits the two “twin-myth” inferences and requires a statutory application before other sexual-activity evidence may be admitted for a permitted purpose.

8. Are character letters evidence at trial?

Not automatically. Character letters are often associated with sentencing, which occurs only after a guilty plea or conviction. Trial admissibility is a separate question governed by evidence rules.

9. Do the rules differ across Canada?

The Criminal Code, Canada Evidence Act and Supreme Court of Canada decisions apply nationally, but provincial or territorial evidence legislation, court rules, legal-aid services and local procedures may also matter. A lawyer in the relevant jurisdiction can advise on the specific proceeding.

Conclusion

Character evidence in a criminal trial in Canada is governed by rules designed to keep the decision focused on admissible evidence and prevent unfair reasoning about a person’s general character. Good-character evidence, prior convictions, similar-fact evidence and sexual-history restrictions are related topics, but they are not interchangeable. Because admissibility depends on purpose and context, anyone facing a criminal proceeding should obtain advice from a qualified lawyer about their circumstances.
