# What Is a Jury in Canada?
A jury is one of the most important features of the Canadian justice system. Jurors are ordinary citizens who decide whether someone accused of a serious crime is guilty or not guilty. Jury duty is one of the responsibilities of Canadian citizenship β and a reliably tested point on the citizenship exam. Here is everything you need to know.
The simple definition
A jury is a group of citizens randomly selected from the community to:
- Listen to evidence at a trial.
- Apply the law as instructed by the judge.
- Decide guilt or innocence by unanimous verdict (in criminal cases).
A criminal jury in Canada has 12 members. Civil juries in some provinces have 6, but most civil trials are decided by a judge alone.
Who can be a juror
To serve on a jury, you must:
- Be a Canadian citizen.
- Be 18 years old or older.
- Be a resident of the province.
- Be able to understand the proceedings in English or French (depending on the trial).
Some people are exempt from jury duty by law:
- Judges and lawyers
- Police officers and prison staff
- Sitting MPs, senators, and other elected officials
- Members of the Canadian Armed Forces in some cases
- People with serious criminal convictions
Permanent residents and other non-citizens cannot serve on juries β that is why jury duty is listed as a responsibility of citizenship in Discover Canada.
How jurors are selected
The selection process happens in stages:
- Provincial voter lists β names are randomly drawn from voter registers.
- Summons in the mail β selected names receive a notice to appear at court on a specific date.
- Jury panel β those who appear form a "panel" of potential jurors.
- Selection at trial β at each trial, lawyers question and challenge potential jurors. Both Crown and defence can object to specific candidates without giving a reason (a few times each β called "peremptory challenges" β though Parliament limited these in recent reforms). They can also challenge for cause if a juror seems biased.
- Final 12 β the 12 selected jurors are sworn in.
The verdict
A criminal jury must reach a unanimous verdict β all 12 must agree:
- All 12 vote guilty β conviction.
- All 12 vote not guilty β acquittal.
- Cannot agree β hung jury. A new trial may be ordered.
This unanimity rule is a high bar β it means even one juror with a reasonable doubt can prevent conviction. That is the presumption of innocence in action β see [What Does "Presumed Innocent Until Proven Guilty" Mean in Canada?](/blog/presumed-innocent-until-proven-guilty-canada).
What kinds of trials use juries
In criminal law:
- Most serious offences with a maximum sentence of 5+ years can be tried by judge alone or by judge and jury β the accused chooses.
- Murder trials typically use a jury (with some exceptions).
- Less serious offences (Crown elects "summary conviction") are tried by a judge alone.
In civil law:
- Most civil trials are decided by a judge alone.
- Some provinces allow civil juries for cases like personal injury or defamation.
- Civil juries usually have 6 members and need a majority decision.
What jurors do during a trial
A typical jury day:
- Sit and listen β jurors cannot ask questions; they take notes.
- Hear evidence β witnesses, documents, expert testimony.
- Hear closing arguments from Crown and defence.
- Receive the judge's instructions β the judge explains the relevant law.
- Deliberate β jurors retire to discuss in private. They cannot leave or contact anyone until they reach a verdict.
- Deliver the verdict β the foreperson announces "guilty" or "not guilty" in open court.
Jurors are paid a small daily allowance and their employers must give them time off.
Jury duty and citizenship
Discover Canada lists serving on a jury as one of the responsibilities of Canadian citizenship, alongside:
- Obeying the law
- Taking responsibility for yourself and your family
- Voting in elections
- Helping others in the community
- Protecting Canada's heritage and environment
See [Responsibilities of a Canadian Citizen](/blog/responsibilities-canadian-citizen-list).
Avoiding jury duty without a valid reason is a legal offence β judges can fine or hold in contempt people who fail to appear.
