Voir Dire Explained for Ontario Jurors
Know the questions, your rights, and the best ways to stay calm during jury selection.
If the words voir dire make you picture an intense courtroom cross-examination, relax: it is simply the question-and-answer stage of Ontario’s jury selection. Lawyers and the judge ask prospective jurors brief, targeted questions to confirm impartiality and eligibility. You are not on trial—your honesty is all that counts. This guide demystifies the process, shows example questions, outlines your legal rights, and shares proven techniques to keep nerves in check so you can serve with confidence.
What Is Voir Dire?
Origin
The term comes from Norman French—literally “to speak the truth.” Adopted by English common-law courts in the 14th century, it travelled to Canada with British colonial rule. Modern Ontario courts retain the practice to ensure that every juror who takes the oath can weigh evidence fairly, free from bias or outside influence.
Legal Purpose
Under the Criminal Code s. 638 and Ontario’s Juries Act, lawyers may challenge a prospective juror for cause—asking specific questions about bias—or use a limited number of peremptory challenges (reasons not required). The judge supervises to keep questions relevant and respectful. Answers help the court decide whether to excuse a juror, not to judge character or intelligence.
Jury Impact
Honest replies shape the final 12-person panel but do not sway the trial’s outcome. If you disclose a bias and are excused, you have fulfilled your legal duty by being truthful. If you remain on the panel, the process affirms your impartiality. Either way, voir dire strengthens the fairness of Ontario’s jury system.
