In Canada, a prank phone call isn't automatically illegal just because it's annoying, silly, or involves pretending to be someone else. However, certain statements and behaviours can turn a joke into a criminal or legal problem, depending on the circumstances, your intent, and the impact on the person receiving the call.
The biggest things to avoid are threats, fake emergencies, targeted harassment, and deceptive statements intended to frighten or harm someone. Canada's Criminal Code specifically addresses false information intended to alarm or injure someone, indecent telephone calls, and repeated calls made with the intent to harass
1. Threats of violence: Don’t threaten to kill, hurt, or physically attack someone or their family, even as a joke.
2. Repeated unwanted calls: Don’t keep calling someone to harass, intimidate, or upset them after they ask you to stop.
3. Fake emergencies: Don’t falsely claim someone has died, is in danger, or that a serious emergency is happening with the intent to frighten or harm the person receiving the call.
