Seat belt legislation in Canada is left to the provinces. All provinces in Canada have primary enforcement seat belt laws, which allow a police officer to stop and ticket a driver if s/he observes a violation. Ontario was the first province to pass a law which required vehicle occupants to wear seat belts, a law that came into effect on January 1, 1976.
The laws by province
This table contains a brief summary of all seatbelt laws in Canada. This list includes only seatbelt laws, which often do not themselves apply to children; however, all provinces and territories have separate child restraint laws. A subsequent offense may be much higher.
