The minimum penalty for an offence against the law is CAD25. Parents are responsible for offences committed by children under 16 years if aware that the child did not wear a helmet. In addition, a peace officer may seize and detain for 30 days the bicycle of a person not wearing a helmet.

Relative to cycle use (see below), the law did not change the number of head injuries but the total number of cycling injuries doubled.
Post-law cycle use fell by 40% to 60%, with the largest decrease among teenagers. The rise in the number of people wearing helmets was less than the fall in cyclists in the two years following the law (Chipman, 2002).
