Are Radar Detectors Legal in Canada? A Province-by-Province Guide
Personal use is permitted in British Columbia, Alberta and Saskatchewan, but Saskatchewan prohibits detectors in commercial vehicles. They are prohibited elsewhere in Canada.
Where detectors are prohibited
Ontario, Quebec, Manitoba, Nova Scotia, New Brunswick, Prince Edward Island, Newfoundland and Labrador, Yukon, Northwest Territories and Nunavut prohibit radar detectors in vehicles; some laws also cover possession.
Travelling between provinces
A detector legal in one province may become prohibited at a border. Do not carry it in a vehicle through a prohibited jurisdiction; check official law for commercial travel.
Radar detector versus camera-alert app
A phone app reporting mapped cameras is not necessarily treated the same as hardware, but device and distracted-driving rules still apply. Check current provincial law.
Prioritise compliance
A detector or app does not change the posted limit, prevent a citation or guarantee advance notice. Drive within the limit and follow road conditions.
