Which Canadian provinces allow radar detectors?

Alberta, British Columbia, Saskatchewan and the three territories permit radar detectors in private passenger vehicles. Ontario, Quebec, Manitoba, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador prohibit them.

Can police seize a radar detector in Ontario?

Yes. In provinces where detectors are prohibited, police can issue a fine and confiscate the device, and in some cases the device is not returned.

Is it illegal to carry a switched-off detector in a banned province?

In several prohibiting provinces, including Quebec, simply having the device in the vehicle is an offence regardless of whether it is powered on. Store it out of the vehicle when crossing into those provinces.

Crossing provincial borders

Driving from Alberta into Manitoba or from BC across the country means your detector goes from legal to seizable at the border.
Unplug and store the device outside the cabin — a boot or trunk — before entering a prohibiting province.
Suction-cup marks on a windscreen have been used as grounds for a search in prohibiting provinces; remove the mount too.
Commercial vehicles face additional restrictions on both sides of the Canada–US border.

Detectors vs jammers in Canada

Laser jammers are treated far more seriously than detectors and are prohibited in provinces that ban detectors as well as regulated federally as radio-transmitting equipment. McFlash is receive-only — see detectors vs jammers.
