01
Is a radar detector illegal in Canada?
There is no single nationwide rule for ordinary use; provinces and territories set restrictions. In practice, detectors are permitted only in British Columbia, Alberta and Saskatchewan for non-commercial vehicles, and Saskatchewan prohibits them in commercial vehicles.
02
Where is a radar detector illegal?
Detector use is prohibited in Ontario, Quebec, Manitoba, Nova Scotia, the territories and all other provinces outside BC, Alberta and Saskatchewan. Do not install, carry or use a device in a prohibited jurisdiction.
03
What does Saskatchewan restrict?
Saskatchewan’s traffic rules prohibit driving a commercial vehicle equipped with, containing or carrying a radar warning device, and prohibit permitting a commercial vehicle to remain equipped with one. Private vehicles are treated differently.
04
Can I travel across provincial borders with one?
A device may be legal at the start of a trip and prohibited later on the route. Check every province and territory you will enter and remove the device before entering a jurisdiction where it is banned.
05
Are radar detector apps treated the same way?
Apps that report locations or community alerts are not the same hardware as a radio-frequency detector, but their use may have separate local rules. Check the current rules for both the app feature and your location.
