Ontario Radar Detector Fine: What the Law Says About Carrying a Detector

Section 79(5) of Ontario's Highway Traffic Act makes a person convicted under subsection 79(2) liable to a fine within the range set out in the statute. Check the current text for the applicable amount and any amendments.

Section 79(3) permits an officer with reasonable grounds to stop, enter and search a vehicle and seize a device found there. The statute also addresses forfeiture following conviction.

Nova Scotia’s Motor Vehicle Act separately addresses radar-warning devices. Its rules and consequences should be checked in that province’s current legislation, rather than inferred from Ontario’s fine provision.

Section 79 defines a speed measuring warning device to include equipment designed or intended to interfere with speed-measuring equipment. Whether a particular device falls within that definition depends on its function and the law’s application.
