I was heading to Toronto yesterday and happened to see a vehicle pass me with his radar detector mounted to his front window. He was from Pensylvania and I don't know if dectors are legal there and perhaps he was unaware that radar detectors are illegal thoughout Canada. Here you lose the detector and get fined so for those who use one...( I take the 5th)...hide it. In Ontario there are 3 OPP cruisers (maybe more now) that have detection devices that can alert them of a radar dector in your vehicle even if it's a passive dectector. Those detection devices cost around $80,000 so you know there's not too many cruisers with them.
