Reading Topic: Radar detectors
Nah...they're probably OK. Even Valentine1 hasn't had a hardware update in a long time. If they are illegal in Canada then the older detector stealth might not be good enough for you.
The newest risk on the way is the POP radar gun stealth mode. No detector has a good repeatable detection of that. But read up on the stealth mode and you'll find out that they can't actually prosecute a ticket based solely on a stealth speed reading (because it's not as accurate).
The best thing to do about a detector is buy a Valentine. Sure, it's $400, but in 4-5 years you can sell it on Ebay for $325-350. Pretty cheap to have the best for 5 years for $50-75.
Just my two cents.
