Radar Detector Canadian Buyer's Guide and FAQ - KMPH.ca , you can beat it in BC court if you end up there as long as the jammer is also used as a parking sensor, most now have this feature. There was a thread over at bcsb about this , it can be a hassle but it is not illegal, but for those with lead foots it can really help
I had looked at a jammer at one time for my car G9 model , damn nice but costly and you need a nice stealth install, I know an individual using one and it works well in conjunction with radar in his AMG C63. The site I have linked is a local site selling some of the best radar equipment in Canada and they are BC based.
