Percentage-wise, it varies so much from jurisdiction to jurisdiction. I can quote B.C. because I've recently had some conversations with the RCMP about Operation Impact. About 90% of their vehicles that are stolen are recovered. That's attributed to your amateur auto theft. They're not stealing the cars for the cars themselves; they're stealing them for transportation or things of that nature.
In Ontario, our recovery rate is only 60%. If a vehicle is stolen from your driveway with the keys in it, it's usually found dumped somewhere else. That's a recovered automobile, and that's the work of amateurs. The remaining 40% that disappear would be the work of organized crime. So in Ontario I'd give you the split of 60-40.
