There's something called the interprovincial record exchange. It's managed by the CCMTA. I think you are actually seeing provincial governments step up and use the IRE more. It was one of the recommendations in the national action plan on combatting auto theft.
I'm encouraged by what I've seen, which is a real focus on improving the data. The problem with a national VIN registry or an IRE is that it's garbage data in, garbage data out.
