Oddly enough, some time ago there was a Senate bill, Bill S-8, which actually set a target of 25%. I don't believe the government has ever achieved that. From what we can determine, from department to department there is no coordinated approach. if you've got 20,000 vehicles out there that are purchased every year, yes, it's high volume. Think of how many more vehicles and how much pull you could create if government departments, municipal governments, and provincial governments actually coordinated that.
