Wildlife Violator Compact.......Why not here??

I just heard about this program States side.

Why don't the Canadian Provinces join this program.
Not only Province to Province but tie it in with the participating US States.

I reccommended this for the Saskatchewan Wildlife Federation a couple of years ago. There was very little interest in pushing for it, and it was voted down at the convention.
