I hear that the rcmp has been continuously adding guns to the prohibited list. There were a bunch of callers on the Danielle Smith show bringing up the issue. That does sound shady to me and I don't doubt that they're doing it. There are a few, let's say, not peer reviewed websites, mentioning it too.

Looks like more shotguns are getting the axe now.
