I know Harper deferred it/stopped from implementing it when he was in power. As you say it isn't killed or stopped permanently though and is still in play and on the back burner. I honestly wonder how the Trudeau liberal government will deal with it , first instinct is they will be liberals and go with it but honestly I'm not so sure. They don't know its full scope and I don't think they know how to deal with it really , it might make them hold off on it as well instead of jumping into something they know nothing about (like politicians haven't done that before I know, I know, lol). Like you said our gun orgs and us can sure try to stave it off and MAYBE get it scrapped or back burnered for so long its ineffective.
