Savage has great support in Canada. My buddy had a barrel issue with his 17HMR, he called Savage had quick turn around and they threw in a spare magazine.
Or you can just order a upgrade kit online and replace it yourself if you are okay with working on guns. Be warned, the detent is under extreme pressure and will take off flying if you are not careful. For the record this is my second rifle make with this type of problem, but at least they don't fire by themselves.

The Savage FV is a great gun, enjoy it and make sure you leave your targets out so naysayers can stare at them.
