I've crossed the border at least 7 times with guns and never had any issues with the Canadian side. Only issue I've had was getting an anti-hunting bitch on the US side who made it difficult bring my meat across. Several of the US agents came up to me in her presence and apologized for her. Every other time it has been a good experience. The Canadians always seem to be more worried about how much beer I have than my guns.
I didn't have an problems getting my rifle across- my problems were just getting through immigration BEFORE I could even process my gun permit. The guy was a total jerk. Didn't have any problems with the US side- just showed the guy my DOJ creds and he waved me through!
