OH BOY!! YOU WOULD HAVE TO ASK!!. I don't think their would be any problems coming in but one time when I went to Canada, they searched our car at the border and I had a monster Bowie knife packed in the trunk. The border guy had a fit. He demanded to know why anyone would need a knife that big. They held us up for about an hour while the combed through our records on their computer. After about an hour I got TEE"D off and said, "Is that Damn knife illegal or Not?" He said well, No but, And I said,"Either turn us back or let us go through, I am done screwing with you" He let us pass through but what a deal.
That said, I have been across the Canada border about 28 times to hunt and fish and that was the only time we ever had a Problem. One thing though, if you have any prescription Medicines, be sure they are in the original bottle, they can be fussy about that on both sides. I would call ahead to whatever port of entry that you plan to use and ask a few questions. I know a guy who lost a rifle there and never got it back.
