I haven't heard of any exemptions, but I can't say for sure. I'm pretty confident there wouldn't be any for permit holders since there really isn't an equivalent up here (handguns can be transported, locked up, to & from an approved range and that's about it with very few exceptions).

That said, I'm not a firearms licence holder & don't have any firearms myself so I'm likely not the most versed on all the regulations. That said, from the earlier link, non-restricted firearms (rifles (not an AR), shotguns) seem a lot easier to bring into the country than restricted ones (like handguns).
