Sorry, I should also add that most gunsmiths will store your firearm for about $1 a day. Maybe some small stores will store it for free for a month or so, if you make a sizable purchase.
Another thing is ammo. Shipping ammo is a problem, hazmat. Transporting ammo for a gun you do not have is a problem in Canada. Buy your ammo in Alaska. I was even thinking of taking components and rolling my own in Alaska. Some say this is easier for Canadian customs.
I gave up, and will take a rifle instead. This will be a practice run for a Canadian moose hunt with my son in 2019.
