Also have a back-up plan in case the border agent decides to not approve your form. This is possible. If this happens, you will need to leave your weapon in the USA, so have a plan of what you will do.

This sounds like a double edge sword - you might get the gun into Canada the first time but not the second time from Alaska. Or you might be OK for both entries.

As well, it is valid for only 60 days. So if you will re-enter then exit Canada more than 60 days after you first entered Canada, you must either get it renewed before it expires or apply for a new one when you cross into Canada.

The RCMP website advises:
Once the declaration has been confirmed by the CBSA customs officer, it acts as a licence for the owner and it is valid for 60 days. The declaration can be renewed for free, providing it is renewed before it expires, by contacting the Chief Firearms Officer (call 1-800-731-4000) of the relevant province or territory.

I don't know which CFO you should phone if you first entered in B.C. and then plan to re-enter Canada at a Yukon crossing. Do you phone Yukon's CFO or B.C.'s?

I do know the Beaver Creek customs agents are well-known for their diligence. So do be sure your paperwork is in order.
