Things are changing constantly and the Canadians are currently unhappy with a bunch of folks that failed to follow their rules...
If things are back to normal by then you can simply drive up. Fill out the proper paperwork ahead of time and you will be fine. Except...
Magazine limits for most long guns 5 and most handguns is 10. They will take them away from you.
Ammo is limited by weight per person.
To avoid hassles you may mail long guns ahead of you, from yourself, to yourself. You are required to open the package on the other end.
Handguns my be shipped the same way, but you cannot mail them, you have to use a "common carrier" such as UPS. They have their own rules about using overnight and such, but those are not law, just their rules.
