You do not need to go to the border to pick it up. Have it mailed and pick it up at your post office no need to let Scair Canada make a nickle off of you.
Find out what you want can come to Canada of if it can even leave the USA.
After this is done find a USA exporter this is the hard part the fella in Montana has no license and his Wife is waiting on hers. She isn't 100% sure if she will even get it.
If it is a true antique in the USA it makes it a slam dunk. the fella in Montana will do them he doesn't need a license.
1 get your rifle bought so you get a serial number.
2 register it in Canada.
3 get the rifle sent to your exporter.
4 get you import papers in order.
5 send the needed papers to the importer.
6 They gets the export papers and mail it to you.
7 Customs plays with it and keeps it for a while.
8 Card from your post office item has arrived and you owe $XX.XX taxes and Handling fee from Canadian Customs.
9 pay fees pick up parcel and you my friend are in the possesion of your fire arm.
Expect to waste a month doing this process from the time you start till the time she arrives.
Have done 5 firearms so far 2 rifles antique and 2 rifles antique replicas and 1 TC Contender Barrel.
Good Luck Ken.
