I've used Borderview both ways and always find them slow. Your experience is not out of the ordinary. On the plus for imports to the US they are quite careful about the size and placement of the engraving of the importers name that must be applied to the gun.
I have also used IRUNGUNS to import into the US. They were reasonably quick in comparison but sloppy on the engraving. I'll take slow over irreparably changing the gun with an engraving that is crude and poorly positioned. Cost was about the same.
HOWEVER for exports from the US/imports to Canada, the people to use are Prophet River in Lloydminster, Sask. Fast, hands on and cheap from one of the most respected gun dealers in Canada. By cheap I mean 1/3 the price. By fast I mean I bought a gun last summer from Pete Hiatt. From the time Pete put it in the USPS, was under 3 weeks to my door. That included shipping to the US based FFL, clearing customs, and then shipping across the continent to me in Ontario.
Too late for you now but next time, don't bother with anyone else for exports to Canada.
