My Car was also in Canada , and I took it back to the US to cross it over with the stamped title after they had it at the US office for the 72 hours.
It would be great if you did not have to back to the border with the car.
I called several times to the crossing , and each time I was given the same information. I had to send the title Fedex at least 72 hours in advance, and I had to pick it up at that US crossing , and then bring the car back into Canadan to be able to register it here.
I wish you the best, I would have preferred not to have taken the drive back also.
Maybe you can find another solution.
