Purchasing a Sailplane in Canada

I am about to buy a ship in Canada and bring it into the US.
Compounding the fact that it is my first sailplane purchase is that I
have never been to Canada, let alone bought anything there. The owner
has a valid C of A issued by Transport Canada, the original export C of
A for the glider to Canada, all inspections and service history records
since the glider arrived in Canada, and a current flight manual.
Could folks from the forum please share their experiences and knowledge
regarding this process? Anything from what to do before leaving
(ship/trailer licensing, insurances, etc.); what to bring, or not to
bring, to pickup the ship; changing funds from US to Canadian dollars;
what to expect bringing the ship back into the US; any "I wish I had
done it this way" experiences.

If you can provide the links to any existing "how-tos", that would
be great. Thanks for your help.
