FYI - You don't need a US license to do this.
You can transfer the registration to Canadian and then fly it back yourself using your own license. The FAA will issue a flight permit that's valid until you cross the border, TC will issue a flight permit that is valid from there until you reach the airport at which you'll park it until the inspection is done.
Caution on MD-RA - Be sure that anything they ask you to do is actually supported by the regulations. 406 Mhz ELT's are not mandatory yet, for example. Also, since you'll be using the Exception to Chapter 549 to import, note that you don't need the massive "this aircraft is operating without a C-of-A..." label. The text size is not specified, and the text is simpler, for those using the exception.
Happy to answer questions about importing, my -6 started out in the US as well.
