Hi oldreddog,
I seen that you were bringing a us car back into car. I brought one back in 2012. Please know that you can avoid dealing with Porsche Canada to get a recall letter/inspection. If you stop by a Porsche dealership on your way back to the border, ask for a screen print of the service computer screen showing that there are no open jobs on your car - this is the same thing, and free. I also picked up air bag stickers from Chevy to pass the RIV inspection. I can give you all the details I did if you like, I only spent $15 to get my car into Canada + riv inspection fees.
