UPDATE Theft insurance info--first hand attn Canadians!

From my experience I found that they didn't want the title of the vehicle that I showed crossing the border and registered with. What they wanted was the bill of sale for the vehicle. I had mine at home in the filing cabinet. I had a certified copy made then forwarded it to Mexico. Of course its a bit different as my vehicle was recovered and I was dealing with the gov't not the insurance comp.
