I did the same as the other Canadians have posted. The replacement from MC was a plate that needs to be riveted on, not an adhesive sticker like the original.
Customs official didn't even come out to check the boat HIN or the trailer VIN when I came across!! Also never even looked at the $2000 worth of stuff (which I had declared) that was stored in the boat -- spare tire, new prop, ski equip, etc. etc.
