The first time I updated my DL at YUL, I handed it over to the Canadian agent working the reception desk.

She disappeared, and an American agent came out yelling at me about an expired driver's licence. The same one that had been updated 2 years prior.

It's amazing that these people work in the same office yet can't seem to be in sync...
