I didn't take notes on our Seattle trip so these random thoughts just keep popping up. Outsider told me this one and I was a bit skeptical.

There are some hoops to jump through for the 5 year limitation, but otherwise it is ten years. http://www.tripadvisor.com/Travel-g153339-c49436/Canadawi.Or.Dui.Driving.Convictions.html Doesn't apply to me, but just found it interesting.
