Don't listen to everyone else here... I am a Police Officer in BC, and I'm assuming that you got the ticket in BC as you live in Washington. We do not issue warrants for unpaid tickets in BC. However, the unpaid ticket could go to collections. You could also become a prohibited driver in BC. That means that if you're caught driving, even with a valid Washington State DL, your car could be impounded, and you will get even more fines. My suggestion is to pay the ticket, and to save yourself the hassle in the future.
