I am moving my car to Utah from Virginia. How quickly do I have to register my car in Utah and change the plates? Do I have to insure my car in Utah or can I maintain my Virginia insurance?

I am a licensed US driver, but will be moving to Canada next week for an assignment that is expected to last 2 to 4 years. Do I need to get a Canadian Driving License, and what is the process? Also, I'll be buying a vehicle there. Where can I get insurance quotes?
