If I had $20,000 in fines owing on my licence because I'm an idiot and just racked up fines, then move to the states, abandon my Ontario licence, would this have any implications on getting a Texas licence? If it doesn't, what incentive is there for an Ontario driver to pay the fine if they will eventually leave?
A friend of mine left the country with less than a couple thousand in outstanding fines and came back 10 years later to visit he was curious as to what became of the fines and the status of his licence (should he ever want to move back). When he inquired at the courthouse the fines were still there waiting for him and his licence was suspended (but not renewable if he paid the fines). He didn't pay them and went back to the country he moved to and lives his life. So you can really never come back and expect to find a clean slate.
There are reciprocal agreements in place amongst several states (including Texas) where Ontario can request your out of province licence be suspended for non-payment of fines, but to the best of my understanding that only happens when youÃƒÂ¢Ã‚â‚¬Ã‚â„¢re charged while driving with an out of province licence (i.e. Texas resident charged with speeding while visiting Ontario). If you obtain your out of province licence after the fact, Ontario would not be aware and the other jurisdiction never notified.
And just be aware if youÃƒÂ¢Ã‚â‚¬Ã‚â„¢re planning on taking a vehicle with you to Texas, donÃƒÂ¢Ã‚â‚¬Ã‚â„¢t make the mistake of driving there while suspended. Border guards and any U.S. police service that queries your Ontario licence will see your suspension.
No state or province will allow you to hold 2 separate drivers license.
There's a reciprocal agreement that will allow you to exchange your license for another state or province. In most cases, it will allow you to exchange your license without going through classes or mandatory wait times. They will NOT do exchanges with a license that is not valid due to suspensions. Once you exchange, you'll give up your previous license.
I don't know if there's anything that would stop you from applying for a state license from scratch. You can't do it state from state, but province to state, I don't believe there's anything stopping you.
As already pointed out, if you return to Ontario, your new license is useless. You'll be considered driving under suspension and they'll confiscate your current license.
