Apparently Ontario and presumably a Canadian driver license isn't valid in the state of Georgia. Is this how America operates now, shaking down tourists and visitors because no one wants to pay taxes down there?
A lot of people I work with now talk about avoiding travel in the states - too unstable.
"Georgia recognizes unexpired driver’s licenses issued to and held by residents of other countries as long as the foreign license is unexpired. Generally, you may drive in Georgia for up to one year on an unexpired foreign license. Please note that in the case of a driver's license issued by the driver's licensing authority of a foreign country, a law officer may consult such person's passport or visa to verify the validity of such license, if available."
