U.S. driver's licenses are valid in Canada. It is so easy to drive in Canada, similar to driving in the U.S. with a few differences: Distances and speeds are posted in metric units (kilometers), the maximum speed limit in Canada is 50km per hour in cities, 80km per hour on highways, and 100 km/ per hour on rural highways. There are no toll booths in Canada, however there is one I saw in town of Jasper. I believe they ask for the park fees. I think. Not sure though.
There are certain highways especially in the small towns in Alberta have cameras that take a photo of your license plate if you drive over the maximum speed. Other than that, driving in Canada is smooth as the wind.
The scenery of the mountain and the prairie is pretty awesome!
