Canadian A&W is really good, and tbh it's kinda surprising that Canadian A&W hasn't bought out American A&W and tried to expand there.
That being said, I believe Canadian A&W is much more heavily tilted toward the western part of the country, so maybe they feel they have their hands full trying to grab marketshare in Ontario, Quebec and further.
My wife and I stopped in an A&W in Toronto a few years back—we were walking, and hungry, and just needed food. My expectations were not high at all, but damn—it was good!
