It had me going for a while!
I do remember a few years ago, someone asking on this very forum, about their first planned trip to Canada.
They were going to take the 401 Highway through Toronto. They asked if it was a good road or was it "a narrow track that wound its way through the wilderness" !!
It is the busiest road not only in North America, but also in the world!
I have also heard of people looking at the speed limit signs on Google Streetview and wondering why they were so high!
I finally caught on when they mentioned driving on the left.
However , I do remember arguing with a phone manufacturer that I had not voided the warranty on my phone by plugging it in to a different power source. She said that Canadian power was different as it was part of France!
