It's no secret that Canada has some pretty bad traffic, but it's officially been confirmed — Canadian cities have some of the most congested roads in North America.

According to a traffic index by TomTom, a global navigation company, four Canadian cities are among the worst offenders for traffic congestion.

At number three, Vancouver claims the title of the most congested city in Canada — a fact that surprised none of the locals.

Vancouver though! I wouldn't be surprised if hell was just sitting in their rush hour traffic forever.

The city has a congestion level of 39%.

Toronto claims spot number six, with a 33% congestion level — a ranking that most locals could have guessed.
