Vancouver, Toronto, Halifax Lead Canadian Cities in 2025 TomTom Traffic Index
Traffic congestion and travel times have worsened globally in 2025 according to the latest annual Traffic Index from GPS manufacturer TomTom, now in its 15th edition. In fact, among the nearly 500 major cities that are part of the study, only 34 saw an improvement compared to 2024 in terms of time lost by motorists in traffic.
The Traffic Index is based on data extracted from more than 600 million in-car navigation systems and smartphones.

It’s interesting to note that the level of congestion has decreased in 125 cities worldwide, but it is mainly public transport networks and cyclists that have benefited, not so much drivers, says TomTom.
Mexico City, Mexico (pictured below), was the most congested city in the world in 2025, followed by Bengaluru, India, and Dublin, Ireland. That being said, Barranquilla, Colombia, had the slowest traffic: it took drivers an average of 3 minutes and 40 seconds to travel 1 km.
Los Angeles’ congestion level was the worst in the U.S. last year, unsurprisingly, yet the traffic still moved fairly quickly. In terms of travel time, it ranked 385th in the world.
Meanwhile in Canada…
Toronto, which ranked third among the world's most congested cities in 2023, has fallen to 113th place in TomTom's latest Traffic Index. Vancouver is currently the worst Canadian city, ranking 45th globally, while Halifax rounds out the top three (147th).
Next come Montreal (205th), Quebec City (208th) and Winnipeg (213th).
A separate study released by INRIX last December told a different story, mind you. Montreal appeared at the top of the list of the most congested cities in Canada and 28th in the world ranking, which was dominated by Istanbul, Mexico City and Chicago.
