Hottest Canadian Cities

You could say Victoria, British Columbia is the major city in Canada with the hottest weather. It has highest average daily maximum and minimum temperatures among the country's large cities.

But if you look at the rankings for frost-free period, Vancouver, BC is typically free of frost for 26 days longer than Victoria.

As for really hot weather, neither BC city even makes it into the top ten. A day with temperatures of 30 degrees Celsius (86 ° Fahrenheit) or above are far less likely to happen in Vancouver or Victoria than most other major Canadian cities.

Perhaps the title of hottest city in Canada should go to Windsor, Ontario. Windsor makes it into the top ten lists for all criteria. The only other city to do so is St. Catharines, Ontario, but it sits behind Windsor in every category. In fact for each measure, Windsor ranks among the top five of the hottest Canadian cities.
