Canadian Cities are Weather Winners
David Phillips, Environment Canada's Senior Climatologist, and the nation's favourite weather guru, has analyzed 30 years of weather data for Canada's 100 largest cities to provide the ranking of Canadian cities based on various weather categories (such as the hottest summer, the coldest summer, most freezing rain days).

Province-Territory Weather Winners
Province-Territory Weather Winners looks at how each Canadian province and territory ranks in 70 different weather categories (such as the coldest/warmest province or territory year-around, the province or territory with the most heavy snow days). Data for 30 years from 150 weather stations, representative of the geography in each province and territory, were used to compute averages for each jurisdiction.
