From St. John's to Victoria, Canadians love to brag about the weather that they endure (or enjoy!). Surely their community must get the most in the entire country! But which Canadian city really is the rainiest, the snowiest or the windiest? And where is the sunshine capital?

To find the answers, David Phillips, Environment Canada's Senior Climatologist, and the nation's favourite weather guru, has analyzed 30 years of recent weather data for Canada's 100 largest cities. His results will not only provide for entertaining conversations around the dinner table, but will also be of assistance to local governments, Chambers of Commerce, tourism and recreation businesses and those seeking weather havens for retirement or health purposes.
