Canada Climate and Weathers : Usually milder temperatures year round than the interior areas of Canada, coastal areas can have very high rainfall. Areas such as coastal British Columbia get some of 
the highest rainfall in Canada, but it can be very dry in the southern BC Interior due to the Coast Mountains acting as a rain shadow. The wind can be a big factor in the Canadian Prairies because there are wide open areas not unlike those in the Midwest states of the US, and makes for unpleasant windchills during cold weather in the winter. The average temperature is typically colder in Canada than in the US and Western Europe as a whole, don't forget bring your jacket if visiting between October and May, and early and later than this if visiting areas further north. The rest of the year, in most of the country, daytime highs are generally above 15 degrees Celsius.
Trying to distill the climate of Canada into an easy to understand statement is impossible, given the vast area that this country occupies. The southernmost point of mainland southern Ontario, Point Pelee, and the nearby islands in Lake Erie at a very similar latitude to northern California, and has a climate similar to the eastern US. Iqaluit, the capital of Nunavut, is just south of the Arctic Circle and remains very cold for most of the year.
However, as most of the Canadian population resides within a couple of hours drive of the southern border shared with the United States, a visitor to these areas will probably not have to endure the weather that accompanies a trip to the northern territories. In fact, summers can be hot in parts of Canada. Summer temperatures over 38°C are not unusual in extreme Southern Ontario and the southern Interior of British Columbia. Toronto's climate is only slightly cooler than many cities in Northeastern United States, and summers in the southern parts of Ontario and Quebec are often hot and humid. In the BC Interior, Alberta and Saskatchewan, the humidity is often low during the summer, even during hot weather.
Climate in Canada also depends in large part on how close to the coast you travel. Many inland cities, especially those in the Prairies, experience extreme changes in weather. Winnipeg, Manitoba has hot summers, where it can easily exceed 35 degrees Celsius, yet experiences very cold winters where -40 degrees Celsius is not uncommon. The hottest temperatures in Canadian recorded history have been in southern Saskatchewan - as hot as 45 degrees Celsius. Conversely, coastal cities in British Columbia and the Atlantic Provinces are generally milder year-round and do not usually get very much snow, although the Atlantic Provinces can get hit by serious blizzards and lengthy cold snaps in winter. The coastal areas of British Columbia have the mildest climate anywhere in Canada. It is mild enough for even some species of palms to grow in Vancouver and Victoria. Both of these West Coast cities are temperate and get very little snow, and seldom experience temperatures below 0 or above 27 degrees Celsius.
