The climate of Ontario (Canada)
Ontario is the most densely populated province in Canada and is situated on Lake Ontario. Two large cities can be found in Ontario: Ottawa and Toronto. Most tourists come here to see the Niagara Falls; a must-see when you visit Canada. The climate in Ontario depends on the season and the place you are in. North-Ontario mainly has a continental climate with cold winters and mild summers. Most of the precipitation falls in the form of warm showers and thunderstorms. During the winter heavy snowstorms are not uncommon. Precipitation figures are high because of the influence of the large lakes that are in the vicinity. During the spring and summer tropical temperatures are moderated by the water. Extreme weather conditions are not uncommon in Ontario. In the southern part of Ontario tornadoes are not uncommon and thunderstorms frequently occur during the summer.

More climate information
Climate figures are very useful but donít present a general impression of the climate and the eventual weather circumstances within a certain period. The figures donít always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
