Geographical location

Ontario is a province in southeastern Canada and is home to around 13 million inhabitants. With Canada’s largest city (Toronto) and the country’s capital (Ottawa), Ontario is one of the country’s most important regions both politically and economically.

The province borders Québec to the east and Manitoba to the west and five US states to the south: Minnesota, Ohio, Pennsylvania, Michigan and New York.

Between Ontario and the United States there are several waters, including rivers and lakes. The region is divided into three different types of landscape: Half of the province is occupied by the so-called Canadian Shield, a rather barren but mineral-rich region. Second zone is the lowland of Hudson Bay in the northeast with numerous swamps and forests.

The third zone and main region of Ontario is the fertile valley in the south, which is home to about 75 percent of Ontario’s population. Ontario has five national parks and shares the popular Niagara Falls on the state border with the state of New York. Niagara Falls is the name of the sister towns on both sides of the waterfalls.

Southern and southeastern Ontario has a temperate climate with humid summers and cold winters. In the east and in the centre of the province the climate is more continental than in the south, the summers here are quite short and warm, the winters rather long and cold.

Winters are longest and coldest in northern Ontario, and summer time is comparatively short. The climate is described here as subpolar. Compared to the south, there is less precipitation in the north. However, there is usually snow from October to May.

In general, there is regular rainfall throughout the year in Ontario, but most rain falls in summer. In the provincial capital Toronto and the Niagara Falls about 80 miles away, it is pleasantly warm from June to mid-September with daytime temperatures of 25 °C to 27 °C.

When to go to Ontario?

Depending on your personal preferences, there are various recommendations for the best travel time for the province of Ontario. Holidaymakers who like the Indian Summer with its colourful vegetation and mild temperatures should arrive in late autumn. Wintertime is less recommended for city trips because of the sometimes enormous cold and heavy rainfall.

A phenomenon in winter is the so-called Lake Effect with its enormous thunderstorms and large snowfalls, during which cold sea air meets the stored warmth of the lakes undiminished. In the north of the province there is usually even ground frost and snow from November to April.

The high season in Ontario and the capital Toronto is between June and September in warm and rather humid summers. Niagara Falls can be visited from April to October, when the world-famous attraction is regularly extremely crowded and overcrowded in high summer. The fringe months in early summer and the transition to autumn can therefore be a good alternative.

    Nina, 34 years old was there in February

    The travel season in February is very suitable for a city tour. For example, Toronto is very well connected to public transport and the Path, so the ice-cold weather is no problem. – 5 ° C in humid-cold Germany I feel more unpleasant than the dry cold with – 15 ° C in Toronto.
