Ontario, Canada Weather and Climate

Geographical location

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

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

There are a number of bodies of water between Ontario and the United States, including rivers and lakes. The region is divided into three different types of landscape: Half of the province is covered by the so-called Canadian shield, a rather barren but mineral-rich region. The second zone is the lowlands 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, in which about 75 percent of the population of Ontario live. Ontario has five national parks and shares the popular Niagara Falls with the state of New York on the state border. Niagara Falls is the name of the sister cities on either side of the falls.

Toronto is about 6350 kilometers away from Frankfurt, the flight time is around 8.5 hours.

When to go to Ontario

Depending on your personal preferences, there are various recommendations for the best time to travel to the province of Ontario. Vacationers who like the Indian summer with colorful vegetation and mild temperatures should arrive in late autumn. The winter time is less recommended, especially 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, in which cold sea air meets the stored warmth of the lakes unabated. In the north of the province there is usually constant ground frost and snow from November to April.

The main season in Ontario and the capital Toronto is between June and September in the warm and usually rather humid summer. The time from April to October is suitable for a visit to Niagara Falls, although the world-famous attraction is regularly extremely crowded and overcrowded in midsummer. The marginal months in early summer and the transition period to autumn can therefore be a good alternative.
