Identity

Southern Ontario can be distinguished from Northern Ontario because it is far more densely populated and contains most of the province's cities, major roads, and institutions. Northern Ontario, in contrast, contains more natural resources and remote wilderness. Although it has no saltwater coastline, the region has an abundance of freshwater coastlines on three

History

The French explored and colonized Territorial Southern Ontario in the 17th century and forged relations with the Wyandot ''Huron'' people, based around the Georgian Bay/Lake Simcoe area. Other Iroquoian speaking people to the south were the Petun and Neutral Nation, and further northeast, Algonquins inhabited the upper Ottawa River/Madawaska Valley areas and the Mississaugas moved south from northern Lake Huron, settling lands in both the Kawartha region and just west of Toronto.

Demographics

Southern Ontario is home to over 94%, or 12.1 million, of Ontario's total population of 12.9 million (and about 35% of Canada's total population), compared to approximately 750,000 in Northern Ontario. This is due to many factors, including the more arable land in the south, its more moderate climate, well-used transportation (water, land, and air) routes, as well as a long history of early European

Climate

Southern Ontario has a

with four distinct seasons. The average highs in July for the region range between . The average high in January ranges from . The highest recorded temperature in Southern Ontario was with the humidex. During cold snaps, winter temperatures can occasionally drop below . The climate found over most of southern Ontario falls within the ''Dfb'' and '' Dfa'' climate subtypes, much warmer or milder than the northern part of the province due to lower latitude, presence of bodies of water, and intense urbanization. Harsh weather is not uncommon in the region. In the summer months, Southern Ontario is susceptible to tornadoes but far more often, straight line wind damage, hail and localized flooding from severe thunderstorms. Although the majority of tornadoes rarely cause excessive damage, the region is on the periphery of

s. Small earthquakes occur in the region. The 5.8 Cornwall–Massena earthquake occurred in 1944 and had a maximum Mercalli intensity of VII (''Very strong''). Many tourists visit the area in the autumn months to look at the bright, vibrant colours of fall foliage. Southern Ontario has a very different climate from the rest of the country. It is the only area of Canada that has Carolinian forest. Many trees, plants, and wildlife in Southern Ontario are not found anywhere else in Canada. Some rare trees in this region include the tulip tree, pawpaw fruit tree, and the cucumber tree. The Carolinian forests of Southern Ontario have in large part been destroyed by development sprawl. Very few original growth areas remain. The region has the most freshwater beaches in the nation. With relatively warm waters by mid-summer due to the hot and humid summer months with significant coastlines of white sand, the major beaches in the region are visited by millions of tourists every summer. The most popular beaches are Wasaga Beach, Grand Bend, Sauble Beach, and Sandbanks.
