The largest province in Canada by population and the the second largest by size. Located west of Quebec, east of Manitoba, and north of New York State, Michigan, and Minnesota. Ontario is the economic engine of Canada and home to Canada's largest city, Toronto. Other large cities include Ottawa (the national capital), Hamilton, London, Kitchener-Waterloo, and Windsor.

Ontario is economically and ideologically split between the populated, urban, and wealthy south and the vast reaches of the northen part of the province.

Most people from other parts of Canada think Ontarians are arrogant wankers that would sell their own mother for a quick buck or a blow job. However, most of these criticisms come from people with small penises and no balls.
Ontario is the most important province in Canada.

I love Ontarians, they support the rest of Canada.

I hate people from Ontario because I'm a right-wing, red-neck freak from Alberta.

Actually, in Canada you can drive at 16 and drink at 19! Ontario is Canada's largest province by population, 12 million+. I also is home to the nation's largest city, Toronto, with a population of roughly 3 million. Toronto is also home to the world's tallest structure, the CN Tower at about 1 800 feet.

Ontario is highly sterotyped by the rest of Canada. But what they don't relise if it wasn't for us, there wouldn't be a Canada.

Ontario is also called an election backbone becuase it accounts for more than 30% of the votes in an Canadian Election.

most populous province in canada, although most people live in the very southern part of the region, along the 401 corridor. ontario is very much like new york state. a mass of people live in the south, and ridicule the northern part. contains the megaplex they call toronto and the surronding GTA (greater toronto area, not the video game), with its mass of over 6 million people. also has the nat'l capital of ottawa, home to the most annoying of all hockey teams and a fan base that is unable to support CFL football. windsor and oshawa are now north america's auto capitals, since detroit went down the crapper. hamilton is the steel center and is suburbs basically now connect with the western suburbs of toronto. london is another big city too, but no one really cares about it. the rest of canada thinks the media in the country is biased toward ontario, and they're prob right. the only canadian province americans really know exists, and the place where 19-20 yr old usa kids jump the border to go to niagara falls bars.
more than 25% of canada's population lives in ontario's golden horeshoe. more than 25% of american college students pass out in niagara falls ontario hotel rooms after guzzling too much liqour they bought at bars or the LC.
