Ontario is the largest province of Canada by population, and second largest by area. It is located in the center of the country, between Quebec and Manitoba. Four of the Great Lakes are on its southern border, separating the province from the states of New York, Michigan and Minnesota. Ontario is the center of Canada's manufacturing economy, and its capital, Toronto is the country's largest city. The federal capital of Ottawa is also located in Ontario.

It is not to be confused with Ontario, CA, a place where several major leaguers have been born.
