Welcome to Ontario, the most multicultural province in Canada, where half of all new immigrants make their home. Ontario is a land of opportunity. It is a prosperous, democratic society built by the hard work of generations of immigrants.
On the map, Ontario is in the middle of Canada. It is also the hub of the Canadian economy. It is a magnet for manufacturing, finance, tourism and other industries. It’s also a leader in science and the arts. Our population of 12 million includes people from 200 countries who speak as many as 130 languages. Our cities are vibrant and our scenery spectacular.
Ontario is bordered by the province of Manitoba to the west, Hudson Bay and James Bay to the north, and Quebec to the east, and to the south by the U.S. states of Minnesota, Michigan, New York, Ohio and Pennsylvania. All but a small part of Ontario's 2,700 km (1,678 mi) border with the United States follows inland waterways: from the west at Lake of the Woods, eastward along the major rivers and lakes of the Great Lakes/Saint Lawrence River drainage system. These are the Rainy River, the Pigeon River, Lake Superior, the St. Marys River, Lake Huron, the St. Clair River, Lake St. Clair, the Detroit River, Lake Erie, the Niagara River, Lake Ontario and along the St. Lawrence River from Kingston, Ontario, to the Quebec boundary just east of Cornwall, Ontario.
Ontario contains about 250,000 freshwater lakes.
The climate of Ontario varies largely from season to season and from one location to another. It is affected by 3 air sources: cold, dry and arctic air from the north (dominant factor during the winter months, and for a longer part of the year in far northern Ontario); Pacific polar air crossing in from the western Canadian Prairies/US Northern Plains and warm, moist air from the Gulf of Mexico and the Atlantic Ocean. The effects of these major air masses on temperature and precipitation depend mainly on latitude, proximity to major bodies of water and to a small extent, terrain relief. In general, most of Ontario's climate is classified as humid continental. Ontario has three main climatic regions.
