Ontario is one of the ten provinces of Canada, located in east-central Canada. It is Canada's most populous province by a large margin, accounting for nearly 40 percent of all Canadians, and is the second largest province in total area. Ontario is fourth largest in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto.

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 northeast, and to the south by the US states of (from west to east) Minnesota, Michigan, Ohio, Pennsylvania and New York. Almost all of Ontario's 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. There is only about of land border made up of portages including Height of Land Portage on the Minnesota border.

Ontario is sometimes conceptually divided into two regions, Northern Ontario and Southern Ontario. The great majority of Ontario's population and arable land is located in the south. In contrast, the larger, northern part of Ontario is sparsely populated with cold winters and is heavily forested.

Ontario is the most populous province in Canada.

This article contains all the viruses of Ontario family.

Ontario.512 is a computer virus, discovered in July 1990. It is named after its point of isolation, the Canadian province of Ontario. This family of Computer virus consists of Ontario.1024,Ontario.512 and Ontario.2048. Because Ontario.1024 was also discovered in Ontario, it is likely that both viruses originate from within the province. By the Ontario.2048 variant, the author had adopted "Ontario" as the family's name and even included the name "Ontario-3" in the virus code.

Ontario was a federal electoral district represented in the Canadian House of Commons from 1925 to 1997. It was located in the province of Ontario. This riding was created in 1924 from Ontario South riding.

It initially consisted of the townships of Pickering, Whitby (East and West), Reach, and Scugog, and the city of Oshawa in the county of Ontario. In 1947, the townships Scott and Uxbridge were added to the riding.

In 1966, it was redefined to consist of, in the County of Ontario, the Townships of Pickering, Reach, Scott, Scugog, Uxbridge, East Whitby and Whitby (excluding the area between the west limit of the City of Oshawa and the east limit of the Town of Whitby lying south of the road allowance between Concessions 2 and 3), and, in the County of York, the Townships of Georgina and North Gwillimbury, and all the islands of Georgina Island Indian Reserve No. 33.

In 1976, it was redefined to consist of the Township of Uxbridge, and the Towns of Ajax, Pickering and Whitby. In 1987, the Township of Uxbridge was excluded from the riding, along with the part of the Town of Whitby north of Taunton Road East and Taunton Road West (Durham Regional Road No. 4).

The electoral district was abolished in 1996 when it was redistributed between Pickering—Ajax—Uxbridge and Whitby—Ajax ridings.

Ontario was a provincial riding in the Canadian province of Ontario. Called Ontario South until 1933, it was active from 1867 to 1975. For its entire existence, the riding contained parts of or all of Ontario County, a now-defunct county which comprised most, but not all, of the contemporary Regional Municipality of Durham, including the municipalities of Ajax, Oshawa, Pickering and Whitby. After 1955, however, a separate riding called Oshawa was created to serve the city of Oshawa, Ajax and parts of Pickering and Whitby, while the Ontario riding continued to serve the more rural areas in the county. In 1966 a new Ontario South was created to represent Ajax, Pickering and Whitby. The remainder of the riding was divided into the new ridings of Durham West, Durham East and Durham—York in 1975.
