Bruce Peninsula in the context of Great Lakes–St. Lawrence Lowlands

The Georgian Bay (French: Baie Georgienne) is a large bay of Lake Huron, in the Laurentia bioregion. It is located entirely within the borders of Ontario, Canada. The main body of the bay lies east of the Bruce Peninsula and Manitoulin Island. To its northwest is the North Channel.

The Georgian Bay is surrounded by (listed clockwise) the districts of Manitoulin, Sudbury, Parry Sound and Muskoka, as well as the more populous counties of Simcoe, Grey and Bruce. The Main Channel separates the Bruce Peninsula from Manitoulin Island and connects the Georgian Bay to the rest of Lake Huron. The North Channel, located between Manitoulin Island and the Sudbury District, west of Killarney, was once a popular route for steamships and is now used by a variety of pleasure craft to travel to and from the Georgian Bay.

The Ontario Peninsula is the southernmost part of the province of Ontario and of Canada as a whole. It is bounded by Lake Huron on the west, Lake Ontario on the east, and Lake Erie on the south. At its tip, it is separated from Michigan by the Detroit and St. Clair rivers, as well as Lake St. Clair. The peninsula also includes the Bruce and Niagara peninsulas, one projecting into Lake Huron and the other projecting towards New York, from which it is separated by the Niagara River.

The corner of the peninsula that lies on Lake Ontario is known as the Golden Horseshoe and forms Canada's largest population centre. Other large cities include London and Windsor.

The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by three of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland, Central Lowland and East Lowland. The West Lowland includes the Niagara Escarpment, extending from the Niagara River to the Bruce Peninsula and Manitoulin Island. The Central Lowland stretches between the Ottawa River and the St. Lawrence River. The East Lowland includes Anticosti Island, Îles de Mingan, and extends to the Strait of Belle Isle.

The St. Lawrence Lowlands is one of the most densely populated, prosperous and productive regions in Canada. Major urban areas include Toronto, Montreal, Ottawa-Gatineau and Quebec City.

King's Highway 6, commonly referred to as Highway 6, is a provincially maintained highway in the Canadian province of Ontario. It crosses a distance of 480 km (300 mi) between Port Dover, on the northern shore of Lake Erie, and Espanola, on the northern shore of Lake Huron, before ending at the Trans-Canada Highway (Highway 17) in McKerrow.

Highway 6 was one of several routes established when Ontario first introduced a highway network on February 26, 1920, following several pioneer wagon trails. The original designation, not numbered until 1925, connected Port Dover with Owen Sound via Hamilton and Guelph. When the Department of Highways (DHO) took over the Department of Northern Development (DND) in 1937, Highway 6 was extended north through the Bruce Peninsula to Tobermory. In 1980, the entire length of Highway 68 on Manitoulin Island and north to Highway 17 became a northern extension of Highway 6. Small modifications were made to the route of Highway 6 in 1997, but it was largely untouched by provincial downloading.

Bruce County is a county in Southwestern Ontario, Canada. It has eight lower-tier municipalities with a total 2021 population of 73,396. It is named for James Bruce, 8th Earl of Elgin and 12th Earl of Kincardine, the sixth Governor General of the Province of Canada. The Bruce name is also linked to the Bruce Trail and the Bruce Peninsula.

The county has three distinct areas. The Bruce Peninsula is part of the Niagara Escarpment and is known for its views, rock formations, cliffs, and hiking trails. The Lakeshore includes nearly 100 km of fresh water and soft sandy beaches. Finally, the Interior Region has a strong history in farming.

The Niagara Escarpment Biosphere Reserve (French: Réserve de biosphère de l'Escarpement du Niagara) (established 1990) is a UNESCO Biosphere Reserve located in Ontario, Canada. The reserve stretches 725 kilometres (450 mi) along the Niagara Escarpment from Lake Ontario (near Niagara Falls) to the tip of the Bruce Peninsula (between Georgian Bay and Lake Huron). The Escarpment corridor crosses two major biomes: needle leaf forests in the north and temperate broadleaf forest in the south.
