Kitchener, Ontario in the context of "Guelph"

Windsor (/ˈwɪndzər/ WIND-zer) is a city in southwestern Ontario, Canada. It is situated on the south bank of the Detroit River directly across from the U.S city of Detroit, Michigan. Geographically located within but administratively independent of Essex County, it is the southernmost city in Canada and marks the southwestern end of the Quebec City–Windsor Corridor. The city's population was 229,660 at the 2021 census, making it the third-most populated city in Southwestern Ontario, after London and Kitchener. This represents a 5.7 percent increase from Windsor's 2016 population census of 217,188.

The Detroit–Windsor urban area is North America's most populous trans-border conurbation. Linking the Great Lakes Megalopolis, the Ambassador Bridge border crossing is the busiest commercial crossing on the Canada–United States border, carrying about one-quarter of the two countries' trade volume.

Waterloo is a city in the Canadian province of Ontario. It is one of three cities in the Regional Municipality of Waterloo (formerly Waterloo County). Waterloo is situated about 94 km (58 mi) west-southwest of Toronto, but it is not considered to be part of the Greater Toronto Area (GTA). Due to the close proximity of the city of Kitchener to Waterloo, the two together are often referred to as "Kitchener–Waterloo", "K-W", or "The Twin Cities". Nearby Cambridge, Ontario is also sometimes grouped in, creating KWC or "Tri-cities".

While several unsuccessful attempts to combine the municipalities of Kitchener and Waterloo have been made, following the 1973 establishment of the Region of Waterloo, less motivation to do so existed, and as a result, Waterloo remains an independent city. At the time of the 2021 census, the population of Waterloo was 121,436.

GO Transit is a regional public transit system serving the Greater Toronto Area and the Greater Golden Horseshoe region of Ontario, Canada. With its hub at Union Station in Toronto, GO Transit's green-and-white trains and buses serve a population of more than seven million across an area over 11,000 square kilometres (4,200 sq mi), stretching from Kitchener in the west to Peterborough in the east, and from Barrie in the north to Niagara Falls in the south. In 2024, the system had a ridership of 71,827,500. GO Transit operates diesel-powered double-decker trains and coach buses, on routes that connect with all local and some long-distance inter-city transit services in its service area.

GO Transit began regular passenger service on May 23, 1967, as a part of the Ontario Ministry of Transportation. Since then, it has grown from a single train line to seven lines. GO Transit has been constituted in a variety of public-sector configurations. Today, it is an operating division of Metrolinx, a provincial Crown agency with overall responsibility for integrative transportation planning within the Greater Toronto and Hamilton Area and is projected to grow dramatically with electrification, increased frequency and new stations through the GO Expansion, which is scheduled to be completed in phases through 2025–2032.

The Grand River, formerly known as the River Ouse, is a large river in Ontario, Canada. It lies along the western fringe of the Greater Golden Horseshoe region of Ontario which overlaps the eastern portion of southwestern Ontario, sometimes referred to as Midwestern Ontario, along the length of this river. From its source near Wareham, Ontario, it flows south through Grand Valley, Fergus, Elora, Waterloo, Kitchener, Cambridge, Paris, Brantford, Ohsweken, Six Nations of the Grand River, Caledonia, and Cayuga before emptying into the north shore of Lake Erie south of Dunnville at Port Maitland. One of the scenic and spectacular features of the river is the falls and Gorge at Elora.

The Grand River is the largest river that is entirely within southern Ontario's boundaries. The river owes its size to the unusual fact that its source is relatively close to the Georgian Bay of Lake Huron, yet it flows southwards to Lake Erie, rather than westward to the closer Lake Huron or northward to Georgian Bay (most southern Ontario rivers flow into the nearest Great Lake, which is why most of them are small), thus giving it more distance to take in more water from tributaries.
