Windsor ( ) 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 major 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.
Windsor is a major contributor to Canada's automotive industry and is culturally diverse. Known as the "Automotive Capital of Canada", Windsor's industrial and manufacturing heritage is responsible for how the city has developed through the years.
History
Early settlement
At the time when the first Europeans arrived in the 17th century, the Detroit River region was inhabited by the Huron, Odawa, Potawatomi and Iroquois First Nations. The land along the Detroit River was part of the Three Fires Confederacy between the Ojibwe, Potawatomi, and Odawa and was referred to as Wawiiatanong or Wawiiatanong Ziibi meaning "where the river bends" in Anishinaabemowin.
Later settlement
A French agricultural settlement was established at the site of Windsor in 1749. It is the oldest continually inhabited European-founded settlement in Canada west of Montreal. The area was first named la Petite Côte ("Little Coast"—as opposed to the longer coastline on the Detroit side of the river). Later it was called La Côte de Misère ("Poverty Coast") because of the sandy soils near LaSalle.
Windsor's French-Canadian heritage is reflected in French street names such as Ouellette, Drouillard, Pelissier, François, Pierre, Langlois, Marentette, and Lauzon. The current street system (a grid with elongated blocks) reflects the Canadien method of agricultural land division, where the farms were long and narrow, fronting along the river. Today, the name of the north–south street often shows the name of the family that farmed the land where the street is today. The street system of outlying areas is consistent with the British system for granting land concessions. There is a sizeable French-speaking minority in Windsor and the surrounding area, particularly in the Lakeshore, Tecumseh and LaSalle areas.

In 1797, after the American Revolution, the settlement of "Sandwich" was established. It was later renamed Windsor, after the town in Berkshire, England. The Sandwich neighbourhood on Windsor's west side is home to some of the city's oldest buildings, including Mackenzie Hall, originally built as the Essex County Courthouse in 1855. Today, this building is a community centre. The city's oldest building is the Duff-Baby House, built in 1792. It is owned by Ontario Heritage Trust and houses government offices.

The François Baby House in downtown Windsor was built in 1812 and houses Windsor's Community Museum dedicated to local history.
Windsor was the site of a battle during the 1838 Upper Canada Rebellion. It was attacked by a band of 400 Americans and rebels from Detroit who burned a steamboat and two or three houses before being routed by the local militia. Later that year, Windsor also served as a theatre for the Patriot War.

In 1846, Windsor had a population of about 300. Two steamboats offered service to Detroit. The barracks were still in operation. There were various tradespeople and other occupations, including bank agencies and post offices. There were estimated to be 20,000 to 30,000 African-American refugees who settled in Canada, with many settling in Essex County, Ontario.
The Windsor Star Centennial Edition in 1992 covered the city's past, its success as a railway centre, and its contributions to World War I and World War II fighting efforts. It also recalled the naming controversy in 1892 when Windsor aimed to become a city. The most popular names listed in the naming controversy were South Detroit, The Ferry (from the ferries that linked Windsor to Detroit), Windsor, and Richmond (the runner-up in popularity). Windsor was chosen to promote the heritage of new English settlers in the city and to recognize Windsor Castle in Berkshire, England. However, Richmond was a popular name used until World War II, mainly by the local post office.
20th century
Sandwich, Ford City and Walkerville were separate legal entities (towns) until 1935. They are now historic neighbourhoods of Windsor. Ford City was incorporated as a village in 1912; it became a town in 1915 and a city in 1929. Walkerville was incorporated as a town in 1890. Sandwich was established in 1817 as a town with no municipal status. It was incorporated as a town in 1858 (the same year as neighbouring Windsor).
Windsor annexed these three towns in 1935. The nearby villages of Ojibway and Riverside were incorporated in 1913 and 1921, respectively. Both were annexed by Windsor in 1966. During the 1920s, alcohol prohibition was enforced in Michigan while alcohol was legal in Ontario. Rum-running in Windsor was a common practice then.
On October 25, 1960, a massive gas explosion destroyed the building housing the Metropolitan Store on Ouellette Avenue. Ten people were killed, and at least one hundred were injured. The Windsor Star commemorated the 45th anniversary of the event on October 25, 2005.
