Mississauga is a Canadian city in the province of Ontario. Situated on the western shore of Lake Ontario in the Regional Municipality of Peel, it borders Toronto (Etobicoke) to the east, Brampton to the north, Milton to the northwest, and Oakville to the southwest. Although Mississauga was initially a car-centric city, significant strides have been made to improve walkability and add cycling lanes, with most major arteries having bi-directional bike lanes. The city's downtown is home to several transit hubs, such as Square One Bus Terminal, and the City Centre Transit Terminal. With a population of 717,961 as of 2021, Mississauga is the seventh-most populous municipality in Canada, third-most in Ontario, and second-most in the Greater Toronto Area (GTA) after Toronto itself. However, for the first time in its history, the city's population declined according to the 2021 census, from a 2016 population of 721,599 to 717,961, a 0.5 per cent decrease.
