London is a city in southwestern Ontario, Canada, along the Quebec City–Windsor Corridor. The city had a population of 422,324 according to the 2021 Canadian census. London is at the confluence of the Thames River, approximately 200 km (120 mi) from both Toronto and Detroit; and about 230 km (140 mi) from Buffalo, New York. The city of London is politically separate from Middlesex County, though it remains the county seat.

London is a regional centre of healthcare and education, being home to the University of Western Ontario (which brands itself "Western University"), Fanshawe College, and three major hospitals: Victoria Hospital, University Hospital and St. Joseph’s Hospital. The city hosts a number of musical and artistic exhibits and festivals, which contribute to its tourism industry, but its economic activity is centered on education, medical research, manufacturing, financial services, and information technology.
