It contains the cities of Cambridge, Kitchener and Waterloo (KWC or Tri-Cities), and the townships of North Dumfries, Wellesley, Wilmot and Woolwich. Kitchener, the largest city, is the seat of government.
The region is 1,370 square kilometres (530 sq mi) in area, with a population of 587,165 as of the 2021 Canada census, though an end of 2023 estimate puts the population above 673,910 people. Waterloo Region forms the tenth-largest metropolitan area in Canada, with recent population growth almost entirely fuelled by international students.
The region was formerly called Waterloo County, created in 1853 and dissolved in 1973. The county consisted of five townships: North Dumfries, Waterloo, Wellesley, Wilmot, and Woolwich.
