Waterloo is a city in the Canadian province of Ontario. It is one of three cities in the Regional Municipality of Waterloo. 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".
