Cambridge (2006 population 120,371) is a city located in Southern Ontario at the confluence of the Grand and Speed rivers in the Region of Waterloo, Ontario, Canada. It is an amalgamation of the City of Galt, the towns of Preston and Hespeler, and the hamlet of Blair.

Galt covers the largest portion of Cambridge, making up the southern half of the city. Preston and Blair are located on the western side of the city, while Hespeler is in the most north-easterly section of Cambridge.

In 1988, Toyota Motor Manufacturing Canada opened a plant in Cambridge, which employed 4,518 people as of December 2005 and is the City's largest employer. Although beneficial to the City, traffic issues caused by slow-moving and long trains passing through main traffic routes to deliver material to and from the plant have caused some frustration for residents and emergency responders. Several other industrial companies also have locations in Cambridge, including Gerdau Ameristeel, ATS Automation Tooling Systems, Loblaw Companies Limited, Challenger Motor Freight Inc., Sutherland-Schultz Inc., Canadian General-Tower Ltd., iQor, Frito-Lay Canada (formerly Hostess), Babcock and Wilcox, Northstar Aerospace, Rockwell Automation, Com Dev and Northern Dynamics.
