Waterloo Region's Transit Corridor Growth Plan
In July 2009 The Transport Politic, a transit blog, reported on Waterloo Region's plans for light rail and a regional land use plan that would concentrate development along the transit line. The blog page could not be opened for this reference, so this entry sets out the documented history of the project that became Ion. Last checked: November 10, 2026.

Transit tied to land use
Wikipedia reports that in 2004 the Region began an environmental assessment of a rapid transit line, intended to provide higher-order transit and encourage more compact urban growth along the corridor. Development would gather around stations instead of spreading outward.
The 2009 decision
On June 24, 2009, Regional Council approved light rail as the technology and chose to build in stages, because ridership, development potential and costs vary along the route. Stage 1 runs through Uptown Waterloo and Downtown Kitchener. Cambridge would receive adapted bus rapid transit between Fairview Park Mall and Ainslie Street terminal, using shoulder bypass lanes on Highways 8 and 401. The vote was 15 to 1, with Cambridge mayor Doug Craig the dissenter. Funding commitments announced in summer 2010 were $300 million from Ontario and $265 million from the federal government.
Construction and opening
Construction began in August 2014. Late vehicle deliveries from Bombardier pushed service back, and the Ion light rail opened on June 21, 2019. The Cambridge section is served by the Ion Bus (route 302).
Cambridge and Stage 2
Stage 2 would extend rail from Fairway to downtown Galt. Cambridge council rejected a route plan in July 2017. In November 2025, Regional Council approved the light rail extension to downtown Cambridge over a bus option, with a projected 17 km of track. Construction timing is not confirmed.
