ION is the Region of Waterloo's rapid transit system. ION is made up of light rail transit (LRT) and bus rapid transit (BRT).
ION light rail consists of a 19-kilometre route from the Conestoga Mall transit terminal in Waterloo to the Fairview Park Mall transit terminal in Kitchener, with 19 stops in between.
ION BRT features a 17-kilometre route from the Ainslie Street transit terminal in Cambridge to the Fairview Park Mall transit terminal in Kitchener. ION BRT service began operating in September 2015. Stage 2 ION will see the ION BRT route converted to LRT, creating a seamless route of light rail that stretches from Cambridge to Waterloo.
When ION light rail launches in 2018, GRT riders can easily transfer for free between bus and train services.
