Formed in 1988, TEA provides an activist voice on environmental issues affecting Toronto, Ontario.
Its mission is to promote a greener Toronto and its vision is a green, healthy and equitable city with economic activity that sustains our environment.
TEA acts as an environmental watchdog at Toronto City Hall.
In April 2012, TEA adopted a new tagline: "a greener Toronto for all".
