In Canada, a number of communities have developed and operated district energy systems for decades. The oldest system is in London, Ontario, and dates back to 1880.

In Ontario, district energy systems are currently in operation in Markham, Windsor, Kingston, London, Ottawa, Toronto, Barrie, Sudbury, Cornwall, Oshawa, Mississauga, and Hamilton.

In Guelph, two district energy facilities are currently in operation at the University of Guelph and the Sleeman Centre. Additional district energy facilities are under development in the Hanlon Creek Business Park, at the West End Community Centre and at Guelph General Hospital.
