The Toronto Green Standard Version 3 includes a consolidated Standard for high performance city building projects. This Standard applies to all non-residential development being planned and built by the City’s Agencies, Corporations & Divisions. City-owned residential buildings apply the Mid-High Rise Residential Standard e.g. Toronto Community Housing and Create TO.

The new City Standard includes minimum, required Tier 2 level performance measures and, higher, voluntary performance tiers and targets in some categories to achieve Toronto’s low carbon pathway. The Version 3 Standard applies to all city-owned buildings and additions greater than 100 m² GFA commencing in 2018 with the 10 year Capital budget and Plan within all procurement processes.  City building projects must be third-party verified post-construction. Select a prequalified evaluator from the City’s list. Evaluators conduct a two-stage review during construction documentation and post construction and submit a Verification Report for approval by Environmental Planning.

City Agencies, Corporations and Division-owned facilities are also required to be net-zero energy and emissions by 2026 (Transform TO Council approved climate targets).

See the City Council Decision to adopt a Toronto Green Standard Tier 2 policy for City-owned and ACD buildings from March 28, 29, 2017 for details.
