55% of GHG emissions in the city of Toronto are attributed to homes and buildings ( 60% of that from residential buildings and 40% from commercial and institutional buildings). On July 14, Toronto City Council took one more step to address those emissions, by approving new building policies. As described in the City’s press release, the policies include a “Net Zero Existing Buildings Strategy to decarbonize all existing residential, commercial and institutional buildings within the next 30 years; a Net Zero Carbon Plan to reduce emissions in City-owned buildings; and an update to the Toronto Green Standard to achieve net zero emissions in new development by 2030.”
The Net Zero Existing Buildings Strategy: is expected to increase local building retrofit economic activity by 87 per cent over the next 30 years, and nearly double annual investment in existing buildings. It is also expected to create an additional 7,000 direct, full-time jobs in local construction, energy services and supportive work over 30 years. Further,
- it will begin with voluntary emissions performance measures and targets, transitioning to mandatory requirements in 2025, at which time it will require annual emissions performance reporting and public disclosure;
- Expand and enhance retrofit financing;
- Support workforce development and training;
- City Council will lead by example with a plan to retrofit all City-owned buildings to net zero emissions by 2040.
The Green Standard for New Buildings: Emissions reductions in new buildings will be regulated by the newly approved the Toronto Green Standard Version 4. The original Toronto Green Standard was introduced in 2010 and has been updated approximately every 4 years. The latest Version 4 addresses requirements for “building energy and GHG reduction and electric vehicle parking, and introduces tracking of embodied emissions in building materials used in construction. It addresses resilience through enhanced green infrastructure to manage stormwater runoff, reduce urban heat island impacts and promote biodiversity, including extensive and higher performance green roofs, bioswales, rain gardens, native pollinator species plantings and a new requirement for ”green streets” (roads or streets that incorporate green infrastructure).”
Version 4 will apply to new development applications beginning on May 1, 2022.
According to Mayor John Tory: “Implementing this strategy will also be essential to public health and resilience in the face of a changing climate. Extreme heat is already causing an average of 120 premature deaths annually, and this number is expected to double by 2050 without strong action. Retrofit measures such as improving building envelopes and installing heat pumps greatly reduce exposure to extreme heat and will ensure Torontonians are safe during increasingly frequent and severe heat waves.”

Canada’s Climate Retrofit Mission, published by Efficiency Canada in June 2021. Authors Brendan Haley and Ralph Torrie state that, at the current pace, it will take 142 years to retrofit all low-rise residential buildings and 71 years to retrofit all commercial floor area in Canada. The report emphasizes the urgency of the task and outlines market and policy innovations to speed up the process and achieve economies of scale to reduce costs.
Efficiency Canada also recently released Codes4Climate: A Building Code Advocacy Toolkit, to encourage net-zero energy performance through improvements to building codes across Canada.
