2005

In 2005, Ontario’s electricity system was a major contributor of greenhouse gas emissions, air pollution and smog.

In 2017, Ontario’s system was 96% emission-free. Ontario’s clean electricity system is the key to our energy future…

April 2018 The Honourable Dave Levac Speaker of the Legislative Assembly of Ontario Room 180, Legislative Building Legislative Assembly Province of Ontario Queen’s Park Dear Speaker, In accordance with section 58.1 of the Environmental Bill of Rights, 1993 (EBR), I am pleased to present Volume One of the 2018 Energy Conservation Progress Report of the Environmental Commissioner of Ontario for your submission to the Legislative Assembly of Ontario. The 2018 Energy Conservation Progress Report, my independent, non-partisan review of Ontario’s progress in conserving energy, will be issued in two separate volumes. This first volume examines the impacts of Ontario’s transition to a low-carbon electricity system. The second volume, to be released later in 2018, will focus on the progress of energy conservation programs in 2016. In summary, Ontario can be proud of its cleaner, more reliable electricity system, and the resulting improvement in air quality and public health. Since 2005, we have taken the first, indispensable steps in building a low-carbon economy: conservation and minimizing fossil fuel use in electricity generation. Looking ahead, much more conservation and low-carbon electricity will be needed to displace fossil fuels as the climate crisis continues to worsen. Ontario is not yet preparing seriously for this future. Sincerely,

Dianne Saxe Environmental Commissioner of Ontario
