Ontario Water Sector Strategy

Ontario’s standards for water treatment, testing, and reporting are as strong as – and often stronger than – those of other Canadian jurisdictions. This is based on the following:

  1. Ontario’s drinking water is among the best protected in the world based on independent jurisdictional assessments. (2017-2018 Annual Report from Ontario’s Chief Drinking Water Inspector)

  2. Ontario’s leadership in drinking water protection continues to receive high acclaim. We were the only province to receive an A rating in Ecojustice’s Waterproof 3: Canada’s Drinking Water Report Card.

  3. Ontario is the North American leader in implementing quality management in the management and operation of drinking water systems, and is recognized as a leader in providing safe drinking water. This is based on the following statistics from the Minister’s Annual Report on Drinking Water 2018:

    • 99.8% of tests from municipal residential drinking water systems met standards
    • 99.8% of 659 municipal residential drinking water systems received an inspection rating indicating compliance of over 80% with Ontario's regulations.  Seventy-five per cent of systems inspected has a perfect rating of compliance.
    • 99.6% of tests from systems serving designated facilities met standards

  4. Ontario’s certification and training requirements for operators are among the most stringent in North America.  As of December 31, 2019, there were 6,937 certified drinking water operators in Ontario.

  5. All municipal residential drinking water systems received their final licences and accreditation as part of a provincial licensing program. The program makes Ontario the first jurisdiction in North America to have mandatory quality management systems for all regulated drinking water systems.
