Ontario Releases 2013-14 Chief Drinking Water Inspector’s Annual Report

Province’s Drinking Water Among Best Protected in the World

April 22, 2015

The 2013-14 Chief Drinking Water Inspector’s Annual Report confirms that Ontario’s drinking water is among the best protected in the world.

The report demonstrates that the province and municipalities continue to work together to ensure that drinking water systems in Ontario deliver safe, high-quality drinking water.

In 2013-14:

  • 99.83 per cent of drinking water tests from municipal residential drinking water systems met Ontario’s rigorous, health-based drinking water standards. These municipal residential drinking water systems serve more than 80 per cent of Ontario’s population.
  • 99.49 per cent of drinking water tests from systems serving designated facilities such as daycares, schools or health care centres met Ontario’s drinking water quality standards. The standards establish the maximum allowable concentration of chemicals and biological content that can be present in drinking water.
  • 72 per cent of all municipal residential drinking water systems fully met all regulated requirements including water sampling, testing and monitoring – a four per cent increase since 2012-13.

The Chief Drinking Water Inspector’s report is published annually and provides detailed information about the quality of water we drink including the number of samples collected and analyzed and the chemicals they are tested for.

Protecting the province’s clean drinking water and safeguarding our environment is part of the government’s economic plan for Ontario. The four-part plan is building Ontario up by investing in people’s talents and skills, building new public infrastructure like roads and transit, creating a dynamic, supportive environment where business thrives and building a secure savings plan so everyone can afford to retire.
