December 18, 2015 – The Ministry of the Environment and Climate Change today released the Minister’s Annual Report on Drinking Water 2015 and the Chief Drinking Water Inspector’s 2014-2015 Annual Report.

More than 80 per cent of Ontario residents get their drinking water from municipal residential drinking water systems.  This year’s report indicates that Ontario’s municipal drinking water continues to be of high quality and is well protected.

In 2014-2015, all 662 municipal residential drinking water systems were inspected:

  • 99.8% of more than 533,000 test results from municipal residential drinking water systems met Ontario’s strict drinking water quality standards
  • 99.4% of municipal residential drinking water systems received an inspection rating greater than 80 per cent
  • 67% received an inspection rating of 100 per cent.

April 22, 2015 – Ontario’s Chief Drinking Water Inspector’s 10th Annual Report suggests Ontario’s municipal drinking water is among the best protected in the world. The report provides detailed information about the quality of municipal water including the number of samples analyzed and the chemicals they are tested for. Municipal residential drinking water systems serve more than 80 per cent of Ontario’s population.

Note the Water Inspector DOES NOT comment on the quality or protection afforded to Ontario’s lakes and rivers, unless the water is used directly as municipal sources of drinking water.
