Annual Safe Drinking Water Test Results

The safety of our students and staff is our top priority. The Toronto District School Board (TDSB) tests drinking water sources at its 583 schools on a regular basis, in alignment with provincial regulations. On July 1, 2017, the Ministry of Environment, Conservation and Parks (MECP) formerly known as the Ministry of Environment and Climate Change, amended Ontario Regulation 243/07 (Schools, Private Schools and Child Care Centres) under the Safe Drinking Water Act, introducing new requirements for the annual testing, from May to October, of drinking water sources.

Based on the current regulation, school boards need to test all designated drinking water sources at a school over a three-year period (elementary schools and childcare centres), and a five-year period (high schools). Water samples are taken between May and October and are analyzed by an independent laboratory certified by the Ministry of Environment, Conservation and Parks (MECP).

 

Test results for lead in drinking water will be posted on an annual basis consistent with our commitment to increase transparency and accountability. It also aligns with the TDSB’s Open Data initiative aimed to implement an online platform where the public can access published Board data on our Open Data Webpage .
