Ontario schools welcome students back with allowable lead limit twice as high as Ottawa’s guideline

Einem Bericht der Canadian Environmental Law Association (CELA) vom März 2026 zufolge überschreiten zahlreiche Schulen in Ontario, insbesondere im Ottawa Carleton District School Board sowie im Dufferin-Peel Catholic District und Peel District School Board, die Grenzwerte für Blei im Trinkwasser. Viele Schulen überschreiten sowohl den strengeren kanadischen Richtwert von 5 ppb als auch den weniger strengen provinziellen Grenzwert von 10 ppb. Eltern in den betroffenen Regionen, darunter Ottawa und der Peel Region (Brampton, Mississauga), ergreifen Vorsichtsmaßnahmen, indem sie ihren Kindern abgefülltes Wasser mitgeben.
