Clean Water Act

The Clean Water Act ensures that communities can identify potential risks to their drinking water supplies, and take actions to reduce these risks.  It brings members of the public together with:

  • municipalities
  • conservation authorities
  • industry and business
  • community groups
  • farmers and landowners

to meet common goals to keep Ontario’s drinking water safe.
