The CTC Source Protection Region

The CTC Source Protection Region contains 25 large and small watersheds and spans over 10,000 km2, from the Oak Ridges Moraine in the north to Lake Ontario in the south.  The region contains portions of the Niagara Escarpment, Oak Ridges Moraine, Greenbelt, Lake Ontario and the most densely populated region of Canada.

The region is complex and diverse in terms of geology, physiology, population, and development pressures. This results in many, often conflicting water uses including drinking water supply, recreation, irrigation, agriculture, commercial and industrial uses, as well as ecosystem needs. The CTC Source Protection Plan policies aim to ensure that we have enough clean drinking water to sustain all these activities now and for future generations.
The CTC Source Protection Region includes:

  • 25 local municipalities and eight single tier, regional or county municipalities
  • 66 municipal supply wells
  • 16 municipal surface water intakes on Lake Ontario

The Ontario Clean Water Act, 2006 (the Act) and the associated Regulations prompted the formation of the CTC Source Protection Committee (SPC), which is mandated to: undertake a technical assessment of current municipal water sources to identify vulnerable areas and existing and future threats that may impair the long-term sustainability of the source; and develop a Source Protection Plan containing policies which address significant drinking water threats to ensure the protection of the municipal drinking water sources and identifying who is responsible to implement each policy.

Some municipalities located in the CTC Source Protection area have been designated to implement CTC policies to protect municipal drink water supply, in addition to several provincial ministries. The Source Protection Plan policies aim to ensure that we have enough clean drinking water to sustain all these activities now and for future generations.
