This interactive map provides the first provincial view of the more than 970 wellhead protection areas and 150 intake protection zones within the source protection areas in Ontario.  You can access over 20 layers of information every time you do a customised search.

For the first time, the public will be able to see the wellhead protection areas and intake protection zones of the lakes, rivers and aquifers that supply their drinking water.  This tool provides them with information needed to make informed property-based decisions.  As well, this tool will help ministries and other agencies implement source protection plan policies.

A link to the map can be found in the updated General Messages page of the Source Water Protection Resource Catalogue available on Conservation Ontario’s website.
