Seven conservation areas instead of 36


 

Ontario is merging 36 conservation authorities into seven.


They are Western Lake Ontario, Central Lake Ontario, Eastern Lake Ontario, St. Lawrence, Lake Erie, Huron-Superior and Northern Ontario.

Western Lake Ontario

Covers the western Lake Ontario shoreline from Niagara through Halton and Peel. This would include parts of Brampton, Hamilton, Mississauga and Toronto.

Central Lake Ontario

Covers most of Toronto and much of the surrounding area from York Region through to Peel Region, Durham and part of the Kawarthas. Brampton and Mississauga are partly included.

Eastern Lake Ontario

Covers areas draining into eastern Lake Ontario and the Bay of Quinte. This would include Belleville, Oshawa and Peterborough.

Huron-Superior

Covers watersheds including Lake Huron’s northern shore and the Lake Superior basin. This would be the authority for Barrie, Owen Sound and Thunder Bay.

Lake Erie

Covers southwestern Ontario, including watersheds draining into Lake Erie. This would include Kitchener-Waterloo, London, Sarnia and Windsor, plus some of Hamilton.

 

St. Lawrence

Covers watersheds flowing into the St. Lawrence River. This would include Cornwall, Kingston and Ottawa.

Northeastern Ontario

Spans parts of Northern Lake Huron and the Upper Ottawa River systems, including North Bay, Sault Ste. Marie, Sudbury and Timmins.

Farmers risk losing pioneering programs launched by the Grand River Conservation Authority to provide financial and technical support for manure storages, soil erosion abatement, stream protection and tree planting.
