Infrastructure Planning and Permits

Toronto and Region Conservation Authority’s (TRCA) Environmental Assessment Review and Permit process helps to protect people, property, and the watersheds we live in by taking an active role in planning and development for the region.

We review projects that affect our watersheds, and we regulate infrastructure development in or near valleys, streams and wetlands, and along the Lake Ontario shoreline.

Construction of infrastructure is considered development under the Conservation Authorities Act and a permit will be required if the infrastructure is proposed within a TRCA regulated area.

Environmental Assessment Review

Under the Planning Act and the Environmental Assessment Acts (federal and provincial), TRCA is a commenting agency and provides input on planning matters in various capacities.

For public infrastructure and large private infrastructure projects, Ontario’s Environmental Assessment Act is the principal review mechanism.

When the provincial Environmental Assessment Act was approved in 1975, conservation authorities were directed to provide technical clearance for natural resources management on applications made under the Act.

Technical advice is also sought from TRCA for applications made under the Canadian Environmental Assessment Act. The majority of TRCA’s environmental assessment review falls under the provincial process.

How to Apply for a Permit

TRCA regulates certain activities in and adjacent to watercourses (including valley lands), wetlands, shorelines of inland lakes and other hazardous lands.

TRCA issues permission for work in this area by issuing a permit under Ontario Regulation 166/06. This role is granted to TRCA under section 28 of the Conservation Authorities Act.
