Process and Timeline

The GTA West project is following Ontario’s process for an Individual Environmental Assessment under the Environmental Assessment Act, which are carried out for large-scale, complex undertakings with the potential for significant environmental effects and major public interest.

On May 3, 2021, The Federal Minister of Environment and Climate Change determined that the GTA West Transportation Project warrants designation under the Impact Assessment Act, and has issued an order and response. ​A decision on whether a federal Impact Assessment would be undertaken is expected in late 2021.  Read the letter from Ontario Minister of Environment, Conservation and Parks Jeff Yurek to Jonathan Wilkinson, Minister of Environment and Climate Change Canada.
