CONSULTATION

Members of the public, agencies and other interested parties are encouraged to participate in the Environmental Assessment process by attending consultation opportunities or contacting the project team directly with information, comments or questions. Consultation opportunities are planned and will be advertised on the project websites, in local newspapers and via direct mail. A second round of joint Public Open Houses are planned for winter 2014 to present and seek feedback on both the TPAP (Metrolinx) and Class EA (Hydro One) project components.

Consultation with the public, review agencies and First Nations and Métis communities is a key component to the UP Express Electrification EA.
