NEW! Class EA Amendments

THE GOVERNMENT HAS EXTENDED THE 45-DAY REVIEW PERIOD FOR INDIGENOUS COMMUNITIES UNTIL SEPTEMBER 22, 2020.


Class Environmental Assessment for Minor Transmission Facilities

A Class Environmental Assessment (Class EA) is an environmental planning process approved under Ontario's Environmental Assessment Act (EAA) for certain classes of projects that have predictable and manageable environmental effects. A proponent who receives approval for a class of undertakings does not need to obtain separate approval under the EAA for each specific project, provided the class planning process is adhered to for the specific project.

The Class EA for Minor Transmission Facilities was originally developed by the former Ontario Hydro and approved under the EAA by Order-in-Council in 1980. It has undergone several revisions since that time. The current version of the document, approved by the then Minister of the Environment and Climate Change (now Minister of the Environment, Conservation and Parks), is the 
C​lass EA for Minor Transmission Facilities (November 16, 2016).

The types of electricity infrastructure projects that may be planned according to the process set out in the Class EA for Minor Transmission Facilities are defined in the 
Guide to Environmental Assessment Requirements for Electricity Projects and in the following Ontario Regulations: Electricity Projects (O. Reg. 116/01), and Transit Projects and Metrolinx Undertakings (O. Reg. 231/08).


Class EA Amendment Process

On November 16, 2016, the then Minister of the Environment and Climate Change (now Minister of the Environment, Conservation and Parks) issued a decision on Hydro One's amended Class EA for Minor Transmission Facilities. Read the Minister's letter to Hydro One and the Minister's Notice of Approval, November 16, 2016.
 
More recently, as a result of the changes made to the Environmental Assessment Act via the More Homes, More Choice Act (2019), Hydro One is proposing 2020 amendments to the Class EA for Minor Transmission Facilities. The details of the proposed amendments can be viewed on this page.
 
Following completion of the current Class EA amendment process, Hydro One will plan to undertake a review of the Class EA every five years, or sooner should necessary changes be identified by Hydro One, or due to outcomes from the government’s EA Modernization program.
 

Monitoring the effectiveness of the class ea process

Hydro One is responsible for monitoring the effectiveness of the Class EA Process by ensuring that the document remains relevant and current. As noted in Section 5.5 of the Class EA Document, Hydro One will produce a consolidated annual monitoring report including information provided by all project proponents who use the Class EA in that calendar year. The report will be submitted each year on or before April 1st to the Ministry of the Environment, Conservation and Parks (MECP).


The 2019 Annual Monitoring Report was filed with the MECP on March 31, 2020. The MECP issued an Acknowledgement Letter to Hydro One on July 6, 2020 confirming fulfilment of the Notice of Approval.


All project proponents are required to provide their information for the annual monitoring report to Hydro One by February 25 of each year using the required reporting format provided in Appendix H of the Class EA document. Project proponents may submit their information by email to: ClassEA.AnnualMonitoringReport@HydroOne.com.
