Wood pole replacement projects are considered routine maintenance with relatively minor effects.


These types of projects are subject to the Class Environmental Assessment (EA) for Minor Transmission Facilities (Hydro One, 2016), in accordance with the Ontario Environmental Assessment Act. The Class EA is a streamlined planning process that has proven effective in ensuring that minor transmission projects that have a predictable range of effects have feasible environmental mitigation and/or protection measures in place. The Class EA process contains screening provisions that may apply to these projects.
