About Us


With upwards of 18,000 members, the Power Workers’ Union has been diligently representing skilled workers in Ontario’s electricity sector for over seven decades. The PWU has grown over the years into one of the strongest, most flexible unions in Canada, evolving from an organization that was originally designed to represent employees at one company - Ontario Hydro - to a modern, multifaceted union that now represents members at companies throughout Ontario in over 55 separate bargaining units. The PWU is a knowledgeable and experienced player in the electricity sector, committed to delivering a promising future for our membership and continuing to help keep the lights on for all Ontarians.
