A Neighbourhood Liaison Committee (NLC) was formed to provide interested residents and businesses an opportunity to discuss plant issues with City of Toronto staff. Committee members also have the opportunity to provide input on issues related to the plant that could affect the surrounding community, such as proposed changes to the facility.
