Part
of the east end community Similar to Toronto Water’s other treatment plants, the R.C.
Harris is built along the shoreline of Lake Ontario and integrated
into the local neighborhood.
One way the
City and the neighborhood stay in touch is through the Public
Advisory Committee (PAC). Committee members play an important
role in the community and advise City staff on plant issues.
The City also
publishes a community newsletter called R.C.
Harris Times, featuring current and local topics related to
the plant. Public meetings on proposed changes to the site provide
other opportunities for the City to connect with community issues.
