Ports Toronto is responsible for maintaining a safe and navigable harbour as well as cleaning up the waters under their jurisdiction.
The majority of the harbourfront edge from Portland St to York St is the jurisdiction of the Harbourfront Centre and their Marine division is responsible for maintaining and cleaning this area.
The York St. slip is maintained/cleaned by both Harbourfront Centre and the Toronto Port Authority.
If debris is fronting a City waterfront park or reports of graffiti on a break wall in Lake Ontario, the parks supervisor will inspect and make necessary arrangements to have this cleaned up, call 311 to be referred to the parks supervisor.
