The Humber River is the only Canadian Heritage River in the GTA, and one of only 40 such designated rivers across Canada.
The Humber River was officially designated in 1999, under the Canadian Heritage Rivers System (CHRS) for its significant cultural and recreational values, thanks to the collaborative efforts of Toronto and Region Conservation Authority (TRCA), the Humber Heritage Community, and dedicated community members.

The Humber River has rich human history as a home for Indigenous peoples along its banks, as an ancient transportation route known as the Carrying Place Trail, and as a site for many of Toronto’s post-European settlement homes and industries.
The Carrying Place Trail is one of the oldest established transportation routes in Canada and is the highlight of the Humber’s CHRS designation.

The East Humber is 63 kilometres and originates in the kettle lakes region of Richmond Hill and King Township.
The West Humber begins in Caledon, in the rolling hills of the South Slope, and flows 45 kilometres over the Peel Plain in Brampton before joining the Main Humber in Toronto.
