The Humber River watershed, the largest river system in the Toronto region, covers 903 square kilometres. From its source on the Oak Ridges Moraine and Niagara Escarpment, the Humber flows through outstanding natural habitats in rural and urban landscapes, to Lake Ontario. At least 12,000 years ago, the watershed was home to Aboriginal Peoples. They established an overland route along the river corridor to the Canadian interior. Later, European explorers and settlers used this route they called the Toronto Carrying-Place trail. Today, the Humber provides recreational and educational opportunities and a spiritual retreat for thousands of people of many different cultures.
This plaque commemorates the designation of the Humber River as a Canadian Heritage River and honours those people - past, present and future - who work to protect and enhance the Humber's heritage and recreational resources.
