The Humber Arboretum was created

September 1977

The Humber Arboretum, a 260-acre outdoor environmental laboratory and recreational playground, began operating after Humber College entered into a joint venture with the Borough of Etobicoke, the Metropolitan Toronto and Regional Conservation Authority, and the Metropolitan Parks Department.  It is situated on the west branch of the Humber River, extending from the Clareville Dam to Highway 27.
