The Humber Arboretum exists to establish and maintain living plant collections, demonstrate correct horticultural and arboricultural techniques, conserve and restore natural areas and wildlife, facilitate research and education, and provide a welcoming space for people to gather.


The idea for the Humber Arboretum began in 1972, when horticultural students from Humber College saw undeveloped land beside the campus as an opportunity to practice their skills. It officially opened in September 1977 as a joint venture between Humber College, Toronto and Region Conservation, the City of Metropolitan Toronto, and the City of Etobicoke.
