The Humber Arboretum consists of nearly 250 acres of public gardens and natural areas located in the Humber River watershed in North Etobicoke. Connected to Humber College North Campus, it exists as a unique tri-partnership between Humber College, the City of Toronto, and the Toronto and Region Conservation Authority (TRCA). The Humber Arboretum is free to visit and offers a variety of programming to both Humber College students and the general public.

Humber Arboretum is a thriving natural ecosystem and outdoor learning space that advances the highest potential and well-being of the community through strengthening our relationships with nature and with each other.


Together we:

  • Protect and care for our natural world in ways that continually model leading practices and motivate others to emulate and further develop these practices.
  • Facilitate nature-based experiences and nurture environments that foster learning, spark innovation, and inspire action.
  • Connect people with nature to benefit the health of both and uplift the well-being of communities.

 As defined in the Humber Arboretum 2019 to 2024 Strategic Plan.

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.
