Humber Bay Butterfly Habitat
The Humber Bay Butterfly Habitat (HBBH) is an ecological restoration project that provides critical habitat for a variety of native butterfly species. Located along the shores of Lake Ontario in Toronto's west end, HBBH incorporates a diversity of native wildflowers, shrubs, trees, grasses, hedges and a variety of physical features known to support butterflies throughout their life cycles. Interpretive features explore the relationship between butterflies and their natural habitat. The goal of the HBBH is to establish a self-sustaining native plant community which will support a variety of butterfly species, while educating park users about the value of urban conservation.

The City of Toronto is committed to keeping the Humber Bay Butterfly Habitat healthy and meadows require regular maintenance including mowing, planting, and invasive species control. In the summer of 2018, the City is implementing targeted invasive species herbicide treatment followed by native wildflower planting.

Best time to see the butterflies
A large variety of native butterfly species will inhabit HBBH during the months of April to mid October. While we do not stock the park with butterflies, we can suggest the best weather conditions to see butterflies in action. It is best to visit when it is not too hot, windy or raining. For example, in the summer months, early morning or early evening (as opposed to mid-day when it is the hottest) would increase your chances to see butterflies. For monarch butterflies, the first three weeks in September (late summer to early fall) is a good time to visit the garden to see a large group of monarch butterflies. At this time of the year the monarchs 'stage' in large numbers as they prepare for their winter migration to central Mexico.

Getting Involved
Throughout summer, the HBBH Community Stewardship Team works to maintain and monitor the habitat. To get involved or for more information, contact staff in the Natural Environment & Community Programs office at, or visit the City of Toronto Parks, Forestry and Recreation website.
