There are many native pollinators in Toronto most people don't know about, and lots of them are found in the park!
The Parkdale and Toronto Horticultural Societies help with the old-fashioned garden in Colborne Lodge, and their Pollinator Gardens Project has made a pollinator garden right in the park where you can see native plants and native pollinators together. You can find dates when tours of the pollinator garden will be held in the park at their Events page.
