Annual Butterfly Festival at Tommy Thompson Park

Saturday, August 21, 2021

Late August is the prime time to get a glimpse of the Monarch Butterfly before they start their annual migration to Mexico, where they spend the winter. This incredible 3,500 km migration takes place between August and November and begins with the gathering of the Monarchs at places like Tommy Thompson Park, Toronto’s Urban Wilderness.

On Saturday, August 21, 2021 the annual Tommy Thompson Park Butterfly Festival will celebrate this incredible migration by welcoming children, families and nature lovers to learn more about butterfly conservation and biodiversity. Through the many activities, nature hikes and educational displays at this year’s FREE event, visitors can discover the more than 55 species of butterflies and moths recorded to date at the park.
