On August 20, 2022, join Toronto and Region Conservation Authority (TRCA) and organizations across Canada as we celebrate the start of the migration of the monarch butterfly.
Monarchs are a species at risk, threatened by climate change, urbanization, and loss of habitat, among other things. Yet every year, in late August through September, they undertake an incredible journey that takes them to the mountains of Mexico where they spend the winter.
Descendants of the butterflies that leave here in late summer will return the next spring to grace our summers with their presence.
Help draw attention to the need to protect monarchs by celebrating Flight of the Monarch Day!
