Every fall, monarch butterflies all across Canada start flying south. They travel thousands of kilometres, braving storms and food shortages, to make it to their wintering grounds in Michoacan, Mexico.

In this episode of This Is Wild, we’ll meet the iconic little insects that make this extraordinary journey every year. From the monarchs’ remarkable navigation skills to the dangers that put their migration at risk, we’ll uncover what these fragile travellers reveal about the health of the natural world.
