Canadian Olympic swimming champion Maggie Mac Neil is retiring.

The gold medalist in the women’s 100-meter butterfly at Tokyo’s Summer Games in 2021 announced the move on social media Thursday in a post that included a photo of her swimming as a child.

“The little girl above would have never dreamed this is where her love of swimming would take her,” Mac Neil wrote. “I am so grateful for all the memories, people, and places I have gotten to experience just through swimming.
