Wiarton Willie

Wiarton Willie is the name given to a Canadian groundhog who lives in the community of Wiarton in Bruce County, Ontario. Every February 2, on Groundhog Day, Willie takes part in the local Wiarton Willie Festival. His role is to predict whether there will be an early spring. Although the original Wiarton Willie died in 1999, the Wiarton Groundhog Day celebrations continue each year with a successor of the original Willie (except in 1999 and 2021 where, due to the previous Willies' deaths, no groundhog was used), and each successor is also referred to as Wiarton Willie.

Groundhog Day, featuring Wiarton Willie, is a popular annual festival in Wiarton and is similar to events in other locations in North America. A midwinter celebration involving an animal with predictive powers was an element of Celtic culture. The link between weather prediction and the day is said to have been inspired by an old Scottish couplet: "If Candlemas Day is bright and clear/ There'll be two winters in the year."
