They have their 'Punxsutawney Phil' - we have our 'Wiarton Willie', and there are others that have joined in recently like 'Dundas Donna' of Toronto and la marmotte de Québec, 'Fred'...
Groundhog Day is a traditional holiday originating in the United States that is celebrated on February 2. According to folklore, if it is cloudy when a groundhog emerges from its burrow on this day, then the spring season will arrive early, some time before the vernal equinox; if it is sunny, the groundhog will supposedly see its shadow and retreat back into its den, and winter weather will persist for six more weeks.
Groundhog Day was adopted in the U.S. in 1887. Clymer H. Freas was the editor of the local paper Punxsutawney Spirit at the time, and he began promoting the town’s groundhog as the official "Groundhog Day meteorologist".
The largest Groundhog Day celebration is held in Punxsutawney, Pennsylvania, with Punxsutawney Phil. Groundhog Day, already a widely recognized and popular tradition, received widespread attention as a result of the 1993 film Groundhog Day.
