Branch 20 is a generous supporter of Polish Youth organizations in Windsor such as the Polish School and Tatry Song and Dance Ensemble. We are also committed in supporting Canadian charitable organizations and Windsor hospitals. In the mid 1980’s, we sponsored a soccer team through Polonia Soccer Club and continue to provide an annual donation. Our members volunteer to raise funds for charitable causes and promote our Cultural heritage but we also spend time socializing.
We’ve participated in the Canada Day Parade and have held activities such as bowling tournaments and picnics at the Polish Beach. Members have enjoyed one day outings to Toronto, Niagara Falls, Stratford, Grimsby, Frankenmuth, Sea World in Ohio and skiing on Michigan slopes. Since 2005, a busload of members have traveled to Chicago, Washington, Montreal, Boston and New York for a 4 day holiday over the Labour Day Weekend.
