Over the years, Peterborough’s YMCA community offered dozens of clubs, including:
- The Peterborough YMCA Chess and Checkers Club, founded in 1958 and still active;
- The Triangle Club, a group of 12 young men who met on Tuesdays to educate themselves on “various aspects of the local government;”
- The Friday Night Supper Club;
- The Ladies Auxiliary.
The Ladies Auxiliary played an important role at the Peterborough YMCA. The women would meet monthly to discuss matters, such as the allocation of donations and fundraising, as well as to inspect the YMCA amenities and supplies, particularly for the dormitories and kitchen.
The Friday night Supper Club was, for many years, something of an institution. On Friday evenings, young men would pay 25 cents to enjoy dinner, musical acts prepared by the girls, and speakers. Club members grew close over the years, creating annual traditions, including dances, Christmas tree decorating, golf tournaments and much more. World War II brought tragedy, however: about 100 club members enlisted, and 25 never returned. The fighting in Europe aged the veterans beyond their years, it is said, and the post-war Friday Night Supper Club was never the same.
