Toronto at
Exhibition Place and later moved to
Ontario Place theme park. In August 1994, it was awarded to
St. Marys, Ontario, and in June 1998 the doors officially opened in St. Marys.

The re-designed museum opened to the public on April 27, 2019. The Hall of Fame and Museum is dedicated to preserving Canada's
baseball heritage which dates back to June 4, 1838, when a game which very closely resembled today's game of baseball was played in
Beachville, Ontario. and extensively researched and validated the Beachville game in 1838. In 2021,
Helen Callaghan, who had played in the
All-American Girls Professional Baseball League (AAGPBL), became the first woman individually inducted to the Canadian Baseball Hall of Fame; the Hall had previously inducted, as a group in 1998, all Canadian women who played in the AAGPBL. In early 2022, the Hall of Fame was criticized for not inducting the
Chatham Coloured All-Stars, the first team of
Black Canadians to win an
Ontario Baseball Association title. ==Awards==
