- Happyland Park 1906-1922, part of an amusement park located at the south side of Portage and Sherburn. The first game by the Winnipeg Maroons on May 24,1906 had a capacity of 4000 spectators. After Happyland closed in 1922...
- Happyland became Sherburn Park between June 1924 and 1942 where the Winnipeg Maroons played. Sherburn had a seating capacity of 3500.
- After Sherburn Park closed, Osborne Stadium operated from May 1932 until 1952 where the Winnipeg Blue Bombers played until the Winnipeg Stadium was built at Polo Park in '53, though Osborne was not modified for baseball until 1935.
