The CNE has been host to four grandstands since its inception. The third grandstand, designed by G. W. Gouinlock, was built in 1907 and had a capacity of 16,000. It burned down in 1946, subsequently leading to the construction of the fourth (known as CNE Grandstand), built in 1948. Designed by architects Marani and Morris, this building was the first of what would prove to be several Modernist buildings built on the CNE grounds, its distinctive and bold cantilevered truss roof dominating the grounds for over 50 years. It initially housed 22,000 people, but was expanded over the years to a maximum of 54,000 in order to accommodate the additional seating required for major professional sports teams who made CNE Grandstand their home. It became the home base for the Toronto Argonauts football team, and later, to the Toronto Blue Jays baseball team. Architect Bill Sanford designed the alterations for baseball in 1976.
