During the 2000s, the Exhibition Place grounds has seen several proposals for new uses. In July 2005, the City of Toronto asked for aquarium proposals from private enterprises. The only two respondents, Ripley Entertainment and Oceanus Holdings, suggested that they would be interested provided the location was closer downtown or had better transit access and parking. When the City of Toronto was considering the construction of a permanent casino, the CNE was the site of several proposals. The aquarium was built next to the CN tower and the City chose not to build a permanent casino.
