Large Event Application
Mississauga Celebration Square is anticipated to undergo lifecycle infrastructure upgrades in 2028, resulting in a temporary closure of the venue for festival and event programming. As a result, the City will not be accepting applications for the 2028 event season, with the next application intake anticipated to open in September 2027 for 2029 events.
