Take advantage of the rare chance to see sections of the CN Tower usually hidden from public view as the landmark joins Doors Open Toronto for the first time during its 50th anniversary celebrations.
The special behind-the-scenes tours will run May 23 and 24, with guided sessions taking place every 30 minutes from 10 a.m. to 3:30 p.m. Created specifically for Doors Open Toronto 2026, the experience gives guests access to operational and architectural areas that are normally off-limits.
Along the way, visitors will learn how the tower functions behind the scenes and how it has changed since opening in 1976. The tour also includes archival footage, historical artifacts and stories tied to the tower’s role in shaping Toronto’s skyline over the past five decades.
