A snapshot sealed into the CN Tower
The time capsule inside the CN Tower was built into the structure rather than placed on public display. During construction, letters, newspapers, and currency were sealed behind the observation deck’s concrete walls. The tower itself became the container: once the surrounding concrete was in place, the contents were hidden from view and protected within the building.
What the contents preserve
Each item records its era in a different way. Letters carry people’s own words; newspapers show what was being reported; and currency captures the designs and money in everyday circulation. Together, they offer a small, tangible record of the world around the tower while it was being built—not just a record of the engineering project.
That makes the capsule a quiet contrast to the observation deck above it. Visitors look out over Toronto from a space designed for a view, while behind the concrete is a deliberately unseen view of the past: ordinary objects set aside for people who would encounter them later. The tower holds both perspectives in one place, with the city’s changing skyline outside and a snapshot of its construction era sealed within.
