Toronto Architecture: Buildings Worth Looking Up For

In our view, Toronto is a city to look up in. This guide brings together our architecture coverage: walking routes through Cabbagetown and downtown, City Hall, Art Deco towers, the CN Tower, the Toronto Reference Library, the R.C. Harris Water Treatment Plant and the open-door weekend that lets you into more.

Some of the easiest access is free and official. Each May, Doors Open Toronto invites the public to explore the city's most-loved buildings and sites, free of charge, including rare access to buildings that are not usually open to the public. The next edition returns on May 29 and 30, 2027. Between festivals, the City's history museums keep older Toronto on view: Mackenzie House is a restored 1858 townhouse and the final home of William Lyon Mackenzie, Toronto's first mayor.

We caption a building with what a source can prove and call the rest opinion. Pick a route, tilt your head back and enjoy it.
