The Archives has an extensive collection of architectural drawings from the 1840s to the present day. This collection includes floor plans for many of Toronto’s most significant buildings. The drawings show the floor plan layouts as they existed when the drawings were made, and do not necessarily reflect the way things are today.

Only a small percentage of our architectural drawings have been digitized, including such landmarks as Old City Hall, Casa Loma, and the Don Jail. Some of them are available here. Should you require copies of any plans, they must be purchased individually.

The Archives does not have plans for all buildings ever built in Toronto. If you require plans of buildings that are not in our collection, please contact Toronto Building.


For best performance, it is recommended to view these plans on a laptop or desktop computer.

For more plans and architectural drawings, some of which may not be available to view online, see the following series:
