Although the Map & Data Library is physically closed, we are still available remotely and happy to help. We can conduct consultations using online teleconferencing software. Please feel free to contact us at mdl@library.utoronto.ca or use our help form. We have a number of tutorials available, are still supplying software licenses, and have compiled a list of resources for working with COVID-19 data.

Air photos

About the collection

Aerial map of Toronto 1960

The Map & Data Library has thousands of paper air photos and terabytes of digital imagery in its air photo collection, primarily of the Toronto region, but also for selected locations in Ontario and Canada. We have coverage available for the City of Toronto at 1:5,000 scale for alternate years from 1972 to the present, with 1:500 coverage of the former municipality of Toronto from 1967-68 onwards. Recent air photos come in digital format and are available only to University of Toronto faculty, staff and students due to licensing restrictions.

To find out what years are available for a particular location, consult the Air Photo Collection Listing, a comprehensive inventory of the collection by place name. You may also wish to consult our Remote Sensing Resources page as well.
