Finding Air Photos
To find out what years are available for a particular location, begin by consulting the Air Photo Collection Listing, a comprehensive inventory of the collection by place name.
Recent air photos come in digital format and are available only to University of Toronto faculty, staff and students due to licensing restrictions. All our digital air photos are catalogued in the Geospatial Data Inventory. You can browse through all digital air photos, or Toronto digital air photos.
