'Toronto, Canada West [now Ontario], shewing existing & proposed
defences': map. Reference table. Scale: 1 inch to 880 yards [2 inches to 1
mile]. Compass indicator. Lithographed at the Topographical Depot, War Office.
Originally accompanied a report by Lieutenant Colonel Jervois, January 1865;
the report is not filed in WO 55/2281. This map was formerly filed, perhaps
erroneously, with maps illustrating defences in the United Kingdom.
