“City of Verdun (Montréal)” print by The Underwriter's Survey Bureau Ltd. (1922)

At one point Verdun was much more than a part of Montréal—before 2002 it was its own city with its own rules, and at one point it was even the third largest city in Québec. Here I have a cleaned up version of a fire insurance map of Verdun, and it shows the city as it stood at time, resting between the aquaduct in the north, the St-Lawrence in the south, Fayolle Ave. in the west and "Tail Race" (roughly where Autoroute 15 currently runs) in the east.

If you dig into the BAnQ collection of fire insurance plans right here, you should be able to zoom in on any of a number of smaller zones on the map, depending on where their digitization program is at. Is this kind of map a useful tool for historians? You bet.
