Historical Maps of the St. Pierre River

Historical maps to locate the St. Pierre River. 

This map, showing the St. Pierre River (in 1696?), is found in a history of Loyola College; you can see
the river on the top right and how it forms the Petit Lac St. Pierre in the bottom foreground. 

Map from 1739; you can see the St. Pierre River beginning on Mount Royal, 
going through present-day Cote St. Luc and Montreal West, then forming a lake
in what were the Turcot train yards before emptying out at the St. Laurent River.

Another old map, from 1744, showing the Island of Montreal, surrounding areas, and St. Pierre River.

Here is a contemporary map showing the St. Pierre River highlighted in purple.
