Grand Trunk Railway Prescott
The Grand Trunk was incorporated in 1853 to run from Sarnia to Portland, Maine. Although it took over existing lines, new ones had to be built, including sections of the key Toronto to Montréal line completed by the noted English engineering firm of Peto, Brassey, Jackson and Betts in 1856. The Prescott station, built about 1855, is a typical example of the smaller stations erected by this firm for the Grand Trunk Railway. Influenced by English designs, the station is an enduring monument to early Canadian railway enterprise.
