For a number of geographical reasons, and also due to the proximity of the Rideau Canal, the town of Smiths Falls became a major focal point for both the CPR and the CNoR. Each used a mix of existing regional rail lines and new construction to build their networks. CP purchased the 1859-era Brockville and Ottawa Railway, a line from Brockville-Smiths Falls-Sand Point/Arnprior with a branch Smiths Falls-Perth (the latter joining CP's Ontario and Quebec Railway line to Toronto). CNoR built a 1914-era main line from Ottawa-Smiths Falls-Sydenham (to join an existing Bay of Quinte Railway line extending westward via Napanee-Deseronto). By 1887, the CPR had extended its Toronto-Smiths Falls mainline to reach Montréal; in 1924, 1600 CPR workers were employed in Smiths Falls.
