The Canada Southern Station (CASO Station) in St Thomas Ontario was the largest of 31 railway stations built in Ontario during the 1870s by Canada Southern Railway Company (CSR). The station was constructed between June 1871 and April 1873.
CASO Station was remarkably large for a town the size of St Thomas (the community didn’t become a city until 1881). However, the building needed to be big enough to accommodate both the town’s passenger station (ground floor) and the corporate headquarters of CSR (upper floor).
The building’s grandeur was impressive. The 1882 publication Picturesque Canada reported that the station was “one of the finest in the Dominion, and reminds one of the large structures in Chicago and New York.”
