The Ontario Southland Railway, Inc. is an independently held short line operator. The company was founded in 1992 to purchase 27 kilometres (17 mi) of track between Tillsonburg and Ingersoll, Ontario from the Canadian Pacific Railway (CPR). In 2009, a second line was added, as 51 kilometres (32 mi) of CPR track from Woodstock to St. Thomas, Ontario were integrated into the system. In 2015, Ontario Southland began leasing the ex-Canadian National Cayuga Subdivision between St. Thomas and Delhi, Ontario, which had been abandoned by its former shortline operator the St. Thomas and Eastern Railway in 2013.
OSR also operated the Guelph Junction Railway until 28 August 2020 when operations were transferred to the Goderich–Exeter Railway.

### Cayuga Subdivision

In November 2015, OSR and Canadian National (CN) Railways made a joint announcement regarding the transfer of operations on CN's disused Cayuga subdivision. The responsibility of managing the St. Thomas–Tillsonburg segment (and extending to Delhi, Ontario) was handed over to OSR. However, this transition would commence after essential track maintenance was carried out, aiming to facilitate the transportation needs of a newly established windmill turbine factory situated east of Tillsonburg. Other customers served include two grain elevators in Courtland, Ontario, an ethanol plant in Aylmer, Ontario and a fertilizer plant in Delhi.
