Ottawa Valley Railway (reporting mark RLK) is a Canadian railway that operates 150 miles (240 km) of track in the provinces of Ontario and Quebec, and is owned by Genesee & Wyoming Canada Inc., the Canadian subsidiary of Genesee & Wyoming Inc.[1] The railroad began operations on 30 October 1996 under the auspices of RaiLink Canada, and fell under the control of RailAmerica after that company bought RaiLink in July 1999.

[3] On July 23, 2012, Genesee & Wyoming Inc. announced that it intended to purchase RailAmerica in a deal valued at $1.39 billion.

As traffic was reduced on other CP routes, that railway was able to redirect trains onto its lines through Toronto, and RailAmerica's lease on the line to the east of Petawawa, Ontario ended in December 2009.

[9] The OVR interchanges with the Canadian Pacific at Sudbury, as well as with the Canadian National Railway at North Bay, Ontario, the Ontario Northland Railroad at North Bay, and the Huron Central Railway at Sudbury.

[2] The railway once hauled around 70,000 carloads a year, the majority of which came from CP's intermodal bridge traffic.
