The Northlander was a passenger train operated by the provincially-owned Ontario Northland Railway in southwest and northeast Ontario, Canada. In 2012, rail service was discontinued and replaced with express bus service. Rail service will be reinstated in 2026 with an expanded route, greater frequency, new Siemens Venture train sets manufactured by Siemens Mobility Ltd., and various track and station upgrades. The new bi-directional route will run up to seven days a week from Toronto Union Station to Timmins, with an additional new rail connection from Timmins to Cochrane and express bus service from Matheson to Cochrane Station.
