The Canadian National Railway (CN) Bala Subdivision is a major railway line in Ontario, Canada. It runs between the provincial capital of Toronto in Southern Ontario and Capreol in Northern Ontario, where the line continues as the Ruel Subdivision. It forms part of CN's transcontinental mainline between Southern Ontario and Western Canada.
Passing to the east of Lake Simcoe, the line bypasses the cities of Barrie and Orillia, instead passing through the community of Washago. Cutting west toward Georgian Bay, it parallels the Canadian Pacific Railway's MacTier Subdivision through Parry Sound country, penetrating into the more rugged terrain of the Canadian Shield.
