On the Line is a 2011 Canadian documentary by Frank Wolf that investigates the risks and consequences associated with the proposed Enbridge Northern Gateway Pipelines project. The film is set in the context of a 2,400 km biking, hiking, rafting and kayaking journey that two friends embark on from the Alberta oil sands to the British Columbia coast. As the pair travel the proposed pipeline route, they encounter a broad cross-section of people who voice their perspective on the issues associated with the project.
