There is no mention in Bill C-49 of discontinuing rail lines or of allowing a railway company to discontinue an existing line within 60 days. If a line was active, however, the service level could be raised by the Canadian Transportation Agency. In many cases, the lines that railway companies decide to shut down have not been used for a number of years. It costs them money to maintain those lines. The bill does not cover this issue, but if a line is in active use, it is certainly in the interest of our category 1 rail companies to maintain it, as that gives them better access to transportation business.
