Any efforts by the federal government to bring the rail lockout to a close will not have the support of the federal N-D-P.
Leader Jagmeet Singh says he will not support back-to-work legislation or any interference in the bargaining process involving Canada's two biggest railways.
Singh says he thinks Canadian National Railway and Canadian Pacific Kansas City expect the Liberals to ``swoop in to help the corporation and hurt the workers with binding arbitration or back-to-work legislation."
Prime Minister Justin Trudeau says his government will have more to say soon on what it will do to ensure a quick solution to the conflict.
Meanwhile, experts say a major rail work stoppage in Canada will have an effect on the country's economy.
C-I-B-C senior economist Andrew Grantham says a one-week lockout would lower the third-quarter annualized gross domestic product by about 0.4 per cent
He says that figure would more than double if the dispute stretches to two weeks, as more sectors would be forced to stop production.
The railways were expected to return to the bargaining table today with the union representing 93-hundred railworkers who were locked out overnight.
