More than 3,000 Canadian Pacific Rail workers went on strike late Tuesday, their union said, even as contract negotiations continue. The nation's second largest railway said it would rely on managers to keep trains rolling, even though the strike is widely expected to curtail or shut down Canadian Pacific's freight shipments.
That would compound shipments already delayed at CP and its larger rival Canadian National Railway caused by extreme weather over the winter. The delays especially hit miners, loggers and grain farmers trying to get their wares to ports for shipping to overseas markets.
