Key Takeaways:

Canadian Pacific Kansas City faces a potential strike by about 300 signal and communications workers after the union issued a 72-hour notice, threatening freight movement across Canada's rail network.
"We remain committed to bargaining in good faith with IBEW in order to reach a negotiated outcome," CPKC said in a statement Wednesday, adding that it has prepared contingency plans to continue serving customers and the Canadian economy.
The International Brotherhood of Electrical Workers Canadian Signals and Communications System Council No. 11, which represents employees maintaining signals and crossing systems, said it intends to strike at 08:00 MDT Sunday, May 31. CPKC said it has made wage and benefit proposals consistent with collective agreements already in place with its other unions across Canada.
A work stoppage at CPKC, which operates about 20,000 route miles linking Canada, the U.S. and Mexico with about 20,000 employees, could disrupt supply chains across North America. The railway provides critical freight service to ports from Vancouver to Atlantic Canada to the Gulf Coast to Lazaro Cardenas, Mexico.
The strike notice comes as CPKC, headquartered in Calgary, Alberta, has an "excellent track record of successful collective bargaining" with its unions across North America, the company said. Negotiations are expected to continue through the weekend.
The IBEW did not immediately respond to a request for comment on the status of talks.
The potential disruption follows a period of heightened labor tensions in Canada's transportation sector. The last major rail labor dispute in Canada, involving Canadian National Railway in 2024, resulted in a brief work stoppage that affected an estimated C$250 million in daily freight movements before the government intervened.
CPKC's contingency plans aim to ensure safe and efficient railway operations continue should a work stoppage occur, though the scope of any service reductions remains unclear.
