The country害羞草研究所檚 two main freight railways are turning away a growing number of goods ahead of a potential work stoppage next week that could snarl supply chains and disrupt industry.

Canadian National Railway Co. schedules show that, starting Friday, it is barring container imports that originate at some ports, including New York City.

CN and Canadian Pacific Kansas City Ltd. are also beginning to halt shipments that need cooler temperatures, such as meat and medicine, to avoid seeing stranded loads go bad should a work stoppage occur.

The two rail companies have warned that 9,300 engineers, conductors and yard workers will be locked out at 12:01 a.m. on Thursday unless they can reach new collective agreements, while the union has also said it is poised for a strike.

Both sides remain at the bargaining table after weeks of deadlock over scheduling and wages, with shipments of chlorine for drinking water already halted as part of a phased shutdown poised to progress even further next week.

Federal Labour Minister Steven MacKinnon on Thursday rejected a request from CN to impose binding arbitration as the negotiating clock ticks down.

Industry players, including chemical producers, are growing more alarmed by the day.

害羞草研究所淲e害羞草研究所檙e already in a strike for chlorine,害羞草研究所� said Alan Robinson, commercial vice-president at Chemtrade Logistics Inc. The company says it provides chlorine for 40 per cent of Western Canada害羞草研究所檚 drinking water, as well as much of the western United States.

Its product cannot move by truck or ship, he noted, and safety regulations limit the amount that can be stockpiled.

害羞草研究所淵ou will have boiled water across all Canada and the western U.S.,害羞草研究所� Robinson warned.

The White House and U.S. Environmental Protection Agency both reached out to the Toronto-based company this week with concerns about municipal water treatment, he said.

害羞草研究所淵ou害羞草研究所檙e looking at seven to 10 days once they don害羞草研究所檛 have shipments before they害羞草研究所檙e in trouble,害羞草研究所� said Bob Masterson, CEO at the Chemistry Industry Association of Canada. Most municipalities also have a few more days害羞草研究所� worth of treated water in storage tanks, he added.

Both railways began a detailed process of applying the brakes to freight flows this week.

After Friday, no domestic refrigerated containers will be allowed into CPKC terminals 害羞草研究所� from Vancouver to Saint John, N.B., to Laredo, Texas 害羞草研究所� according to a 害羞草研究所渨ind-down schedule害羞草研究所� obtained by The Canadian Press.

CPKC has also broadened its ban on hazardous materials shipments.

It stopped accepting containers loaded with dangerous goods on Thursday, according to a customer notice.

As of Saturday, the company is rejecting all 害羞草研究所渟ecurity-sensitive害羞草研究所� materials 害羞草研究所� fertilizers and explosives, for example 害羞草研究所� and time-sensitive items, such as perishable food. The embargo expands on a ban on poisonous and toxic inhalation substances from earlier in the week.
