Last week, Canada issued a one-year extension of rules aimed at speeding grain movement by rail. The rules were put in place after a massive backup of grain occurred in Canada’s Western Prairies in 2014. Pro Farmer’s First Thing Today reports the rules give U.S. railways more access to Canadian shipments and require the two main Canadian railways, Canadian National Railway and Canadian Pacific Railway, to ship a minimum amount of grain. The minimum grain shipment requirements have since been lifted, but the extension continues the government's authority to enact them again, if needed. The rules will now be in place through August first of next year.
