About 180 grainhandlers at three Thunder Bay terminals operated by Viterra, Richardson and Superior Elevator issued a 72-hour strike notice after rejecting the companies' final offer. The United Steelworkers union said it is seeking a return to talks with help from a federal mediator.
Key disputes involve cost-of-living issues and pensions, and the previous contract expired Feb. 1.
Thunder Bay is a major Canadian grain export port, so a walkout would delay canola, wheat and other oilseed shipments and could widen Canadian basis and export spreads. Supportive for prices of Canadian meal and grain if the strike proceeds.
