A three-day strike by unionized Montreal port workers that shut down two container traffic terminals ended early on Thursday as scheduled, the port authority said in a statement.

The union representing Montreal dockworkers has ended a three-day strike at two terminals as scheduled, but the potential remains for more job action and jammed supply chains in the coming weeks.

Last Friday, the Syndicat des débardeurs du port de Montréal filed a 72-hour strike notice, saying its members who work at the Viau and Maisonneuve terminals intended to walk out from 7 a.m. Monday to 6:59 a.m. Thursday.

Unionized workers have begun a three-day strike at two terminals of the port of Montreal as talks over a new contract are yet to result in a labor agreement, the Canadian port's authorities said on Monday.
