The Montreal Longshoremen’s Union rejected a final offer made for a new labour contract, leading to a lockout being declared, the Maritime Employers Association (MEA) and the union said on Sunday. The MEA said the lockout will impact nearly 1,200 port workers at the Canadian port that handled 8.7 million metric tons in the third quarter of 2024. The lockout will further slow Canadian imports and exports at a time the Port of Montreal was already operating at partial capacity and as West Coast ports are stopped due to a separate dispute. The union representing longshoremen at the Port of Montreal said the offer was rejected by 99.7% of members because the employer refused to negotiate. Two terminals operated by Termont, representing about 40% of Montreal’s container traffic and 15% of total port volume, have been shut down since Oct. 31. However, after Sunday’s announcement all longshoring at the port will be locked out.
