The union representing dockworkers at the Port of Montreal has concluded a three-day strike at two of the port’s major terminals, but the potential for further disruptions and supply chain challenges looms as tensions remain unresolved.
The Maritime Employers Association confirmed that operations resumed at 7 a.m. on Thursday, October 3, at both the Viau and Maisonneuve terminals. These terminals handle over 40% of the container traffic at Canada’s second-largest port, making the strike’s impact significant for businesses reliant on timely imports and exports.
Despite the end of this particular work stoppage, negotiations between the union and management have stalled. The two sides did not meet last week, with the union criticizing management for refusing to participate in a meeting arranged by federal mediators.
Michel Murray, a spokesperson for the union local affiliated with the Canadian Union of Public Employees, expressed frustration with the employers’ approach: “What is this employer up to? It denounces the effect of a partial strike on the economy and on the supply chain, but it doesn’t deign to come to the negotiating table to find solutions.”

The Maritime Employers Association, which represents shipping companies and terminal operators, stated that no meeting had been planned. They emphasized their commitment to reaching a collective agreement through continued negotiations. The Federal Mediation and Conciliation Service confirmed that mediators are still in contact with both parties, though no further details were provided on the status of the discussions.
Over the summer, the union delayed its response to a contract offer submitted by the employers for two months, according to Isabelle Pelletier, a spokesperson for the employers association. “Clearly, the current mediation process is no longer producing results,” she said. “We are evaluating all options available to achieve a sustainable solution that reflects the current situation.”
The recent strike involved a quarter of the port’s 1,200 workers, starting on Monday, October 1. Coinciding with this, tens of thousands of dockworkers in the United States initiated a work stoppage at 36 U.S. ports, effectively halting around half of the country’s ocean cargo. The combined strikes have raised concerns among Canadian businesses dependent on the movement of goods between the two countries.
Products destined for Canadian warehouses and retailers often pass through U.S. ports, while some Canadian exports are routed to U.S. ports before being shipped abroad. The impact of these labor disruptions could be particularly severe if strikes persist in either country.
Manufacturers are similarly concerned about the potential for supply chain disruptions. Many operate on tight schedules with just-in-time inventory practices, leaving little room for delays.
Machinery, mechanical appliances, and transportation equipment made up over 39% of U.S. exports to Canada in 2021, according to the U.S. Office of Technology Evaluation. The Port of Montreal handles about $50 million worth of manufactured goods or components daily, meaning further strike action could lead to significant backlogs.
The dockworkers union must provide a 72-hour notice before initiating another strike. The strike mandate approved by members on September 25 remains in effect for 60 days, leaving the possibility of additional job action in the weeks to come.
