Maersk Warns Canadian Importers to Brace for Peak-Season Disruptions, Tariff Changes

Canadian importers and exporters should expect continued supply chain turbulence heading into peak season, with new tariff measures, port congestion and inland transport bottlenecks adding cost and complexity, according to Maersk’s latest North America market update.

The global shipping giant said low water levels on the St. Lawrence River are limiting vessel capacity into Canada, complicating planning for businesses already navigating variable lead times and shifting trade flows. On the East Coast, congestion around Montreal is being compounded by major road construction at Turcot, Ville Marie and the La Fontaine Tunnel, while high dwell times in Newark are slowing Canada-bound rail cargo.

Reefer trucking into Canada is especially tight. Maersk urged shippers to book refrigerated equipment earlier than usual and build up safety stock to buffer against late arrivals. The company also recommended flexible Montreal delivery windows and considering alternative inland ramps or gateways to avoid bottlenecks.

“Plan Canada moves with added lead time and keep Montreal delivery windows flexible to account for variable discharge and roadworks,” the company said in its update.
