Canada’s trucking industry is entering a more complicated phase of the trade fight with the United States. New U.S. tariffs took effect on August 22, targeting billions of dollars in Canadian goods, while Ottawa is preparing matching counter-tariffs for September 8. For trucking companies, the problem reaches far beyond what happens at customs booths.
Freight patterns were already becoming less predictable before the latest measures arrived. Domestic Canadian loads have been taking a larger share of the spot market, cross-border growth has become increasingly uneven, and carriers are confronting the possibility that fewer export loads could leave trucks in the wrong places. The result is not yet a nationwide freight collapse. It is a growing operational squeeze in which losing one profitable cross-border movement can make an entire round trip—and sometimes the Canadian leg attached to it—harder to justify.
The Border Market Was Already Changing Direction
Canada’s freight market entered the latest tariff escalation with surprisingly strong year-over-year numbers, but weaker month-to-month momentum. Loadlink Technologies reported that total Canadian freight postings in July were 41% higher than a year earlier, yet volumes declined 7% from June. Cross-border freight represented 58% of postings from Canadian-based customers, while domestic freight increased its share. That combination matters because it suggests carriers were already adjusting where they found work before the new U.S. tariffs took effect.
The directional numbers were even more revealing. U.S.-to-Canada loads dropped 27% from June, although they remained 46% higher than July 2025. Canada-to-U.S. loads increased 16% month over month and 35% year over year, but Loadlink said annual outbound growth had been cooling steadily since its April peak. In other words, cross-border trucking was not disappearing in July. Instead, the market was becoming more uneven, with inbound and outbound freight moving differently and domestic routes claiming a larger portion of available activity.
The New Tariffs Target Freight-Heavy Parts of the Economy
That fragile balance now faces a much bigger test. The United States imposed a 50% tariff on approximately C$27.6 billion of Canadian goods effective August 22. Canada has announced that it will respond with additional tariffs of 15%, 25% and 50% on C$27.6 billion of U.S. imports beginning September 8. The Canadian response covers sectors including steel and aluminum, dairy, appliances, agricultural equipment, pulp and paper, plastics and electronics.
Those categories matter enormously to trucking because they generate recurring industrial, agricultural and retail freight rather than isolated consumer shipments. A factory producing metal components may require inbound raw materials, outbound finished products and movements between suppliers before anything ever reaches a border. Agricultural equipment and appliances similarly feed distribution centres, dealers and regional warehouses. When tariffs cause buyers to postpone orders, substitute suppliers or rethink production, the trucking impact can multiply across several movements. A tariff may technically apply to one shipment crossing the border, but the lost freight can affect Canadian pickup lanes, warehouse transfers and regional delivery work linked to the same supply chain.
One Lost Southbound Load Can Disrupt the Trip Back
The Canadian Trucking Alliance has warned that weaker exports can create problems in both directions. Canadian fleets frequently build cross-border operations around a sequence of movements rather than treating every trip independently. A truck that delivers Canadian freight into the United States can then pick up another load for the return journey. If the southbound shipment disappears, the equipment may never be positioned in the United States to handle the northbound load.
That is why the industry is increasingly focused on equipment imbalance rather than simply counting fewer exports. The Canada Truck Operators Association has highlighted the costs smaller fleets and owner-operators can face when tariff-sensitive shipments are cancelled, rejected or delayed. Drivers still need to be paid, f
