Canadian Truck Tire Investigation Moves Forward: What Dealers Should Watch

Cover: AI-generated conceptual illustration of the investigation.

Industry update | November 6, 2026

Canada’s investigation into certain truck and bus tires from China has reached a new stage. On October 30, the Canadian International Trade Tribunal (CITT) found a reasonable indication that dumping and subsidizing of the goods under investigation have caused injury to the Canadian industry. The Canada Border Services Agency (CBSA) is continuing separate investigations, with preliminary determinations expected by November 30. CITT announcement.

For commercial tire dealers, the important distinction is between an early injury finding and the decisions still ahead. The October announcement does not itself establish a final duty rate or a final outcome for the case.

What happened

The CITT’s October 30 determination followed a preliminary injury inquiry into certain truck and bus tires from China. It found a reasonable indication of injury to the domestic industry, allowing the investigative process to continue. The CITT is examining injury; the CBSA is separately investigating whether the goods have been dumped or subsidized. CITT announcement; CBSA announcement.

The investigation is about certain truck and bus tires, as defined by the authorities. It should not be read as covering all Chinese tires or all passenger and light-truck tires. Product descriptions, origin and other details matter; consult the official case documents for the precise scope.

What happens next

The CITT says the CBSA will issue preliminary determinations by November 30, 2026. The outcome, any potential duties and their application to individual products remain to be established. CITT announcement.

The Tribunal’s active cases page lists November 16 for the reasons for its preliminary determination. These dates are based on the published schedule and can change; check the authorities’ latest notices rather than treating a calendar date as a final result.

What dealers can do now

A dealer does not need to predict the outcome to prepare a useful conversation with suppliers:

• Identify the products involved. Ask suppliers for the origin, manufacturer and product details needed to compare a specific commercial tire with the official product definition.
• Clarify who imports the goods. Discuss potential customs responsibilities with the importer of record or customs adviser; obligations depend on the transaction and the final official decisions.
• Review quotes and order timing. Ask how a supplier handles potential duty changes, existing orders and price validity. Do not assume prices or inventory will change by a particular amount.
• Set a reminder for the next announcement. Review the CBSA and CITT notices when released and share confirmed information with the team that quotes fleet customers.

These are planning questions, not a declaration that any particular brand, shipment or business is subject to duties. A tire’s country of origin, the product scope and the applicable decision all matter.

The takeaway

The preliminary injury determination is a development for Canada’s commercial tire market, but key findings are still pending. Dealers should keep product and supplier records close at hand and watch the CBSA’s next announcement before drawing conclusions about landed costs or prices.
