On October 30, 2026, the Canadian International Trade Tribunal (CITT) issued a determination in its preliminary injury inquiry PI-2026-005: there is a reasonable indication that the dumping and subsidizing of certain truck and bus tires from China have caused injury to the domestic industry. The Canada Border Services Agency (CBSA) will continue its investigations and is expected to issue preliminary determinations by November 30, 2026.
What this means in plain English
Dumping means the tires are sold in Canada at prices lower than their home-market value. Subsidizing means Chinese producers benefit from government subsidies. The CITT’s job at this preliminary stage is only to decide whether there is a reasonable indication of injury to Canadian producers. That bar is low by design. The finding means the case proceeds.
Why contractors and renovation businesses should pay attention
If you run work trucks, dump trailers, flatbeds, or any fleet in the renovation and exterior trades, tires are a real line item. If provisional anti-dumping and countervailing duties land after the CBSA’s November 30 preliminary determinations, cheap Chinese truck and bus tires could get dramatically more expensive at the border, sometimes with duties exceeding 100 percent in these cases. Two practical effects:
- Budget tires you have been buying may jump in price or vanish from distributors.
- Domestic and non-Chinese brands may become relatively more competitive, and stock levels could shift quickly as importers adjust.
What happens next in the process
- CBSA preliminary determinations: due by November 30, 2026. If affirmative, provisional duties are applied immediately.
- Final injury inquiry: the CITT will later hold a full inquiry and issue a final determination, typically within about 60 days of the CBSA’s final decisions.
- If the final finding is affirmative, anti-dumping and countervailing duties can stay in place for five years.
Practical advice for fleet buyers
If you know you will need tires for the 2027 season, watch the CBSA announcement at the end of November. Importers often front-load stock ahead of preliminary duties, so availability can tighten fast. Do not count on grey-market pricing holding.
Bottom line
This is a genuine cost-of-doing-business story for anyone in the trades running trucks. Track the November 30 CBSA preliminary determination before you set 2027 fleet budgets.
