The CBSA launches investigations into the alleged dumping and subsidizing of truck and bus tires from China

On August 31, 2026, the Canada Border Services Agency (CBSA) initiated investigations to determine whether truck and bus tires are being sold at unfair prices in Canada (dumped), subsidized, or both. The investigations focus on imports from producers operating in or exporting from China. These practices can harm Canadian industries by undercutting prices, which undermines fair competition.

The CBSA’s investigations follow a complaint filed by the Canadian Retread Manufacturers Association (CRMA) and Michelin North America (Canada) Inc. (Michelin), the complainants in this case. The complainants allege that as a result of an increase in the volume of the dumped and subsidized imports, they have suffered material injury in the form of price undercutting, price suppression, lost sales, lost volumes and market share, reduction in capacity utilization, reduced employment, reduced profitability, and negative impact on investments.

The CBSA and the Canadian International Trade Tribunal (CITT) both play a role in the investigations. The CITT will begin a preliminary inquiry to determine whether the imports are harming Canadian producers and will issue a decision by October 30, 2026. Concurrently, the CBSA will investigate whether the imports are being sold in Canada at unfair prices, subsidized, or both, and will make preliminary decisions by November 30, 2026.

The Special Import Measures Act (SIMA) protects Canadian producers and jobs from unfair trade, thereby safeguarding Canada's economy. In 2025, SIMA duties applied to approximately $3.3 billion worth of imports in industries employing 43,728 people in Canada. Currently, there are 187 special import measures in force in Canada.
