The CBSA launches investigations into the alleged dumping and subsidizing of unarmoured building cables from China

The complaint is supported by domestic producers in Canada, including: Domtech Inc. (Trenton, Ontario), Nexans Canada Inc. (Thornhill, Ontario) and Northern Cables Inc. (Brockville, Ontario).

Ottawa – The Canada Border Services Agency (CBSA) announced today that it is initiating investigations to determine whether unarmoured building cables are being sold at unfair prices in Canada (dumping) and/or are being subsidized. 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 PTI Cables Inc. (the complainant). The complainant alleges 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 depression, lost sales, as well as adverse impacts on production, capacity utilization, market share, employment and financial performance.

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 the Canadian producers and will issue a decision by May 15, 2026. Concurrently, the CBSA will investigate whether the imports are being sold in Canada at unfair prices and/or are being subsidized, and will make a preliminary decision by June 15, 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 181 special import measures in force in Canada.

Unarmoured building cables are used to distribute electricity within or in relation to a residential, commercial or other structures for the purpose of providing power to light fixtures, appliances, heating and cooling apparatuses, electrical sockets and other equipment.

The complainant, PTI Cables Inc., is a producer of unarmoured building cables located in Pointe-Claire, Quebec.

The complaint is supported by domestic producers in Canada, including: Domtech Inc. (Trenton, Ontario), Nexans Canada Inc. (Thornhill, Ontario) and Northern Cables Inc. (Brockville, Ontario).

Based on the information included in the complaint, the complainant and supporting producers represent the majority of Canadian production of unarmoured building cables.
