Tariffs and Your Renovation: What Actually Applies in Canada

The tariffs that raise renovation costs in Canada are Canada's own: counter-tariffs on US goods and a 25% tariff on steel derivatives from all countries. US tariffs on Canadian lumber and cabinets apply at the US border, not at your building supply store.

An earlier version of this guide listed US tariffs as costs for Canadian renovators and gave renovation cost estimates without sources. This version covers only the tariffs that apply to purchases in Canada, and uses Statistics Canada figures for prices.

A tariff is paid when goods cross a border into the country that imposes it. So the US tariffs you read about, on Canadian softwood lumber, cabinets or steel, are paid on Canadian exports entering the US. What changes the price of materials you buy in Canada are the tariffs Canada charges on goods coming in.

Canadian tariffs that apply to building materials

Canada's September 8, 2026 counter-tariffs cover 629 US tariff items worth C$27.6 billion a year, matching the US Section 338 tariffs dollar for dollar: 50% on steel, aluminum, furniture and clothing, and 25% on appliances, dairy and some steel and aluminum products (Finance Canada). They apply only to goods made in the US. The steel derivatives tariff applies to listed products from every country, the US included (Prime Minister's Office, November 26, 2025).

What prices have done

Statistics Canada's building construction price index measures what contractors pay to build. For residential buildings across 15 cities, second quarter of 2026 against a year earlier:

These changes have many causes, not only tariffs. Metal work is rising fastest, while wood costs fell slightly. For homeowners, the consumer price index for maintenance and repairs rose 0.9% in the year to August 2026 (Statistics Canada, all causes).

What doesn't raise your costs

• US tariffs on Canadian lumber. Canadian softwood entering the US pays a 10% Section 232 tariff plus anti-dumping and countervailing duties of 35.16% for most companies (Global Affairs Canada). Canadian lumber sold here pays none of this; US-made lumber pays Canada's 25% counter-tariff instead.
• US tariffs on cabinets and furniture. The US charges 25% on imported kitchen cabinets, vanities and upholstered wood furniture, rising on January 1, 2027. That applies to Canadian exports to the US, not to cabinets bought here; US-made kitchen cabinets pay Canada's 25% counter-tariff instead.
• The US Section 232 derivatives list. The US added 407 product codes to its steel and aluminum derivatives list in August 2025. That raises the cost of Canadian exports to the US.

Where you can save

• Ask where it was made. Canada's counter-tariffs apply only to US-made goods on the list; the same product made in Canada or elsewhere doesn't pay them. The steel derivatives tariff is different: it applies to listed products from every country.
• Compare Canadian-made materials. Canadian steel, fasteners, doors and windows pay no import tariff.
• For businesses: Canada's tariff remission framework remains available to assess requests for exceptional relief (Finance Canada, August 25, 2026). Relief for aluminum used in manufacturing, and for steel and aluminum used to make vehicles and aircraft, runs to June 30, 2027.
