Carpet Tariffs Are Quietly Driving Up Housing Costs in Canada
A three-bedroom townhouse in Brampton sat unfinished for six weeks this summer because the builder couldn't close the carpet order without breaking the budget. The flooring was supposed to cost $11,400. Anti-dumping duties pushed it to $14,200. The delay cost more than the tariff.
That scenario is playing out across Canada's residential construction sector, where protective tariffs on U.S. carpet imports are adding unexpected costs to the exact housing segment policymakers say they want to encourage. While luxury detached homes use hardwood, the affordable housing and rental sectors rely heavily on carpet. Multi-unit developments, townhome complexes, and rental buildings buy it in volume. A tariff that looks modest on paper, double-digit percentages in recent cycles, compounds fast when a builder is carpeting 80 units at once.
The Canada Border Services Agency and the Canadian International Trade Tribunal oversee these duties, which kick in when foreign suppliers are suspected of dumping product below cost. The mechanism exists to protect Canadian manufacturers. The problem is timing. Builders who signed contracts in 2024, before the latest round of duties landed, are hitting the completion phase in 2026 and discovering that the soft-surface budget no longer works. They can't renegotiate supplier contracts mid-build, and they can't absorb a 20% cost spike on a line item that was already thin.
The Wrong Part of the Supply Chain
Under the Canada-United States-Mexico Agreement, most goods move duty-free. But Rules of Origin disputes create exceptions, and synthetic fiber carpets are one of them. When the CBSA determines that a U.S. exporter sold below fair value, the tariff arrives as a surprise mid-project expense. It's the construction equivalent of a rate hike that only hits one material category.
The irony is sharp. Ottawa's target is 3.87 million new homes by 2031, a figure the CMHC set to restore affordability. The missing middle, townhomes, stacked condos, purpose-built rentals, is where that volume has to come from. Those are the projects where carpet is a high-volume cost. A protective tariff designed to save domestic manufacturing jobs is functioning as a tax on the housing stock the federal government says it wants built.
Developers are responding by moving toward tariff-resilient procurement. Some are switching to Canadian manufacturers, though domestic capacity is limited and lead times are longer. Others are sourcing from overseas suppliers outside the CUSMA framework, adding shipping complexity. A third group is simply eating the cost and reducing the total number of units they'll build in the next cycle.
The Completion Trap
The worst cases are builders who locked financing in 2024, when the Bank of Canada's overnight rate sat above 4.5%, and are now finishing projects in a lower-rate environment. They paid higher construction loan interest for two years. The tariff arrives just as they're trying to close sales and recover. The arithmetic stops working when one material category jumps 20% after the marketing started.
Variable mortgage rates in September 2026 sit near 3.3%, and high-ratio five-year fixed insured terms are around 3.9% to 4.2%. Buyers are returning. But pent-up demand is for completed units: occupied townhomes and rental buildings ready for tenants, not projects frozen mid-construction because a carpet order broke the budget.
Protective tariffs serve a purpose. Canadian flooring manufacturers shouldn't have to compete with predatory pricing. But the mechanism needs to account for the lag between contract and completion. A builder signing deals today is managing risk for 2028. A tariff that appears mid-build doesn't protect jobs. It just moves the pain.
