Why U.S. Tariffs Haven’t Yet Impacted Canada’s Window and Door Industry—But Could in the Future

As of March 21, 2025, the Canadian window and door industry, including companies like The Door Centre, has largely avoided the immediate fallout of U.S. tariffs, despite rising trade friction between the two countries. With the U.S. imposing a 25% tariff on most Canadian imports and a 10% rate on energy products, the lack of disruption in this sector might seem surprising. However, several factors explain this stability—and why the future could still bring challenges if trade policies shift.
The tightly knit North American fenestration market is a key protector. Standards aligned by the American Architectural Manufacturers Association (AAMA) and the Canadian Standards Association (CSA), combined with the United States-Mexico-Canada Agreement (CUSMA), allow many products to cross the border tariff-free. At The Door Centre, our doors—made with fiberglass and vinyl frames—along with float glass imports, qualify under CUSMA’s rules of origin. These exemptions keep costs steady for us and our U.S. customers, ensuring that our doors and vinyl windows remain competitive.
Interestingly, the U.S. tariffs on Canadian steel and aluminum, effective March 11, 2025, work in The Door Centre’s favor. Unlike competitors reliant on steel doors and frames, our focus on fiberglass and vinyl frames and windows sidesteps these material cost hikes. While the tariffs target raw metals used in some fenestration products, our inventory and production lean on tariff-exempt materials. This advantage could grow if competitors pass on metal-related products, making our offerings more attractive to our Canadian buyers in the short term.
Yet, this stability isn’t guaranteed. Prolonged tariffs could still strain the broader industry as stockpiles of pre-tariff materials dwindle, potentially raising costs for non-exempt components we might source indirectly. Canada’s retaliatory tariffs—starting with a 25% surtax on $30 billion of U.S. goods on March 4, 2025, and eyeing an additional $125 billion—could also disrupt imports of U.S.-made glass, doors and hardware we rely on. If supply chains snag, we might face higher costs or delays, even though our core fiberglass and vinyl products remain untouched. Reworking supply lines to bypass U.S. dependencies would be costly and could erode our edge but is being investigated.
Looking ahead, our fate ties to trade policy evolution. If CUSMA exemptions persist and negotiations cool tensions, our float glass imports and fiberglass doors should stay unaffected, bolstered by the metal tariffs giving us a pricing edge. But without resolution, rising costs for ancillary materials or supply chain hiccups could pressure us by late 2025. For now, The Door Centre benefits from a unique position—our fiberglass and vinyl focus shields us from metal tariff woes, but we’re not immune to the wider trade storm brewing on the horizon.
