Canadian glazing fabricators, window and door manufacturers and installers tracking U.S. trade policy have less than 24 hours before a new 50 per cent tariff takes effect. The order signed by U.S. President Donald Trump on Aug. 19 is set to take effect just after midnight on Wednesday, according to The Canadian Press. The report says the tariffs apply to a variety of goods from cement to hockey sticks, and Canada-U.S. Trade Minister Dominic LeBlanc and chief trade negotiator Janice Charette sat down with U.S. Trade Representative Jamieson Greer and Commerce Secretary Howard Lutnick on Monday.
Prime Minister Mark Carney said Monday he expects to speak with Trump before the Wednesday deadline, adding in French that the federal government has a plan that “will cover all eventualities” if the latest round of tariffs are imposed, according to The Canadian Press. The prime minister also said the negotiations “are very intense and delicate.”
Cost pressure already visible in glazing materials
Even before the new tariff order takes effect, key inputs for Canadian window and door fabricators remain elevated. In its monthly Producer Price Index report, U.S. Glass Magazine reported that aluminum mill shape prices were up 40.5 per cent year-over-year in July, while inputs to new nonresidential construction were up 7.1 per cent from July 2025 to July 2026. The magazine also reported that glass and glass product manufacturing rose 1 per cent in July and sat 5.2 per cent higher than year-ago levels.
For glazing-specific categories, flat glass prices were unchanged in July and were up 3.9 per cent year over year. Metal windows ticked up 0.3 per cent in July and were 15.7 per cent higher than July 2025, while metal doors and frames were flat in July but up 9.5 per cent year over year. Builders’ hardware surged 2.8 per cent in July and was up 4.9 per cent year over year.
“Price relief and additional funding are essential for contractors, project owners, investors and governments,” says Jeffrey D. Shoaf, CEO of Associated General Contractors of America, in the U.S. Glass Magazine article. “Providing lower rates and greater certainty on trade policy while enacting a long-term surface transportation bill would help contractors bid work with greater confidence, invest in their businesses and workforce and ensure critical infrastructure projects continue moving forward.”
FedDev Ontario launches GoEU export program
In a separate announcement, the Federal Economic Development Agency for Southern Ontario (FedDev Ontario) committed $5 million to launch the GoEU program, according to Fenestration Review. The Toronto Business Development Centre (TBDC) will manage the initiative, with FedDev Ontario and the Ontario government each contributing $2.5 million. The program will provide export-readiness assessments, tailored advisory services and direct access to in-market European expertise to Ontario businesses.
Fenestration Review reported that TBDC will prioritize firms looking to diversify exports in response to tariff-related pressures, including those in automotive, steel and related supply chains. The announcement does not single out window, door or glass fabricators, although the “related supply chains” wording leaves room for building product manufacturers that depend on metal components and hardware.
“Southern Ontario businesses have what it takes to compete internationally. By supporting organizations like TBDC, we are helping our companies gain the knowledge, networks, and market access they need to grow in European markets, strengthen their global competitiveness and build trade resiliency to build Canada strong, ” said Evan Solomon, minister of artificial intelligence and digital innovation, in the Fenestration Review article.
Vikram Khurana, chairman of the Toronto Business Development Centre, added, “This is the moment for Canadian entrepreneurs to expand globally. GoEU gives our exporters and tech companies a real running start in Europe, the contacts and the in-market support to acquire customers. With support from the government of Canada and the government of Ontario, we can help these founders not just enter Europe, but grow in it, ” according to Fenestration Review.
What the tariff deadline means for Canadian glazing
The primary tariff order reported by The Canadian Press does not list window, door or glass product categories, instead citing a variety of goods from cement to hockey sticks. That leaves Canadian glazing fabricators to plan around indirect exposure through aluminum, steel, flat glass and builders’ hardware costs, which U.S. Glass Magazine shows are already elevated on a 12-month basis. For Ontario fabricators and installers that serve U.S. customers or rely on cross-border component supply, the combination of tariff uncertainty and rising input prices tightens margins on both sides of the border.
The FedDev Ontario GoEU program targets southern Ontario exporters and aims to help them diversify into Europe, aligning with a Budget 2025 goal to double Canada’s exports outside the United States by 2035, according to Fenestration Review. For glazing manufacturers already working to meet Canadian performance standards such as CSA A440, a shift toward European market qualification could add a parallel set of compliance requirements, even as the program offers in-market support.
Fenestration Review did not specify whether window and door exporters would receive priority under GoEU, but the program’s focus on automotive, steel and related supply chains suggests that fabricators using significant metal inputs may find a path to support. The Canadian Press report notes that Canadian officials remain in Washington as the deadline approaches, with Prime Minister Carney saying the federal government has a plan for “all eventualities,” though no further details were provided before publication.
Until the tariff order’s product list is confirmed and any Canadian response is announced, glazing companies should treat the hours after midnight as a planning window rather than a final outcome, based on the sources available. The situation is fluid, and construction input prices tracked by U.S. Glass Magazine continue to show that tariff-related costs are not limited to a single material or product category.
