The brewing tension between Canada and the US has escalated into a full‑blown trade war, disrupting cross‑border supply chains, driving up the cost of construction materials, and threatening to throw the timelines of major housing projects into disarray. …Developers already grappling with labour shortages, high interest rates, and soaring land costs, now face a destabilizing force that could impact every aspect of the construction process. …“The construction industry continues to build through uncertainty, but contractors are facing increasing pressures in getting the job done,” said Rodrigue Gilbert, President of the Canadian Construction Association. …Meanwhile, the US housing market is feeling the shock as well. …The long‑term implications of the trade war reach far beyond construction sites and border checkpoints, according to a report by the Canadian American Business Council by Oxford Economics. The analysis underscores the depth of Canada–US economic integration and how mutually beneficial that relationship has been for decades.
