ONTARIO — Canadian homebuilders are warning that new US tariffs on steel and aluminium imports could push housing costs even further out of reach as construction expenses rise. With material prices already elevated from inflation and pandemic-driven supply chain disruptions, the industry is bracing for yet another financial strain that could slow new home construction and limit affordability. The Ontario Home Builders’ Association (OHBA), said the tariffs could have serious consequences. OHBA’s Scott Andison said… the tariffs would add pressure to already strained construction costs, making it more expensive to build new homes. That’s a major concern in a housing market where affordability is already a critical issue, particularly for first-time homebuyers. …Some industry leaders fear that if Canada retaliates with its own tariffs, it could make matters worse. Andison said two-way tariffs on cement, gypsum and lumber could push costs “into a crazy level that makes any construction unviable.”
