US-Canada Tariffs and Ontario Real Estate: What Buyers and Sellers Need to Know in 2026

The US-Canada trade dispute has been a slow-moving story in the background — until it started showing up in home prices. If you're buying, selling, or building in Ontario in 2026, the tariff situation is now directly relevant to your budget and your timeline. Here's what's actually happening, and what it means for you.

The Tariff Situation in Plain English

The United States imposed broad tariffs on Canadian imports beginning in early 2025, including a 25% tariff on Canadian steel and aluminum, and escalating duties on softwood lumber that now sit at approximately 34%. Canada responded with retaliatory tariffs on a range of US consumer goods.

For most Canadians, this played out as higher prices at the grocery store and for imported appliances. But in real estate, the impact runs deeper — because homes are built from the very materials being tariffed.

How Tariffs Are Hitting New Construction

Ontario builders source a significant portion of their lumber, steel framing, and engineered wood products from supply chains that are now disrupted or repriced. Even where materials are sourced domestically, global pricing has been pulled upward by the trade war.

The Canadian Home Builders' Association estimated in Q1 2026 that tariff-related cost increases are adding between $15,000 and $40,000 to the cost of a new detached home, depending on size and finishes. For townhomes and condos, the number is lower but still meaningful.

The Resale Market: Indirect but Real Effects

On the resale side, the tariff impact is less direct but still real:

• Renovation costs are up. Anyone renovating to sell — or buying a home that needs work — is paying more for lumber, fixtures, windows, and appliances. A kitchen reno that cost $45,000 in 2024 may run $55,000+ today.
• Buyer confidence has softened. Economic uncertainty from the trade war has made some buyers more cautious about committing to a purchase, contributing to slower spring activity in certain GTA pockets.
• Sellers are reluctant to list. Homeowners who might sell and move up are hesitating because they know the cost to renovate or build new has risen. This keeps resale inventory lower than it might otherwise be.

Winners and Losers in This Environment

Will Prices Rise Because of Tariffs?

The honest answer: in the new construction segment, yes — prices are already reflecting tariff costs. In the resale market, the picture is more complex. The tariffs are one input among many, and right now they're being partially offset by:

• A stable Bank of Canada rate (2.25% as of May 2026) keeping borrowing costs predictable
• Slightly elevated resale inventory compared to 2021–2022 peaks
• Reduced buyer purchasing power after two years of rate increases

The net effect is not a tariff-driven price spike in resale — but it does put a floor under prices in areas where new construction is the main alternative. If you're choosing between buying resale and waiting for new supply, the cost advantage of resale is now larger than it has been in years.

What About Appliances, Fixtures, and Finishes?

Many home appliances — dishwashers, refrigerators, laundry units — are manufactured in the US or contain US-sourced components now subject to Canadian retaliatory tariffs. Expect to pay 10–20% more for major appliances than you would have two years ago. This affects:

• Buyers negotiating for appliances to be included in the sale
• Sellers doing pre-listing upgrades to maximize sale price
• New construction buyers choosing builder upgrade packages
