On September 8 — two days ago, as I write this — Canada's newest round of counter-tariffs on American goods came into force: rates of 15%, 25% and 50% on about $27.6 billion worth of U.S. imports, including steel, appliances and electronics. That came three weeks after the U.S. slapped 50% tariffs on a broad range of Canadian products. If you've been half-following the headlines and wondering what any of this actually means for buying, selling or renovating a home in Simcoe County or York Region, this post is my attempt at a straight answer.
Fair warning up front: I'm a realtor, not an economist. What I can do is lay out what's actually in force right now, what the credible research says about costs, and what I'm seeing on the ground in Barrie, Innisfil, Bradford and Newmarket. Where something is a forecast rather than a fact, I'll say so.
Where the tariffs actually stand in September 2026
The trade file has moved so many times that most summaries you'll find online are already out of date. Here's the state of play as of this writing, drawing on the tariff timeline maintained by the law firm Blakes and on Department of Finance announcements:
Steel and aluminum. The U.S. has had 50% tariffs on Canadian steel and aluminum since June 2025, and since April 2026 those apply to the full value of derivative products, not just the metal content. Canada's counter-tariffs on U.S. steel and aluminum products jumped from 25% to 50% on September 8. Canada also put a 25% tariff on a wide range of imported "steel-derivative" products — doors, windows, fasteners, wire — from all countries back in December 2025.
Lumber. Softwood lumber is its own long-running saga, separate from this year's escalation. Canadian softwood entering the U.S. carries anti-dumping and countervailing duties of roughly 35%, plus a 10% national-security tariff. The U.S. Commerce Department has signalled a preliminary cut of the duty portion to about 25%, expected to be finalized around now — a partial easing, not a resolution. Because Canada exports lumber rather than importing much of it, the direct effect here is less about your framing package and more about what it does to Ontario forestry jobs and mill-town economies.
Appliances and finishes. This one lands directly on homeowners. Canada's September 8 counter-tariffs put 25% on U.S.-made appliances and certain steel and aluminum derivative products, and 50% on U.S.-made furniture. If your renovation plan or new-build upgrade sheet leans on American brands, the sticker prices are moving.
The broader picture. The U.S. Supreme Court actually struck down the original "border emergency" tariffs in February 2026, but the sector-specific tariffs on steel, aluminum, autos, copper, lumber and furniture survived, and the U.S. added its new 50% tariffs on $27.6 billion of Canadian goods on August 22 after trade talks broke down. Canada's September 8 order matches those rates dollar for dollar. Negotiations are suspended. Anyone who tells you they know how this ends is guessing.
Do tariffs raise construction costs in Ontario?
Yes — measurably, though less dramatically than the headlines suggest.
Cushman & Wakefield's analysis of Canadian construction estimated earlier this year that tariffs in force were adding about 9.2% to construction materials costs, which works out to roughly a 1% increase in total project cost on average, because materials are only one slice of a build alongside land, labour, financing and development charges. Altus Group's 2026 Canadian Cost Guide points at structural steel and metal components as the biggest drivers of year-over-year cost increases. And the Canadian Construction Association's winter survey found about one in six construction businesses reporting major negative effects from the counter-tariffs — real pain, concentrated in firms that depend on cross-border materials.
For a single detached home, the honest answer is that nobody has a precise Ontario number. South of the border, the National Association of Home Builders has estimated tariffs and duties add several thousand to over ten thousand U.S. dollars to a new American home. The Canadian equivalent depends heavily on what a given builder sources from where — a builder using Canadian lumber, Canadian-made windows and domestic appliances is far less exposed than one specced around U.S. products. That's worth asking about, and I'll come back to it.
One thing pushing the other way locally: development charge relief. Bill 23 reductions and moves like Peel Region's temporary 50% development charge cut have taken meaningful money off the cost of new homes in parts of the GTA. Tariffs and DC relief are pulling builder costs in opposite directions at the same time, which is part of why new-build pricing hasn't simply jumped.
Will tariffs raise home prices in Canada?
This is the question I get at kitchen tables, and the answer most people expect — "tariffs raise costs, so prices go up" — isn't what's actually happening.
Two forces are pulling against each other. Tariffs do push up the cost of building new homes, which over time supports prices by constraining supply — CMHC projects housing starts falling nationally this year, with condo starts dropping sharply in Toronto. But tariffs also weaken the economy: trade uncertainty, softer hiring and cautious households mean fewer buyers competing for homes. CMHC's 2026 outlook expects home prices to decline through 2026 before modest growth returns, precisely because the demand drag is currently winning.
You can see it locally. Barrie is sitting at an average price around the high $600s with roughly six months of inventory — buyer's market territory — and the Barrie & District Association of Realtors described August as a mixed month across Simcoe County. Across York Region the story rhymes: decent selection, patient buyers, sellers who price to the current market selling and sellers who price to 2022 sitting.
So no — tariffs are not sending resale prices up right now. If anything, the economic uncertainty they create is one of the reasons this remains a market that favours prepared buyers. Whether the supply squeeze eventually flips that is a real possibility economists debate, not a fact anyone can promise you.
Buying a new build in Simcoe County or York Region? Ask these questions
New construction is where tariffs touch real estate most directly, and there's a meaningful split in the market right now.
Completed inventory is the sweet spot. A home that's already built was bought at yesterday's material prices, and builders carrying finished inventory in a slow market are negotiating — on price, upgrades, closing credits. That's exactly the situation with the move-in ready homes at Lakehaven in Innisfil, and it's true of standing inventory across the region. The tariff risk on a completed home is essentially zero: the steel is already in the walls.
Pre-construction needs a careful contract read. If you're signing today for a 2028 closing, the questions that matter: Does the purchase agreement have any cost-escalation or price-adjustment clause? What happens to your closing date if materials are delayed? What appliance and finish brands are specced, and can the builder substitute? None of this should scare you off pre-construction — it's how I'd buy it myself in this environment: eyes open, contract reviewed, deposit protected.
Ask where the builder sources. A builder framing with Ontario lumber and installing Canadian-made windows, doors and appliances has genuinely less tariff exposure than one specced around imported product. Good sales offices can answer this; evasive ones tell you something too.
If you're weighing new construction against resale in a specific town, my guides to moving to Barrie, Bradford and Newmarket cover the on-the-ground numbers town by town.
Renovation budgets: where you'll actually feel it
If you're renovating this fall or winter, the tariff line items to watch are specific, not general:
Appliances. U.S.-made appliances now carry a 25% counter-tariff at the border. Retailers absorbed some early rounds of this; with the September escalation, expect more of it to reach the price tag. The workaround is straightforward — Canadian-made and non-U.S. brands aren't subject to the surtax — so it's worth asking your appliance dealer where a given model is actually manufactured before you assume the premium.
Anything steel or aluminum. Railings, garage doors, some windows and doors, fasteners, HVAC components — metal-heavy items have seen the steadiest cost creep, and Canada's own 25% tariff on steel-derivative imports from all countries (in place since December) adds to it.
Cabinets and furniture. U.S. tariffs pushed a lot of cabinet supply chains around in the past year, and Canada's 50% counter-tariff on U.S. furniture will show up in some showrooms.
Practical advice I'm giving clients: get quotes with a defined price-hold window (30 to 60 days), ask contractors to flag which line items are tariff-exposed, and if a major metal or appliance purchase is coming either way, locking it in sooner rather than later removes one variable. If you're prepping a house for sale, my team's renovations and repairs service can help you spend only where it returns.
What tariffs mean for sellers and resale values
Here's the counterintuitive part: tariffs are arguably better for owners of existing homes than for anyone else in the market. Every dollar tariffs add to replacement cost makes your already-built home relatively more attractive — nobody charges a tariff on a house that's been standing since 2005. Over the medium term, fewer housing starts also means less new competition for your listing.
But in the near term, the demand side rules. Buyers in Simcoe County and York Region right now have selection and time, and pricing to the market you're in — not the one from three years ago — is what gets homes sold. Where tariffs genuinely help a seller today is in marketing new-adjacent features: if your home already has the finished basement, the newer windows, the recent kitchen, you're selling work a buyer would now pay tariff-era prices to replicate. That's a real, honest selling point, and we lean on it.
If you're on or near the water, that market runs on its own logic anyway — more on that in my Barrie and Innisfil waterfront guide.
Tariffs and housing: quick answers
Are tariffs making houses more expensive in Canada?
They're making houses more expensive to build — materials costs up roughly 9% by Cushman & Wakefield's estimate — but resale prices are currently flat to falling in much of Ontario because tariff-driven economic uncertainty has cooled demand. Both things are true at once.
Should I wait until the trade war is resolved before buying?
There's no date to wait for — talks are suspended and the situation has already reversed course several times. What you can act on: today's market has inventory, negotiating room and motivated builders. Buy based on your own finances and timeline, not a trade headline. I'm not going to pretend I know where prices go next; neither does anyone else.
Do tariffs affect mortgage rates?
Indirectly. Tariffs push inflation up (bad for rates) but weaken growth (which pushes rates down). The Bank of Canada has been weighing both. If your plans depend on rates, get a pre-approval with a rate hold so the decision is insured either way.
Are new-build prices going up because of tariffs?
Builder costs are up, but soft demand and development-charge relief have kept most new-build pricing in check — many builders are competing on incentives instead. Completed inventory in particular is negotiable right now.
Does any of this change the math on land-lease homes?
The land-lease model itself is untouched — you're still buying the home and leasing the land. If anything, tariff-era build costs make the lower entry price more relevant. My land-lease explainer walks through how the model works and what it costs at Lakehaven.
The bottom line
Tariffs are a real cost pressure on construction and a real drag on confidence, but they are not the housing-market earthquake the headlines imply. Building costs are up single digits, resale prices are soft, buyers have leverage, and sellers who understand the moment are still selling. The right move depends entirely on your situation — which house, which town, buying, selling or renovating.
That conversation is free. Get in touch and I'll give you the tariff-era read on your specific street — whether that's a Lakehaven walkthrough, a pricing strategy for your listing, or a straight answer on whether that pre-construction contract protects you.
