Canadian tariffs and your business.
A practical guide for construction and trades owners
Tariffs can squeeze margins on work you’ve already sold and create opportunities for what comes next.
Understand where your business is exposed, which products are affected, what financial support may be available and what to do now.
Tariffs and your business
A working resource page for Canadian construction and trades owners.
Tariffs are not necessarily good news or bad news for a Canadian business. Surprisingly, for many owners, they are both. You may have margin at risk on work you have already sold, while seeing opportunities to strengthen Canadian supply relationships, add capacity or enter new markets.
The bigger questions are:
- Where am I exposed?
- Where is there opportunity?
- What do I need to do about it now?
On September 8, covered U.S.-origin steel your American competitor sells into Canada starts facing a 50 per cent tariff at the border. Depending on what you build and who you buy from, that is either the best competitive news you have had in years or a cost problem that lands in the middle of a signed contract. For most of you it will be both at once.
At 12:01 a.m. on September 8, 2026, Canada’s counter-tariffs took effect on specified American goods covering $27.6 billion. The rates are 15, 25 and 50 per cent, matched product by product against what the United States charges Canada.
Resist the urge to summarise that as “steel is 50 per cent.” Rates vary sharply inside categories, and the variation is not intuitive. Listed steel radiators are 25. Wooden kitchen cabinets are 25 while wooden bedroom furniture is 50. Specified air conditioners are 15, air conditioning machines without a refrigerating unit are 25, household refrigerators are 25, and refrigerated display cases are 50. Which tariff item the goods on your purchase order fall under matters more than which industry you are in.
Most of the coverage this week picked one story and ran with it. Either this was a win for Canadian manufacturing or it was a disaster for anyone who imports. Both versions are true, and which one applies to you has nothing to do with your industry and everything to do with where you sit in the transaction.
So we pulled out the part that matters to construction and trades. What is changing, which tariff items touch your business, what the federal money is for, and what to decide now.
01
What’s Changed
The short version is that Canada matched the American action dollar for dollar and rate for rate. The longer version matters more, because the details determine whether a specific shipment is caught.
- Effective
- 12:01 a.m., September 8, 2026
- Scope
- Specified tariff items, covering $27.6 billion in imports from the U.S.
- Rates
- 15, 25 and 50 per cent, matched product by product to the corresponding U.S. rate
- Biggest move
- Specified steel and aluminum products previously at 25 per cent moved to 50 per cent. Certain derivative products remain at 25 per cent.
- Origin rule
- Applies only to goods that qualify to be marked as a good of the U.S.
- In transit
- Qualifying goods already in transit to Canada when the measures took effect are not caught; retain shipping evidence
- Still in place
- Existing counter-tariffs, including autos. The remission framework remains open for exceptional relief.
Two of those points are worth reading twice. The origin rule means a product that ships from an American distributor is not automatically caught. What matters is whether the good itself qualifies to be marked as a good of the U.S. And the in-transit exemption means qualifying goods already bound for Canada and under a carrier’s control when the measures took effect are not subject to these new counter-tariffs. Arrival date alone does not settle it. Keep shipping evidence such as a bill of lading. A purchase order date alone does not establish the exclusion.

The American side of it
This is a response, not an opening move. The United States imposed 50 per cent tariffs on $27.6 billion of Canadian goods effective August 22. Canada suspended negotiations rather than accept the terms on the table, then matched the action.
If a meaningful share of your revenue crosses the border southbound, Canada’s counter-tariffs do not solve that problem. Your market got more expensive to serve and nothing in the counter-tariff list changes that. The diversification programs further down this page are the part to explore.

02
Which side of the trade are you on?
This is the question that determines everything else on this page, and it is the one that most of the coverage skipped. Work out which of these describes you before you read another word about tariffs.
Advantage: you sell into Canada and buy Canadian
From September 8, covered U.S.-origin goods land in your home market carrying tariffs of up to 50 per cent on customs value. How much of that reaches a competitor’s quoted price depends on how their Canadian sales are structured, but direct tariff exposure may sit in their supply chain rather than yours if you are sourcing Canadian; Canadian suppliers may still face imported-input costs. The question is whether you have the capacity and the people to take the share that opens up, and eligible federal support may help.
Cost exposure: you buy American steel, aluminum, appliances or millwork
Your cost exposure changed on September 8. Fixed-price work in backlog that was priced before the announcement puts that margin at risk if covered inputs now cost more and you have no way to pass through or avoid the increase.
Export pressure: you export building materials south
The new American tariffs on specified Canadian goods took effect August 22. Nothing in Canada’s response fixes that. The diversification funding matters more to you than the counter-tariff list does.
Most likely you: two sides at once
A mechanical contractor buying American aluminum while competing against American fabricators is both an input buyer and a domestic seller. So is a structural steel shop. Do not let anyone sell you a strategy built on only half of it.
The companies that will handle this badly are the ones that read only the half of the story that matches their mood. If you are feeling optimistic you will notice the market opening and miss the backlog exposure. If you are feeling defensive you will reprice everything and miss the fact that your competition just picked up a new cost you may not have.
03
What actually got more expensive
The federal list covers a wide range of tariff items. We pulled out the ones that touch a construction or trades business and grouped them by who buys them rather than by tariff chapter, because nobody looks up ductwork under chapter 73.
The single most useful thing on this page is that the rates are not uniform inside a category. A contractor who reads “steel is 50 per cent” and assumes their whole steel spend is affected at that rate is going to reprice the wrong things.
The selected construction and trades items are listed below.
Where a four-digit heading is shown, every item published under that heading on the federal schedule carries the stated rate. Where a heading contains more than one rate, the specific subheadings are listed separately. Only the items listed in the federal schedule are covered; a heading reference does not establish coverage of every product within it.
04
The federal money, and what it is actually for
The government attached a $7.5 billion package to this announcement, on top of roughly $25 billion already deployed since the tariffs started. It is worth understanding how this package is shaped, because it is not built like the last round of federal business support.
The pandemic-era supports were heavily weighted toward wage and rent subsidies and emergency liquidity: helping companies protect payroll, cover fixed costs and survive a sudden revenue shock. This package is doing two different jobs at once, and it is worth separating them before you read the list.
Part of it is defence. The $500 million BDC liquidity stream, the liquidity support inside the regional agency money, the EI flexibilities and the worker retention side of the Rapid Response funding are all there to help a business absorb a hit and hold on to its people.
Part of it is offence. The $2 billion for diversification and capital maintenance, and the workplace training and retraining money, can support companies adding capacity as well as maintaining it.
Which half you reach for depends on which side of the trade you landed on in section 02. A company exposed on both sides may fit more than one program. Check eligibility and funding-stacking rules before assuming the supports can be combined.
Amounts below are federal program allocations or additions, not individual awards. Eligibility and funding-stacking rules apply.
TO MAINTAIN OR ADD CAPACITY $2 billion
Canada Strong Diversification Fund
Effective immediately as a new stream of the Strategic Response Fund. Supports tariff-affected companies, including medium-sized firms, with shovel-ready capital-maintenance projects. Finance Canada says regional development agencies will support project intake and triage. Check the official program page for eligibility and application requirements.
Official sources: Program information
TO RETAIN OR RETRAIN PEOPLE $3.5 billion
Rapid Response Supports for Workers and Employers
Rapid-response support includes EI flexibilities, workplace training and a proposed program combining Work-Sharing and the Worker Retention Grant, with up to $1,000 per participant for training and administration. The combined program is listed as coming soon. Existing Work-Sharing and Worker Retention Grant support is available to eligible employers; check the application requirements.

TO FUND THE GAP $500 million
BDC Pivot to Grow
A new liquidity stream for immediate cash-flow pressure, alongside targeted programs for forestry, steel and aluminum. The announced expansion lowers the minimum revenue requirement for BDC tariff programs to $1 million. Other eligibility and lending conditions apply.
Official sources: BDC program information
REGIONAL $1.5 billion additional
Regional Tariff Response Initiative
PrairiesCan delivers this funding in the Prairie provinces. The August 25 expansion adds funding and liquidity support for tariff-affected businesses. Confirm eligibility, the application process and intake dates with your regional development agency; requirements differ by region.

LARGE ENTERPRISE New flexibilities
Large Enterprise Tariff Loan facility
Administered by the Canada Enterprise Emergency Funding Corporation. Most companies reading this page will not qualify. It is listed so you can rule it out and stop reading about it.
Official sources: LETL information
EXCEPTIONAL CASES Still open
Tariff remission framework
Remains available to assess requests for exceptional relief. This is a narrow door, not a general exemption. Worth a conversation with your customs broker before you invest time in an application.
Official sources: Remission request process
If the business needs to get smaller
Some businesses may need to downsize. Start with what your backlog and cash flow can support, then explore the financial resources above with your accountant, lender and regional development agency. Eligible liquidity support may help you adjust; if the slowdown is temporary, Work-Sharing may help retain people on reduced hours. Check the conditions and build the plan around confirmed funding.
The practical problem with programs like these is timing. Intake details can move quickly, eligibility takes time to sort out, and waiting until a program is widely understood can mean starting the process later than you needed to. If any of the entries above describe something you were already planning for the next eighteen months, or you need help managing a slowdown, move the conversation forward now rather than waiting for perfect information.

05
What to decide in the next 30 days
Five things. None of them should wait.
-
Reprice your backlog on paper
Not your pipeline. Your signed, fixed-price, not-yet-delivered work. Work out which inputs are covered U.S.-origin goods under a listed tariff item, then which of those were not already in transit on September 8. Those are your exposure. For direct imports, apply the surtax to value for duty; for purchases through a supplier, confirm the actual price increase. Run those costs through the job so you know the real number instead of the number you are hoping for. Do this before the conversation with your bank, not after.
-
Read your escalation clauses this week
Find out whether you have them, whether a tariff change specifically triggers them, and what notice period they require. Notice periods are the part people miss. A clause you cannot trigger in time may not protect you.
-
Get Canadian supplier quotes now
Every competitor you have is about to have this same idea. Supply gets tight and lead times stretch when demand shifts this fast. Being early here is worth considerably more than being clever.
-
Decide whether to grow, hold steady or downsize
If covered U.S.-origin goods competing in your market are carrying tariffs of up to 50 per cent, that may create openings through higher pricing, tighter margins or competitors walking away from work. The constraints on taking that share are capacity, people and cash flow; eligible federal support may help. There may also be reasons to hold steady or downsize. Explore the financial resources above before deciding what the business can support. This is a decision, not a drift. Make it deliberately and tell your team which direction you picked.
-
Sort out which pool you fit before you apply
Eligibility is specific and the intake processes differ by program. A short conversation with your accountant and your regional development agency will save you more time than a week of reading program pages on your own.
06
What we are telling clients
We work with owner-led construction and trades companies every week, and the same two questions have come up in almost every conversation since the announcement.
“Don't just ask what the tariffs are going to cost you. Ask what they could change for your business. Maybe it's a chance to add capacity, strengthen your Canadian supply chain, enter a new market or pick up customers you couldn't compete for before. The opportunity will be different for every business. The important thing is recognizing yours and being ready to act on it.”
“The first place I'd look isn't your pipeline...it's your backlog. What have you already committed to at a fixed price, what inputs are exposed, and where could your margin disappear before anyone notices? Before you worry about what's coming next, understand the risk that's already sitting in the business.”
If tariffs change your margin, they may change what a buyer sees
A good buyer will not simply mark you down for a compressed year. They will ask harder questions than that. Is the compression temporary or structural. Can it be normalized, and will the adjustment survive scrutiny. Has your pricing caught up. Is the supplier exposure still sitting there, or have you moved it.
Those are answerable questions. The answers are worth considerably more if you have worked them out in advance rather than during diligence, and they are worth more still if you can show what you did about it.

Construction and trades tariff items
Pulled from the federal schedule and grouped by who buys them rather than by tariff chapter. Selected construction and trades items from the counter-tariff list effective September 8, 2026.
These are indicative descriptions, not classification advice. Use the middle column as a reference and have your customs broker confirm the full eight-digit tariff item. The construction cut was checked against Finance Canada’s item-level counter-tariff list; mixed headings are broken out rather than treated as fully covered. Confirm the classification and current rate before acting. The rates shown are surtaxes under this measure; other duties or relief may apply.
