The Trade War and Your Mortgage: What Actually Reaches Your File

The question we actually get asked

A version of this reaches us most weeks: there is a tariff fight on, the economy is going to take a hit, so should we sit in a variable term and wait for the cuts? For most of the past two years that reasoning held together. Weakness stories are borrower-friendly — the Bank of Canada eases, the qualifying figure softens, pricing follows. As of this month the machinery is pointing somewhere else.

On 2 September 2026 the Bank of Canada left its policy setting at 2.25%. Its announcement said the continuing conflict in the Middle East is keeping energy prices high, and that new US tariffs and Canadian counter-measures have been announced following the breakdown of trade talks. With the economy and inflation evolving broadly as forecast in the July Monetary Policy Report, Governing Council agreed to leave the setting unchanged — but the framing of the risks moved.

The upside risks to inflation have increased, while new tariffs make growth prospects more uncertain.— Bank of Canada, policy announcement, 2 September 2026

This piece was prompted by RBC Economics' 27 August note on the trade war, which is a careful read of the tariff facts. It was also written six days before that announcement, and it described recent inflation readings as lower. Statistics Canada's July release, published 17 August, shows headline CPI at 3.0% year over year after 2.8% in June. When a bank's directional call and the central bank's own sentence disagree, we take the central bank's sentence.

What actually changed, in three paragraphs

Finance Canada's 25 August release states that following the US decision to impose a 50 per cent tariff on $27.6 billion of Canadian goods effective 22 August, Canada will match the new US measures dollar for dollar and tier for tier. The Canadian counter-tariffs take effect 8 September and cover $27.6 billion in imports from the United States.

The counter-tariff schedule Finance Canada published sets three tiers — 15, 25 and 50 per cent — with each product matched to the equivalent US measure on the same goods. The 50 per cent tier includes steel and aluminum products previously carrying only a 25 per cent counter-tariff, along with furniture and clothing and apparel. The broader list runs across steel, dairy, appliances, agricultural equipment, pulp and paper, and electronics.

On the same day, Ottawa announced a $7.5 billion package of new and enhanced measures for workers and businesses, building on nearly $25 billion in supports over the previous 18 months. It bolsters the Regional Tariff Response Initiative delivered by the seven Regional Development Agencies by $1.5 billion, consolidates the EI Work-Sharing program and the Worker Retention Grant into a single Workforce Retention and Retraining Program, and extends EI measures so laid-off or separated employees can access benefits sooner and alongside severance.

Why a cost shock pushes the wrong way for borrowers

A demand shock and a cost shock feel identical in the newspaper and behave nothing alike at a central bank. When demand falls, prices and output move the same direction, and easing is uncomplicated. A tariff raises measured prices while reducing output. Easing into that risks unanchoring expectations, so the central bank waits. That is exactly the bind the Bank of Canada described on 2 September: upside inflation risk up, growth prospects more uncertain, policy unchanged.

You can see the price side arriving in the national accounts. Statistics Canada's second-quarter release of 28 August reports the GDP deflator up 2.5%, the largest increase since the second quarter of 2022, led by export prices up 6.5% following a substantial rise in international oil prices. Exports rose 3.6% in the quarter, led by passenger cars and light trucks at +27.0%, coinciding with a rebound in auto production in Canada. Ontario builds those vehicles.

So the honest summary for a borrower is that bad trade news is not automatically cheap-money news. The next Consumer Price Index release lands 14 September with August data, and it will tell us more about whether the 22 August measures are showing up at the till yet. Anyone making a five-year decision on a forecast of what that print will say is guessing.

Two channels: pricing is weak and indirect, income is strong and direct

There are two different machines here and people routinely mix them up. The Bank's overnight target feeds prime, and prime feeds variable-term mortgages, which compound monthly. Fixed-term pricing is not set by the Bank at all — it comes off Government of Canada bond yields of matching term, plus a lender spread covering funding, credit, prepayment risk and margin. That is why a hold announcement and a move in five-year offers can happen in the same week, in opposite directions. Knowing the Bank is on hold tells you very little about what a five-year offer will look like next month.

The second channel is the one the economics notes never describe, and it is far stronger for the households actually exposed. Salaried full-time income is underwritten at face value. Reduced hours under a Work-Sharing arrangement, EI benefits and severance-period income are treated very differently — typically averaged, discounted, or excluded outright depending on the lender and the insurer. A household can have an unchanged credit file, unchanged equity, and a completely changed approval outcome.

Meanwhile the labour data has not yet shown the damage. Statistics Canada's August Labour Force Survey, released 4 September, reports employment down 42,000 nationally with joblessness unchanged at 6.4% — against 7.1% in August 2025. Manufacturing was the only sector with a significant increase, up 22,000, with most of that, 14,000, in Ontario. Ontario employment edged down 18,000 in the month, after a net gain of 119,000 from March to July, and was up 116,000 year over year.

That is a striking set of numbers to sit beside a 50 per cent tariff taking effect on 22 August. It may deteriorate. It has not yet. What it means practically is that files in Waterloo Region are unusually split: an employment base with real manufacturing exposure sitting next door to a tech and post-secondary sector a tariff does not touch. Two households on the same street can face entirely different exposure, and a general economic view is useless for telling them apart.

• A reduced-hours letter from an employer, showing the arrangement and its expected duration
• Work-Sharing participation details, since the treatment of that income is not the same as salary
• EI benefit statements, and whether benefits are being drawn alongside severance
• Two or three years of history where hours have always been variable, so an average can be established
• Year-to-date pay records that still show pre-reduction income, if the change is recent

The renewal arithmetic, done properly

Take a household that borrowed $500,000 in 2021 on a five-year fixed term at 1.99% with a 25-year amortization. Canadian fixed mortgages compound semi-annually, so the effective monthly factor is (1 + 0.0199/2)^(1/6) − 1, or 0.16515% — not 1.99 divided by twelve. The payment is $2,114.84 and the balance at maturity is $418,762.92. Renewing that balance over the remaining 20 years looks like this.

• At 3.99%: $2,528.19 a month, an increase of $413.35
• At 4.49%: $2,637.69 a month, an increase of $522.84
• At 4.99%: $2,749.54 a month, an increase of $634.69
• At 5.49%: $2,863.67 a month, an increase of $748.83

The useful part of that table is not any single line, because none of us knows which line applies in your renewal month. It is the sensitivity. On this balance a quarter-point difference in the cost of borrowing is $55.63 a month and a half-point is $111.85. That is the correct way to think about a trade war: as a range you can absorb or cannot, rather than a forecast you act on.

The stress test still applies on top. Uninsured files qualify at the greater of the contract offer plus two percentage points or 5.25%, so a 4.49% offer is tested at 6.49% — a payment of $3,098.55 over 20 years. That is the figure the underwriter measures your income against, not the payment you would make. Our calculators will run your own balance through the same arithmetic.

For context, CMHC's 2026 Mortgage Consumer Survey found 39% of mortgage consumers concerned about making their payments, down from 53% in 2025, and reported that households who renewed saw payments increase by an average of $375 a month. That average sits below every line in the table above, which is a reminder that averages include smaller balances and shorter remaining amortizations than a 2021 Waterloo Region purchase.

What we would do with a file this month

First: if your term matures within the next year, start now rather than at the letter. The renewal window opens 120 days out, and the value of starting early is not the shopping — it is having the documentation problem found while there is still time to solve it.

Second, and this is where the usual advice is wrong: the standard line to a tariff-exposed household is wait, and refinance later when things settle. For a household whose hours are about to be cut, waiting is the expensive choice. Approvals are granted on the income you can evidence today, not the income you had last spring. If a file genuinely needs restructuring — consolidating a line of credit, lengthening an amortization, funding a gap — the window is while the income documentation is still clean.

Third, be clear about which transaction you are doing. Staying with your incumbent lender at maturity, moving the same balance and amortization to a different lender, and increasing the balance are three different transactions with three different qualifying requirements. People use "renew" for all three and then get surprised by the paperwork on the one they actually chose.

On the local market itself, Cornerstone Association of REALTORS® reported for July that Waterloo Region sales were down 10.0% year over year with new listings down 14.3%, and that at 3.9 months the region had the lowest months of supply across Cornerstone's market areas — though inventory remained well above the 10-year July average of 1.92 months. That is July data, and it is Cornerstone's, not ours.
