How Mortgage Rates Work in Canada: The Complete Guide (2026)

Mortgage rates feel like a single number you either get or you don't — but in 2026 the rate you're offered is the end result of several moving parts: what it costs your lender to raise money, how risky your file looks, what kind of mortgage you're getting, and how much margin the lender wants to keep. Understanding those parts is the difference between accepting whatever shows up on a screen and negotiating from a position of knowledge. This guide walks through exactly how Canadian mortgage rates are built, why fixed and variable rates move for completely different reasons, and where a broker can actually shave money off your cost.

The short answer

In Canada, fixed mortgage rates track Government of Canada bond yields, while variable rates move with your lender's prime rate, which follows the Bank of Canada's policy interest rate. On top of that base cost, lenders add a risk premium and a profit margin, then adjust the price depending on whether your mortgage is insured, insurable, or uninsured. That's why two borrowers can get very different rates on the same day — and why the advertised "best rate" is rarely the rate most people actually qualify for. To see where the market sits today, check current rates.

Fixed vs. variable: two different engines

The single most important thing to understand about Canadian rates is that fixed and variable are priced off completely different benchmarks. They don't move together, and they don't respond to the same news.

Fixed rates follow bond yields

When a lender gives you a fixed rate, they need money they can lend out for the full term at a known cost. They effectively fund that lending in the bond market, so the price of a fixed mortgage tracks the yield on Government of Canada bonds of a similar term — the 5-year bond yield for a 5-year fixed, for example. When investors pile into bonds (often during economic uncertainty), yields fall and fixed mortgage rates tend to drift down a few weeks later. When yields rise, fixed rates follow. Notably, the Bank of Canada cutting or holding its policy rate does not automatically move fixed rates — bond markets may have already priced that in, or may be reacting to inflation expectations instead.

Variable rates follow the Bank of Canada

A variable rate is quoted as your lender's prime rate minus a discount (for example, "prime minus 0.90%"). Prime is set by each lender but moves almost in lockstep with the Bank of Canada's overnight policy rate. When the Bank raises or lowers that rate at one of its scheduled announcements, lenders adjust prime within days, and your variable rate moves with it. You can read more about how that mechanism works on our prime rate page.

Feature	Fixed rate	Variable rate
Tied to	Government of Canada bond yields	Lender prime rate / Bank of Canada policy rate
Payment stability	Locked for the term	Changes when prime changes (or amortization shifts)
Moves on	Bond market sentiment, inflation expectations	Bank of Canada rate announcements
Typical break penalty	Interest rate differential (can be large)	Usually three months' interest
Best for	Certainty, tight budgets	Flexibility, tolerance for swings

Because the two are priced independently, it's entirely normal for fixed rates to fall while variable holds, or vice versa. If you want a forward-looking read on where each may head, see our mortgage rate forecast.

How lenders actually set a rate

Underneath the benchmark, every lender builds your rate from three layers. Knowing them helps you understand why rates differ between lenders and why your file matters.

1. Cost of funds

This is the base — what it costs the lender to obtain the money they're lending you. For fixed, that's anchored to bond yields; for variable, to the policy rate. A lender can't price below its cost of funds for long, which is why no lender can sustainably beat the market by a wide margin.

2. Risk premium

The lender then adds a premium based on how likely you are to repay and how easily they could recover their money if you didn't. A strong credit score, a stable income, a large down payment, and an easy-to-sell property all lower this premium. A bruised credit history, self-employment income that's harder to verify, a rental property, or an unusual home all raise it.

3. Margin

Finally, the lender adds its own profit margin. This is the layer with the most room to negotiate, and it's where channel matters: lenders that sell only through brokers often run leaner margins because they don't carry expensive branch networks, while a big bank's posted rate bakes in a wide margin it expects most walk-in customers to accept.

Insured, insurable, and uninsured: the pricing tiers

One of the most counterintuitive facts in Canadian mortgages is that the lowest rates often go to borrowers with the smallest down payments. That's because of default insurance.

Insured

If your down payment is less than 20%, you're legally required to carry mortgage default insurance (from CMHC, Sagen, or Canada Guaranty). You pay the premium, but the lender's risk is effectively removed — if you default, the insurer makes them whole. Because the loan is government-backed, the lender can fund it more cheaply, so insured mortgages typically carry the lowest rates.

Insurable

If you put down 20% or more on a property under $1 million with an amortization of 25 years or less, the lender can still purchase "portfolio" insurance on the loan in the background (you don't pay for it). These insurable mortgages usually price between insured and uninsured.

Uninsured

If the mortgage can't be insured — a refinance, a property over $1 million, an amortization longer than 25 years, or a rental — the lender carries the full risk and prices it accordingly. Uninsured mortgages generally carry the highest rates of the three tiers, often by a meaningful margin.

Tier	Typical scenario	Relative rate
Insured	Down payment under 20%	Lowest
Insurable	20%+ down, under $1M, ≤25-yr amortization	In between
Uninsured	Refinance, $1M+, 30-yr amortization, rental	Highest

Why your rate differs from the advertised one

The eye-catching rate in an ad is almost always the insured, owner-occupied, perfect-credit, lowest-margin scenario — the best case the lender can legally print. Your actual rate is adjusted for your real situation: a 20%-plus down payment can ironically raise it (because you're now uninsured or insurable rather than insured), a rental property adds a premium, a longer amortization adds a premium, and a refinance pushes you into the uninsured tier. None of this is a bait-and-switch — it's the pricing tiers doing exactly what they're designed to do. The lesson is to compare rates for your scenario, not the headline.

The stress test's effect on your rate (and approval)

The stress test doesn't change the rate you pay, but it changes the rate you must qualify at. Federally regulated lenders must approve you at the higher of your contract rate plus 2% or the minimum qualifying rate of 5.25%. So if you're offered a 4.5% mortgage, the lender checks that your income could still carry the payments at roughly 6.5%. This caps how much you can borrow and indirectly influences product choice — some borrowers move to a longer amortization or a different lender tier specifically to pass. It does not make your rate higher; it makes your approved loan amount smaller. You can model this with our mortgage payment calculator.

How a broker gets you a lower rate

A broker doesn't have a secret rate that doesn't exist elsewhere — what they have is access to dozens of lenders at once and knowledge of which lender prices each scenario most aggressively. A monoline lender might be sharpest on insured purchases this week; a credit union might own the uninsured refinance space; a particular bank might be running a quiet promotion. Because broker-channel lenders often run leaner margins, the starting point is frequently lower than a posted bank rate. The broker also packages your file so it lands in the best pricing tier the rules allow, which can matter more than the rate negotiation itself.

Worked example: what a small rate difference costs

Consider a $500,000 mortgage on a 25-year amortization. Compare a rate of 4.49% against 4.99% — half a percentage point.

• At 4.49%: roughly $2,766 per month.
• At 4.99%: roughly $2,909 per month.
• Difference: about $143 per month, or roughly $1,716 a year — and about $8,580 over a 5-year term.

(These figures are illustrative, not current rates. Run your own numbers with the payment calculator.) Half a point sounds trivial in conversation and is anything but on paper, which is exactly why which pricing tier you land in — and which lender you land with — is worth getting right.

Frequently asked questions

Why did fixed rates move but variable didn't (or vice versa)?

Because they're priced off different benchmarks. Fixed rates follow Government of Canada bond yields, which react to inflation expectations and market sentiment, while variable rates follow the Bank of Canada's policy rate. One can move without the other.

Does a bigger down payment always mean a lower rate?

No — and this surprises people. Putting down less than 20% makes your mortgage insured, which is the lowest-priced tier. Going to 20%-plus can move you into the insurable or uninsured tier, which sometimes carries a slightly higher rate even though you're borrowing less.

Does the Bank of Canada set mortgage rates?

Only indirectly, and only for variable rates. The Bank sets the overnight policy rate, which drives lender prime and therefore variable mortgage rates. Fixed rates are set by the bond market, not the Bank.

What is the stress test and does it raise my rate?

It doesn't raise your rate. It requires lenders to qualify you at the higher of your contract rate plus 2% or 5.25%, which limits how much you can borrow but leaves the rate you actually pay unchanged.

Can a broker really beat my bank's rate?

Often, yes — not through a hidden rate, but by shopping dozens of lenders, including broker-only lenders with leaner margins, and by structuring your file so it qualifies for the best pricing tier the rules allow.
