What Affects Mortgage Rates in Canada?
What affects mortgage rates in Canada: bond yields, the Bank of Canada policy rate, inflation, your credit, down payment, term, and lender competition.
What affects mortgage rates in Canada is a mix of economy-wide forces and facts about you. At the market level, fixed rates track Government of Canada bond yields and variable rates track the prime rate, which follows the Bank of Canada policy rate. At the lender level, funding costs and competition shape the spread you are offered. At the borrower level, your credit, down payment, property, and term determine how much of a discount you qualify for.
Understanding which forces are in play helps you tell the difference between a rate move you can act on and one you simply have to live with until your next decision point.
Market forces: bond yields and the policy rate
The single largest influence on a fixed mortgage rate is the yield on Government of Canada bonds, especially the five-year benchmark that sits behind a five-year fixed term. When bond yields rise, lenders pay more for long-term funding and fixed mortgage rates tend to follow. When yields fall, fixed rates can soften, sometimes before the central bank moves at all.
Variable rates are tied to prime, which usually changes when the Bank of Canada changes its policy rate. The full transmission path is set out in how mortgage rates work in Canada and, for the policy rate specifically, in the Bank of Canada policy rate guide.
Inflation and the economic backdrop
Inflation is the reason central banks move policy rates in the first place. When inflation runs above the Bank of Canada's target, the Bank tends to lean toward higher rates to cool demand; when inflation is subdued and the economy is weak, it tends to lean the other way. Those expectations are already embedded in bond yields, which is why fixed rates can move on an inflation report rather than on a rate announcement.
Employment, wage growth, global bond markets, and the exchange rate all feed the same calculation. You cannot control any of them, but watching them tells you which direction the pressure is coming from and whether your quoted rate is likely to hold.
Lender-level factors: funding costs and competition
Each lender adds its own spread on top of the market reference. That spread covers its funding mix, operating costs, and profit, and it widens or narrows with competition. When lenders compete for volume, discounts get deeper; when funding is tight, they pull back.
This is why the same policy environment can produce noticeably different offers across banks, credit unions, and broker channels. Comparing more than one channel is the practical response, and the rate comparison guide covers how to do it without being misled by the headline.
Borrower-level factors: credit, down payment, and property
Your own file sets the discount you are offered. A stronger credit score, a larger down payment, stable income, and a straightforward property all tend to earn a better rate, because they reduce the lender's risk. The table below summarises the main borrower-side levers.
| Factor | How it affects your rate | What you can do |
|---|---|---|
| Credit score | Stronger credit usually earns a larger discount | Check your report and fix errors before applying |
| Down payment | A lower loan-to-value ratio reduces lender risk | Save a larger down payment where possible |
| Income stability | Salaried, documented income is easier to price | Prepare clear proof of income |
| Property type | Some properties are considered higher risk | Ask how the lender classifies the home |
| Debt load | Heavier existing debt can raise your rate or reduce options | Reduce balances before applying |
If your down payment is below the threshold that requires it, mortgage default insurance applies and changes the lender's risk calculation. The mortgage default insurance guide explains how that works.
How the mortgage itself changes your rate
The product you choose carries its own pricing. A longer term usually costs more than a shorter one when the yield curve slopes upward, because the lender is committing for longer. A variable rate is priced differently from a fixed rate. A longer amortization can raise the rate on an insured mortgage. And a mortgage on a rental or non-owner-occupied property is typically priced higher than one on your principal residence.
These are choices you make, not forces imposed on you, so they belong in the comparison. Model how they change your payment with the fixed vs variable calculator or the mortgage affordability calculator.
What you can and cannot control
- You cannot control bond yields, inflation, or the policy rate.
- You can control your credit score, debt load, down payment, and choice of term and rate type.
- You can control how many lenders you compare and how well you read the contract.
- You can control when you commit, within the limits of your purchase timeline.
One more lever is timing. If you are not under pressure to buy, you can watch the market and choose when to commit, though no one can predict the next move with confidence. Treat any forecast as an opinion, and make your decision on whether the payment is comfortable at the rate you are actually offered rather than at a rate you hope to get.
Focus on the levers you own, and confirm the current market figures on the Bank of Canada website rather than assuming last month's rate still applies. The federal stress test also means the rate you qualify at can differ from the rate you pay, which affects what you can actually borrow even when the headline rate looks attractive.
Frequently asked questions
What is the biggest factor affecting mortgage rates in Canada?
For fixed rates, Government of Canada bond yields are the biggest market factor, because they reflect the lender's long-term funding cost. For variable rates, the prime rate and the Bank of Canada policy rate dominate. Your own credit, down payment, and property then determine how large a discount you receive on top of those market references.
Do mortgage rates go up when the Bank of Canada raises rates?
Variable rates usually rise, because prime typically follows the policy rate. Fixed rates may already have moved, since they track bond yields and those yields often price in a rate change before it happens. A policy increase does not automatically raise a fixed mortgage rate, which is set for the term.
Does my credit score affect my mortgage rate?
Yes. A stronger credit history generally earns a larger discount off the posted rate, while weaker credit can mean a higher rate, fewer lender options, or the need for a co-signer. Check your credit report for errors well before you apply, and reduce existing debt balances, since both can improve the rate you are offered.
Why are mortgage rates different at different lenders?
Each lender applies its own spread over the market reference, based on its funding mix, operating costs, and how aggressively it is competing for business. That is why the same economic conditions can produce different offers across banks, credit unions, and broker channels. Comparing several lenders on the same day is the practical way to see the range.
