Qualifying & Pre-Approval
Mortgage Broker vs Bank: Which Should You Use?
Compare mortgage broker vs bank in Canada: how each works, who they serve, and how the stress test and qualification rules affect your mortgage choice.
Choosing between a mortgage broker and a bank is one of the first decisions you make when financing a home in Canada, and the mortgage broker vs bank question usually comes down to how many options you want to see and how much of the paperwork you want to handle yourself. A broker shops your file across multiple lenders, while a bank typically presents its own products first. Both are regulated, both must follow federal lending rules, and neither can guarantee approval.
What matters more than the sign on the door is whether the person arranging your mortgage understands your income type, your credit profile, and the property you want to buy.
How a Mortgage Broker Works
A mortgage broker is an intermediary. Rather than lending you money, they submit your application to lenders on their approved panel, which can include big banks, credit unions, monoline lenders, and private lenders. Because they deal with many institutions, they can compare policies side by side: how each one treats overtime income, rental income, self-employment income, or a past credit hiccup.
Brokers are licensed and regulated at the provincial level, and they generally must disclose how they are paid and which lenders they approached. In most cases the lender pays the broker a finder's fee, so you often pay nothing directly for a standard residential mortgage. That is not universal. Unusual properties, bruised credit, private lending, or very small loans may come with a broker fee, and any fee must be disclosed to you in writing before you commit.
How a Bank or Direct Lender Works
When you walk into a bank, you are talking to an employee of the lender. That person can offer that institution's own mortgage products, plus any exceptions internal policy allows. The advantage is simplicity: one relationship for your chequing account, savings, credit card, and mortgage, sometimes with a bundle discount attached.
The trade-off is scope. A bank mortgage specialist cannot show you a competitor's product, even if it would fit you better. If your situation is straightforward, meaning salaried income, solid credit, a healthy down payment, and a standard property, a single lender may well be competitive.
Banks and other federally regulated lenders also operate under OSFI Guideline B-20, which sets expectations for residential mortgage underwriting.
Mortgage Broker vs Bank: Side by Side
| Factor | Mortgage broker | Bank or direct lender |
|---|---|---|
| Products shown | Many lenders on their panel | That institution's own products |
| Who they represent | You, and usually paid by the lender | The lender |
| Typical cost to you | Often none for standard files; any fee disclosed | No broker fee; lender may charge its own fees |
| Best for | Comparing options, complex income, credit issues | Simple files, existing relationship, bundle discounts |
| Speed | Depends on lender turnaround times | Often quick if you are an existing client |
The Stress Test and Qualification Rules Apply Either Way
Whoever arranges your mortgage, you still have to qualify under the federal mortgage stress test. For most mortgages at federally regulated lenders, you must show you could afford payments at the higher of your contract rate plus two percentage points or the published qualifying-rate floor. Confirm the current floor with OSFI or your lender, because it can change.
Lenders also measure two ratios. GDS compares housing costs to gross income, while TDS adds all your other debt payments. Insured mortgages also fall under CMHC or other default insurance rules, which set limits on amortization and loan-to-value. Read more on GDS and TDS ratios and on how the stress test works.
Rates, Fees, and How Brokers Get Paid
Rate is the most visible difference, but it is not the whole picture. A broker can often access wholesale rates from monoline lenders that have no branch network, and those rates can be lower than a posted bank rate. Banks counter with relationship pricing, rate holds, and the convenience of a single login.
Look past the headline rate at the mortgage contract itself: prepayment privileges, portability, the penalty formula if you break early, and whether the rate is fixed or variable. If you choose a variable rate, your payment moves with the lender's prime rate, which in turn responds to the Bank of Canada policy rate. Penalties on fixed-rate mortgages are often calculated using the interest rate differential (IRD), which can be far larger than three months of interest. Understand how IRD penalties are calculated before you sign.
Which Option Fits Your Situation?
- Straightforward file: a bank, credit union, or broker may all land near the same place, so compare at least one alternate quote.
- Self-employed or variable income: brokers often know which lenders accept business financials or alternative income proof. See mortgages for self-employed Canadians.
- Bruised credit: broker panels usually include lenders that work with past credit issues, which can widen your options.
- Existing relationship and bundle discounts: a bank may be competitive once account and credit card pricing is factored in.
- Tight timeline: ask each side how quickly they can produce a commitment, since lender turnaround varies.
Questions to Ask Either Way
Ask how the person is paid and whether any fee comes out of your pocket. Ask which lenders were compared and why the recommended one won. Ask what the penalty would be if you broke the mortgage in year two, and whether the mortgage is portable or assumable if you move.
Finally, get a mortgage pre-approval before you shop seriously, and run your numbers through a stress test calculator to see the payment you would need to qualify for. A pre-approval is not a full approval, and it does not obligate a lender to fund your purchase.
Frequently asked questions
Is a mortgage broker better than a bank?
Not inherently. A broker can compare many lenders and may suit complex income or credit files. A bank can be competitive for simple, salaried files with an existing relationship and bundle discounts. Both must apply the federal stress test and the same qualification ratios, so the better choice depends on your situation rather than the label.
Do mortgage brokers cost more than a bank?
Usually not for a standard residential mortgage, because the lender pays the broker a finder's fee. Some files, such as private lending, unusual properties, or very small loans, may carry a broker fee that must be disclosed in writing. Banks generally do not charge a broker fee, but they may charge their own lender fees or discharge costs.
Can a mortgage broker get me a lower rate than my bank?
Sometimes. Brokers can access wholesale rates from monoline lenders without branch networks, which can beat a posted bank rate. Banks may respond with relationship pricing or rate holds. Always compare the full contract, including prepayment privileges and early payout penalties, not just the headline rate.
Do I qualify differently with a broker than a bank?
The federal stress test and GDS and TDS ratios apply to both. What changes is lender policy: brokers can match your file to institutions that accept your income type or credit history, while a single bank only applies its own rules. Neither route can guarantee approval, so confirm requirements before you rely on any pre-approval.
