Choosing between a mortgage broker and a bank comes down to how many lenders you can reach and who pays for the help. A broker shops one application across a panel of lenders and is usually paid by the lender that funds the mortgage, while a bank can only offer its own products.
If you are weighing a mortgage broker against going straight to your own bank, the practical difference is access and who pays for the help. A broker can submit one application to several lenders, while a bank branch can only offer that bank's own mortgage products. The better route depends on how straightforward your file is, how much you value convenience, and how willing you are to compare loan terms rather than just a headline rate.
| Factor | Mortgage broker | Bank |
|---|---|---|
| Lenders available | A panel that may include banks, monoline lenders, credit unions, trust companies and private lenders | Only the products of that one institution |
| Who pays for the help | Usually the lender pays the brokerage a commission after funding; some files carry a borrower fee | The bank is paid through the interest and fees on the mortgage |
| Application process | One application, shopped to multiple lenders | One application, one credit decision |
| Typical strength | Comparison, unusual files, several lenders competing at once | Relationship pricing, bundling, familiar service and in-branch support |
| Regulation | Licensed provincially, with rules that differ from province to province | Federally regulated banks supervised by OSFI; provincially regulated credit unions fall to provincial regulators |
What a mortgage broker actually does
A mortgage broker — or an agent working under a brokerage — is an intermediary, not a lender. The brokerage holds relationships with a panel of lenders. That panel can include chartered banks, monoline lenders that sell only through brokers, credit unions, trust companies and, for harder files, alternative and private lenders. When you apply, the broker reviews your income, down payment, credit history and property, then works out which lenders on the panel are likely to approve and on what terms.
From there the broker packages the file: gathering documents, arranging an appraisal if one is needed, submitting to one or more lenders and negotiating on your behalf. The lender funds the mortgage and holds it; the brokerage is paid once the deal closes. Brokers are licensed in the province where they do business and must follow that province's rules on disclosure and conduct, so a broker registered in one province may not be able to arrange a mortgage on a property in another without the correct registration.
How the bank route works
Walking into a bank means dealing with one product shelf. A branch mortgage specialist or advisor can explain that bank's fixed and variable rate mortgages, its prepayment privileges and its lending criteria — but if your file does not fit, there is no plan B inside that building. The upside is convenience: you may already bank there, your paycheque and savings are visible to the lender, and staff can bundle a mortgage with a chequing account or a line of credit. Some institutions offer relationship pricing that a broker cannot access.
Two things are worth keeping in mind. First, a bank mortgage specialist is paid by the bank, not by you; the role is a sales role with targets. Second, banks are federally regulated and supervised by the Office of the Superintendent of Financial Institutions, and the underwriting expectations in OSFI's residential mortgage guideline apply to them, including the qualifying requirements commonly called the stress test. Credit unions and some other lenders are provincially regulated and can operate under different rules. The Financial Consumer Agency of Canada publishes plain-language guidance on how mortgages work and what lenders must tell you.
How mortgage brokers get paid
In the most common arrangement, the lender pays the brokerage a commission once the mortgage funds, plus in some cases a smaller ongoing payment for servicing the mortgage. That is why borrowers often describe a broker as free. It is more accurate to say the cost is built into the mortgage pricing rather than invoiced to you directly.
There are exceptions. If your file cannot be placed with a lender that pays a standard commission — a private mortgage, a property that is hard to appraise, or a borrower with serious credit problems — the broker may charge you a fee, or the lender may charge a lender fee added to the mortgage balance. Any such fee must be disclosed before you commit, and federally regulated lenders must disclose the full cost of borrowing. The FCAC explains those disclosure rules in its material on loans.
Because commissions come from lenders, ask how your broker is compensated and whether any lender on the panel pays more than another. That does not mean brokers steer clients unfairly, but you should understand the incentive. Provincial disclosure requirements differ, so ask for the answer in writing and compare total cost of borrowing rather than rate alone.
Rate, terms and the fine print that costs money
A lower rate is only one part of a mortgage. Two mortgages at the same rate can cost very different amounts if one restricts prepayments, limits portability or charges a large penalty for breaking the term early. On fixed-rate mortgages, penalties are often calculated as the greater of three months' interest or an interest rate differential, and that calculation varies by lender — some use the posted rate, which can produce a much larger penalty than the discounted rate you actually pay.
This is where comparison shopping pays off. Ask both a broker and a bank the same questions in writing: how is the penalty calculated, how much can I prepay each year, can I increase payments, can I port the mortgage if I move, is the mortgage assumable, and what happens at renewal. Then use a loan payment calculator to see what different rates and amortizations do to your monthly payment and your total interest.
Which route suits which borrower
Neither channel is universally better. The fit depends on your file and your preferences.
- A bank may suit you if you have steady salaried income, a solid credit history, a down payment you can document and an existing relationship with the institution. You value one point of contact, in-person service, and the ability to bundle products.
- A broker may suit you if your income is variable or self-employed, you have a credit blemish, you are buying a rental or unusual property, or you are new to Canada. Brokers also help if you simply want several lenders competing on the same application. If your credit has taken a hit, start with our guide to bad credit loans before you approach a mortgage lender.
- Either route works if you are organized, have your documents ready and are willing to ask hard questions about penalties and prepayment terms.
Co-signers, guarantors and joint borrowers
If a parent, partner or friend will be on the application, the channel matters less than the paperwork. Adding a co-signer or guarantor can strengthen an application, but it also creates legal obligations that outlast the purchase. Lenders must give joint borrowers certain disclosures about their rights and obligations, which the FCAC sets out in its guidance on disclosure of information to joint borrowers. Read our explainer on what a co-signer is before you agree to be one, and make sure both the broker and the bank explain who is liable if payments stop.
Common mistakes to avoid
- Choosing on rate alone and ignoring penalty calculations, prepayment limits and portability.
- Applying to many lenders yourself, which can create a scatter of credit inquiries instead of one organized application.
- Assuming a broker can access every lender; panels differ, and some institutions work mainly through their branches.
- Not asking how the broker or mortgage specialist is paid, and whether any fee will land on you.
- Signing a broker agreement without reading the terms about fees, exclusivity or cancellation.
- Adding a co-signer without explaining the risks to them, or without confirming what the lender will disclose.
- Forgetting closing costs — appraisal, legal fees, title insurance, land transfer tax or registration fees — when working out what you can afford.
In short, a broker is a shopping service paid mainly by lenders, while a bank is a single supplier paid through your mortgage. If your file is simple and you like your bank, the branch route can be efficient. If you want lenders competing, or your situation is complicated, a licensed broker usually widens your options — as long as you ask about compensation and compare the whole mortgage, not just the rate.
