Mortgage Broker vs Bank in Canada: Which Should You Choose?

Why use a mortgage broker instead of a bank?

The case for a broker comes down to five practical advantages.

• Choice. 100+ lenders instead of one. That includes monoline lenders, which do mortgages only, have no branches and are reached only through brokers. They often price competitively and tend to calculate fixed-rate break penalties more fairly than big banks, which often use their posted rate in the interest rate differential (IRD) formula.

• Negotiating leverage. A brokerage places volume with its lenders and puts several of them in competition for one file. A walk-in borrower negotiating alone has neither advantage.

• One credit check. A broker pulls your credit once and uses that report to shop multiple lenders, so you avoid a string of separate inquiries from applying at several banks yourself.

• Matching your file to the right rules. Every lender treats income, credit and property types differently. A broker knows which lenders accept self-employed income, newcomer files, bruised credit or rental properties, and packages the file the way that lender wants to see it. That can be the difference between approval and decline on the same numbers.

• Advice on the whole mortgage, not just the rate. Prepayment privileges, penalty calculations, portability and whether the mortgage is registered as a standard or collateral charge all affect what it costs you over time. You can see where pricing sits on our current mortgage rates page, but the rate you're offered depends on your credit, down payment, income and property.

How brokers get paid, and what a bank mortgage costs you

The usual worry is that a broker must be adding a cost somewhere. On a standard prime mortgage, they aren't. The lender pays the broker a finder's fee when your mortgage funds, as its cost of getting business through the broker channel instead of its own branches. Your rate is set by the lender's pricing and your profile, not by the fee, so the shopping, advice and negotiation are typically free to you.

A bank pays for its own sales channel too. Its mortgage specialists and branches are paid by the bank, and that cost is built into how the bank prices its mortgages. You just never see it itemized, and you can't shop it around.

There are real exceptions on the broker side. On private mortgages, some alternative-lender files and complex or urgent deals, the lender may pay little or nothing, so a broker fee can apply. In Ontario, FSRA requires licensed brokerages to disclose compensation and any conflict of interest in writing before you commit, so any fee reaches you as a dollar figure you can accept or decline.

When going to your bank makes sense

A fair comparison has to name the cases where a bank wins, or at least ties.

• You're a strong, straightforward borrower who negotiates. Salaried income, strong credit and a solid down payment put you in the bank's sweet spot. If you push hard, your bank may match what a broker finds, and a broker quote gives you something concrete to negotiate with.

• You want everything under one roof. Some borrowers value having chequing, investments, credit cards and the mortgage at one institution, with one login and an in-branch contact.

• You need a product only your bank offers. Not every lender works with brokers, so a few bank-specific products or promotions are available only at the branch.

• You want a branch. Monoline lenders serve clients by phone and online. If sitting across a desk from your lender matters to you, that's a legitimate preference.

Even then, comparing costs you nothing. A broker quote alongside your bank's offer tells you whether the convenience is free or whether you're paying for it.

The drawbacks of using a broker, and how to avoid them

Brokers aren't automatically better, and the common criticisms deserve a straight answer.

Quality varies. A broker is only as useful as their lender access, their experience with files like yours and how clearly they explain your options. Ask which lenders they'd recommend for you and why, and what the runners-up offered. In Ontario you can confirm any brokerage or agent on FSRA's public registry; ours is brokerage licence #13737.

Lender compensation can differ. Some lenders pay volume bonuses or trailer fees, and a poorly run brokerage could let that steer recommendations. That's why the written compensation disclosure matters, and why you should expect a recommendation explained in terms of rate, penalties, prepayment privileges and approval odds.

The person on your file may be an agent, not a broker. That's normal, and in Ontario both hold FSRA licences. For the licensing detail, including how a bank mortgage specialist fits in, read mortgage broker vs mortgage agent vs specialist.

Renewal: where the broker vs bank gap is widest

Many borrowers compare carefully when they buy, then sign whatever renewal letter their lender mails years later. The first renewal offer is rarely the most competitive one available, because your lender knows switching feels like work.

The rules now make shopping easier. Renewing with your current lender doesn't require you to requalify. And since November 21, 2024, a straight switch to a new lender at renewal, keeping the same balance and the same amortization, no longer requires the stress test, whether the mortgage is insured or uninsured. The stress test still applies if you add money or extend the amortization. So a broker can put your current lender's offer up against the wider market without the qualifying hurdle that used to keep people from moving.

Start comparing a few months before your maturity date so there's time to switch if it makes sense. Our guide to mortgage renewal in Canada walks through the timeline and what to ask.

How to compare a broker and your bank side by side

You don't have to choose on theory. Run both options and let the numbers decide.

1. Get your bank's written offer. Ask for the rate, term, amortization, prepayment privileges, how the penalty is calculated, and whether the mortgage is a standard or collateral charge.

2. Get a broker quote on the same terms. Same term, amortization and down payment, so the comparison is fair. Ask which lenders the broker considered and why they recommend one.

3. Compare the full cost, not just the rate. A slightly lower rate with a harsh penalty or weak prepayment privileges can cost more if you sell, refinance or break the mortgage mid-term.

4. Check for fees. On a standard deal there should be no broker fee. If one applies, it must be disclosed in writing before you commit.

5. Decide. If your bank is close, it may improve its offer once it sees a competing quote. If the broker's option wins, the broker handles the application and paperwork through to closing.
