Mortgage Broker vs. Going Direct to a Bank

When you get a mortgage in Canada, you can either walk into your own bank and apply with their mortgage specialist, or you can work with an independent mortgage broker. Both can arrange a mortgage — but the way they're paid, the lenders they can access, and the advice you get are meaningfully different.

What a bank mortgage specialist does

A bank mortgage specialist is an employee of one lender. They can only offer that bank's mortgage products, their bank's rates, and their bank's approval policies. They're compensated by the bank — usually a mix of salary and internal volume incentives — so their goal is to close mortgages for their employer.

This is efficient when:

You have a strong, straightforward file (T4 income, good credit, standard down payment).
You already bank there and want your mortgage tied to your everyday accounts.
The posted rate is competitive and the bank is willing to discount for your profile.

What a mortgage broker does

A mortgage broker is independent and licensed provincially. They collect your financial information once and shop it across dozens of lenders — the big banks, credit unions, monoline lenders (that only fund mortgages through brokers), and, when appropriate, alternative or private lenders. They then present the offers that actually fit your situation.

Brokers in Canada are almost always paid by the lender, not by you, on standard residential deals. The lender pays a finder's fee once the mortgage funds. For the client, the service is typically free. On alternative or private deals, or unusual files, there may be a broker fee — but it has to be disclosed to you up front in writing.

The practical differences

Lender access. A bank offers one lineup. A broker can compare rates and policies from many lenders in a single application.
Flexibility on the file. If you're self-employed, on contract, newly arrived in Canada, rebuilding credit, buying a rental, or borrowing near the top of your ratios, brokers usually have more lenders willing to look at the file.
Rate negotiation. Brokers negotiate on your behalf across lenders. Banks negotiate against their own posted rate. Which produces the lower rate depends on your profile and the lender's current appetite.
Prepayment and portability terms. Bank branded mortgages sometimes have stricter penalty calculations (the infamous IRD) than broker-channel monoline lenders. It's worth comparing the fine print, not just the headline rate.
Renewals and switches. At renewal, your existing bank sends a renewal letter with an offer — often not their best rate. A broker can shop the renewal across lenders to see whether switching is worth it.

When going direct to a bank makes sense

You want everything under one roof and value the branch relationship.
Your file is simple and the bank has already quoted you a strong discounted rate.
You want a specific product only that bank offers (e.g., a readvanceable HELOC combo).

When a broker makes sense

You want to compare offers from many lenders without applying separately to each.
Your income is self-employed, commission, contract, or otherwise non-standard.
You've been declined or lowballed by your bank.
You're near a stress-test or ratio limit and need a lender with the right policy.
You're refinancing, buying a rental, or dealing with an unusual property.

How to decide

The honest answer for most buyers is: get a quote from your own bank and talk to a broker, then compare. The bank's offer sets a floor. The broker's job is to beat it — on rate, on terms, or on approval odds — across the rest of the market. If the bank wins, take it. If the broker finds something better, take that.

The one thing not to do is take the first offer from any single lender without benchmarking it. Over a 5-year term, even a 0.25% rate difference on a $500,000 mortgage is roughly $6,000 — real money that a 20-minute comparison can capture.
