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

The Core Difference

A mortgage broker has access to mortgages from many lenders — typically 20–40+ banks, credit unions, monolines, and alternative lenders. When you work with a broker, they shop your scenario across that network and bring you the best available option.

A bank's mortgage specialist works for one lender only. They can offer you what their employer offers, and nothing else. They cannot tell you that the lender down the street has a lower rate today.

Neither option is universally better. The right choice depends on your financial situation, the complexity of your deal, and how much time you want to spend shopping.

Access to Lenders: The Broker Advantage

Canada has over 40 mortgage lenders offering products to residential borrowers: the Big 6 banks (RBC, TD, BMO, Scotiabank, CIBC, National Bank), over a dozen monoline lenders (who do nothing but mortgages), credit unions, B-lenders, and private lenders.

The Big 6 banks have their own broker channels where they offer rates to mortgage brokers — often at slightly better pricing than their branch rates, because the broker brings volume.

For most borrowers, a mortgage broker has access to more options at better prices than walking into any single bank branch. The benefit of this access increases with the complexity of your situation: • If you are salaried with strong credit buying a standard property: a broker's advantage over your existing bank is moderate — you will likely find a good rate either way • If you are self-employed, have imperfect credit, are buying a non-standard property, or have a complex income situation: the broker's access to specialized lenders becomes essential

Rates: Who Gets You the Better Deal?

Mortgage brokers typically access wholesale or broker-channel rates that are the same as or better than posted branch rates. The reason: lenders prefer paying a broker a finder's fee over the cost of operating branch networks.

However, banks sometimes offer loyalty discounts to existing customers — especially if you have multiple products (chequing, savings, investments) with them. These relationship discounts can occasionally match or beat broker rates.

The honest answer: you will not know which is better until you get quotes from both. Getting a broker quote and a bank quote in parallel is the best way to ensure you are not leaving money on the table.

A few basis points matter. On a $600,000 mortgage at 25 years: • 0.10% lower rate = roughly $6,000 saved over the first 5-year term • 0.25% lower rate = roughly $15,000 saved over the first 5-year term

When a Mortgage Broker Has the Edge

A mortgage broker is generally the better choice when:

• You are self-employed or have irregular income. Banks apply strict guidelines for self-employed borrowers. Brokers have access to B-lenders who use stated income programs or alternative qualification methods.

• Your credit score is below 680. Most major banks prefer 680+. Brokers have access to B-lenders and credit unions with more flexible credit requirements.

• You are buying a non-standard property. Condos under 500 sq ft, rural properties, mixed-use buildings, unique properties — banks often decline or restrict LTV. Specialty lenders in a broker's network handle these regularly.

• You are a newcomer to Canada. Many banks want 2+ years of Canadian credit history. Specialist brokers know lenders with newcomer programs.

• You are consolidating debt or doing a complex refinance. Brokers can model the scenario across multiple lenders and find the best structure.

• You want maximum rate shopping. A broker compares 30+ lenders at once; you would need to visit 30+ branches to do this yourself.

When Going Directly to Your Bank Makes Sense

A direct bank approach can work well when:

• You have a strong existing relationship. If you have held investments, business banking, or significant deposits at a bank, their relationship pricing may match or beat what a broker finds. Ask your bank specifically about loyalty discounts.

• Your deal is completely straightforward. Salaried employment, excellent credit (720+), large down payment, standard property. In this scenario, your bank will likely approve you easily and the rate competition will be tight regardless.

• You want one banking relationship. Some borrowers prefer dealing with one institution for all their financial products. This is a legitimate preference, though it may cost marginally more.

• Speed is critical. In a hot market, some buyers prefer a direct bank approval because it is a name the seller recognizes. Though a broker can arrange the same speed.

The Conflict of Interest Question

A common concern: "Is my bank advisor on my side?" The honest answer is no — your bank's mortgage specialist is an employee of the lender. Their job is to sell you their employer's products. They are not legally required to tell you that the bank down the street has a better rate today.

A mortgage broker, by contrast, is legally required (in most provinces) to act in the borrower's best interest and present options from their lender network. However, brokers have their own conflicts of interest: volume bonuses from certain lenders, relationships with preferred BDMs, or incentives to favor lenders who pay them higher finder's fees.

Neither party is perfectly conflict-free. The practical mitigation: get quotes from at least two sources (a broker and your own bank), and ask your broker to show you multiple lender options, not just one.

The Recommendation: Use a Broker First, Then Check Your Bank

For most Canadians, the process that finds the best outcome:

1. Get quotes from a mortgage broker — they do the multi-lender shopping for you at no cost 2. Take the best broker quote to your bank and ask: "Can you match or beat this?" 3. If your bank beats the broker rate AND the terms are comparable, go with your bank 4. If the broker rate is equal or better, go with the broker

This process takes less time than most people expect. A broker can have preliminary options in front of you within a day. Your bank appointment might take 45–60 minutes. The total time investment for this comparison is 2–3 hours and can save you thousands of dollars.

One important caveat: rate is not everything. Compare the full mortgage: prepayment privileges, penalty calculation method (IRD vs 3-month interest), portability, and whether it is a collateral or conventional charge. A broker can explain these differences across the lenders they are comparing.
