Why You Should Never Get Your Mortgage Directly from the Bank (and What to Do Instead)

Most Canadians get their first mortgage from their main bank. The reasoning is intuitive: the bank knows you, you trust them, the branch is convenient, the process feels safe. The vast majority of borrowers who follow that intuitive path overpay for their mortgage by thousands of dollars, sometimes tens of thousands, over the life of the loan.

This post explains, in concrete terms, why that happens. It is not a rant against banks. Banks are well-run businesses doing exactly what they're designed to do. The issue is that what they're designed to do is not the same as what's best for you, and the structural difference between bank lending and brokered lending produces measurably different outcomes for the borrower.

The structural difference

A bank mortgage specialist works for one institution and can offer one institution's products. Their compensation is tied to volume and profitability for their employer. If their lender's rate is 30 basis points above market, they cannot offer you the market rate. They can only offer you what their bank sells.

A mortgage broker is licensed independently and works with 50+ lenders, including the big five Canadian banks, monoline lenders, credit unions, trust companies, alternative lenders, and private lenders for specialized situations.

The broker is compensated by the lender that wins the deal, meaning the broker's incentive is to find the lender that says yes at the most competitive terms. The borrower pays no fee directly in a standard transaction.

The result is straightforward: the broker shops the market on your behalf. The bank specialist shops only their own shelf.

Rate is not the only thing that matters

Prepayment penalty calculation

If you ever break a fixed-rate mortgage mid-term, you pay an Interest Rate Differential penalty. The penalty calculation is where banks systematically charge more than monoline lenders.

The big five banks calculate IRD using posted rates, which are higher than the rates they actually lend at. The difference between posted and contract rates inflates the penalty calculation, sometimes producing penalty quotes in the five figures on mortgages of moderate size.

Monoline lenders typically calculate IRD using actual contract rates. The same mortgage broken at the same point in the term can produce a penalty that is several times smaller at a monoline than at a major bank.

Portability and assumability

If you sell your home and buy another during your mortgage term, can you take the mortgage with you? At what cost? Can a future buyer assume your low-rate mortgage if you sell? Some monoline lenders offer cleaner portability and assumability terms. These features rarely matter at signing. They matter three years in, when life shifts.

Collateral charges vs. standard charges

Several major banks register mortgages as collateral charges rather than standard charges. The practical effect: when you go to switch lenders at renewal, a collateral charge requires a full new mortgage application and new legal work, which adds friction and cost to the switch. It's not a coincidence that this structure makes you stickier.

Most monoline lenders register standard charges, which switch more cleanly at renewal.

Compounding frequency

Most Canadian mortgages compound semi-annually, but some products, especially HELOCs and some variable-rate mortgages, compound monthly or even daily. The effective rate is slightly higher with more frequent compounding. Read the disclosure, or have someone read it for you.

But my bank offered me a great rate

Compared to what? A rate is great only relative to the alternatives. If the alternative is the same bank's posted rate, almost any negotiated discount looks great. If the alternative is the broker market, the bank's great rate is often 15-40 basis points above what's available elsewhere. On a $500,000 mortgage, 25 basis points compounds to roughly $6,000 over a five-year term.

The rate is one variable. A 4.79% rate at a bank with a five-figure IRD penalty calculation may be worse than a 4.89% rate at a monoline with a thousand-dollar IRD penalty calculation, depending on the likelihood you'll break the mortgage.

When the bank actually wins

• Existing relationship and bundled products. If you have multiple accounts, investments, and lines of credit at the bank, the relationship discount may be meaningful.
• A genuinely competitive offer. If your bank specialist comes back with a rate that matches the broker market and features that match monoline standards, take it.
• Specialized products. Some banks have unique product features, such as specific HELOC structures, foreign income programs, or high net worth programs.
• Same-week closings. Banks with existing client relationships can sometimes move faster on tight closings than a new broker engagement.

The shared thread: the bank wins when there's a specific, identifiable reason, not when it's the default option.

How to actually shop

1. Get a written quote from your bank. Not around 4.99%, but a specific rate, with a 90-day rate hold, on a specific product, in writing.
2. Get a written quote from a broker with the same parameters: specific rate, term, and product features.
3. Compare more than just the rate. Ask about prepayment penalties, portability, prepayment privileges, and collateral vs. standard charge.
4. If the bank is competitive, take the bank. If the broker is competitive, take the broker.

This takes a couple of hours of effort and saves multiple thousands of dollars. The hourly rate on this work is among the highest of any task you'll perform in your financial life.

What a broker should actually do for you

• Pull offers from multiple lenders and present the realistic short list, not every lender.
• Explain the trade-offs in plain language.
• Manage document collection and submission.
• Coordinate with your real estate lawyer, realtor, and accountant where relevant.
• Stay in touch through the term and reach out before renewal.

If your broker is not doing those things, find a different broker. The market is large, the standards vary, and good brokers exist in every major Canadian market.

Next step

If you're within 12 months of a mortgage decision, purchase, renewal, or refinance, start a no-obligation broker review. We'll pull comparable offers from our lender network and lay them out alongside whatever your bank has quoted you, so you can see the actual difference in writing.

If your bank comes out on top, we'll tell you. If we come out on top, you'll have saved yourself somewhere between four and five figures. Either way, you'll have made a decision based on comparison instead of inertia, which is the whole point.
