Every Canadian mortgage bundles four separate decisions into a single conversation. Which lender actually funds the loan. Whether you go through that lender directly or through a broker. Whether the mortgage is open or closed, and what that locks you into. And whether default insurance sits on top, quietly changing your total cost either way. Most buyers walk into the process focused entirely on the interest rate they’re quoted and never touch the other three decisions at all, which is exactly how two people can end up with mortgages that look identical on paper and behave completely differently over five years.
- Who actually lends you the money
- Bank or broker, and who actually pays for it
- Open and closed mortgages change what you’re allowed to do mid-term
- Closed doesn’t mean frozen, thanks to prepayment privileges
- Porting lets you keep your rate when you move, sometimes
- The insurance that gets bundled in without you asking for it
- Pulling the whole chain together before you sign
This piece walks through the whole chain, who’s actually lending you the money, how a broker fits into that relationship, what open and closed really mean once you’re past the marketing language, and the insurance layer that gets bundled in whether you ask for it or not.
Who actually lends you the money
Canada’s mortgage market runs on a tiered system of lenders, and which tier you land in shapes your rate, your qualifying rules, and your options if your finances aren’t perfectly straightforward. A-lenders sit at the top, the Big Six banks, credit unions, and monoline lenders that only sell mortgages rather than a full suite of banking products. These lenders offer the lowest rates and the strictest qualifying rules, built around strong credit, stable documented income, and the federal stress test.
B-lenders serve borrowers who don’t fit neatly into A-lender criteria, self-employed applicants with complex income, borrowers with a bruised credit history, or anyone whose file needs a more flexible read than a Big Six underwriter is set up to give. Rates run higher here to reflect the added risk, and fees are more common, a distinction NerdWallet’s own comparison of brokers and banks touches on directly. Private lenders sit below that, typically short-term, higher-cost financing for situations that need to close fast or don’t fit any conventional box at all, a bridge rather than a long-term home.
Credit unions occupy an interesting middle position worth understanding on their own terms, since they’re provincially rather than federally regulated and sometimes offer more flexibility on qualifying than a nationally regulated bank can. If you’re in Manitoba specifically, our comparison of Winnipeg’s credit unions walks through how the local options stack up against the Big Six directly.
Bank or broker, and who actually pays for it
Going directly to a bank means working with that bank’s own mortgage specialist, who can only offer you that one institution’s products. A mortgage broker, by contrast, works across a panel of lenders that typically includes banks, credit unions, and monoline lenders, submitting your application to whichever ones best fit your specific numbers rather than steering you toward one employer’s product line.
Here’s the detail that surprises a lot of first-time buyers. On a standard prime residential mortgage, the lender pays the broker a commission once your mortgage funds, typically somewhere between 0.5 and 1.2 percent of the mortgage amount, and that commission doesn’t come out of your rate or get added to your closing costs. You’re not paying extra for the broker’s access to a wider set of lenders. The exception is B-lender or private financing, where the borrower sometimes covers part or all of a broker’s fee directly, always disclosed in writing before you sign anything. For most straightforward purchases and renewals, comparing what a mortgage broker can find against your own bank’s offer costs you nothing and can only improve your position.
Open and closed mortgages change what you’re allowed to do mid-term
A closed mortgage locks in your rate and terms for the length of the term you choose, and breaking that contract early, whether to refinance, sell without porting, or pay off more than your contract allows, triggers a prepayment penalty. This is the default structure for the vast majority of Canadian mortgages, and it earns a meaningfully lower rate in exchange for that reduced flexibility.
An open mortgage flips that trade entirely. You can pay off any amount, at any time, with zero penalty, but you pay for that freedom through a noticeably higher rate, often a few percentage points above a comparable closed product. An open mortgage makes sense in narrow situations, someone expecting to sell within months, a short-term bridge while other financing gets sorted out, or a windfall that’s about to pay the whole balance off. For anyone planning to hold the mortgage through a normal multi-year term, a closed mortgage with decent prepayment privileges built in almost always wins on total cost.
Closed doesn’t mean frozen, thanks to prepayment privileges
Most closed mortgages in Canada still let you pay down principal faster without triggering a penalty, through two separate allowances written directly into your contract. The first is an annual lump-sum privilege, commonly somewhere between 10 and 20 percent of your original mortgage amount, that you can apply toward principal once or multiple times a year depending on your lender. The second is a payment increase privilege, letting you raise your regular payment amount by a set percentage, sometimes as much as 20 percent and occasionally higher, with the extra going straight to principal.
Lenders write these as a pair of numbers in your contract, something like 15 and 15 or 20 and 20, and the two figures mean exactly what they look like, the payment-increase percentage and the lump-sum percentage side by side. Unused privilege room typically resets every calendar year rather than carrying forward, so a lump sum you didn’t use in 2026 doesn’t stack on top of your 2027 allowance. Before choosing between two otherwise similar closed mortgages, it’s worth comparing these numbers directly, since a lender offering 20 and 20 gives you real, meaningful room to accelerate payoff that a 10 and 10 product simply doesn’t.
Porting lets you keep your rate when you move, sometimes
If you sell your home and buy another one while your current term still has time left, porting lets you carry your existing rate, balance, and remaining term over to the new property instead of breaking the mortgage and starting fresh. Most fixed-rate closed mortgages from Canadian banks and credit unions are portable, but the transfer isn’t automatic. You still need to requalify under the current stress test, stay with the same lender, and complete both transactions inside a defined window, typically somewhere between 30 and 120 days depending on the lender.
Not every mortgage carries this option. Many variable-rate products and no-frills mortgage lines skip portability entirely, which is worth confirming before you sign if there’s any real chance you’ll move before your term ends. If your new home costs more than your old one, the extra amount gets financed at whatever rate is current when you port, blended together with your original rate rather than replacing it outright.
The insurance that gets bundled in without you asking for it
Two entirely different products both get called “mortgage insurance” in Canada, and mixing them up is one of the more common and costly points of confusion in the whole process. Mortgage default insurance, the CMHC, Sagen, or Canada Guaranty coverage required whenever your down payment sits under 20 percent, protects your lender if you stop paying, not you or your family. It’s mandatory at that down payment tier, its premium gets added to your mortgage balance, and our full breakdown of how CMHC insurance works covers the mechanics in depth.
Mortgage life insurance, sometimes called creditor insurance or mortgage protection insurance, is a completely different, entirely optional product that your lender will almost certainly offer at closing. If you pass away, the payout goes directly to the lender to clear the remaining mortgage balance, rather than to your family as a flexible, tax-free sum the way a standalone term life insurance policy would. It’s worth genuinely comparing the two rather than defaulting to whatever your lender hands you at the closing table, since a term life policy sized to your actual mortgage balance is frequently cheaper and gives your family control over the payout instead of the lender.
Pulling the whole chain together before you sign
Confirm which tier of lender you’re actually working with and why, since an A-lender rate quoted against a B-lender rate isn’t a fair comparison unless your file genuinely qualifies for both. Run a broker comparison alongside your own bank’s offer before committing, since it costs nothing on a standard prime file and only strengthens your negotiating position either way, and check what you’d actually qualify for using our mortgage affordability guide if you haven’t already. Compare prepayment privileges side by side with the headline rate on any closed mortgage you’re considering, whether it’s a fixed or variable product, and confirm portability directly if there’s any real chance you’ll move before the term ends. And before accepting mortgage life insurance at the closing table, price out a comparable term life policy first, using our guide to current mortgage rates and a mortgage calculator to confirm your actual balance and payment numbers going in, so every one of these four decisions gets made deliberately instead of by default.
