A monoline lender does one thing: mortgages. It has no branches, no chequing accounts and no credit cards, and it reaches borrowers through mortgage brokers. The big banks offer mortgages as one product among many and sell them through branches, their own mortgage specialists and online; the wider choice between a broker, a bank and an online platform is compared in the digital mortgage comparison. This page explains what monolines are, lists the main ones, and compares the two on rate, penalties, prepayment privileges, products and service. It is part of our guides to choosing a lender or broker.
What a monoline lender is
CMHC defines a mortgage finance corporation, the formal name for a monoline, as “a non-bank mortgage lender type that only offers mortgage loan products (that is, they are non-depository) and are usually only accessible via brokerages.” Because monolines don’t take deposits, they fund their loans by selling them to investors, largely through CMHC’s securitization programs; CMHC notes that mortgage finance companies “rely on CMHC securitization programs and therefore operate according to CMHC standards.”
| Big banks | Monoline lenders | |
|---|---|---|
| Products | Mortgages plus chequing, savings, cards, investments and insurance | Mortgages only |
| How you apply | Branch, the bank’s mortgage specialist, phone or online | A mortgage broker; a few through an online platform |
| Deposits | Takes deposits (CDIC member) | Takes no deposits |
| Funding | Deposits, bonds and securitization | Securitization and sales to institutional investors |
| Branches | Yes | None |
| Revenue model | Cross-sells other products to mortgage clients | Earns its margin on the mortgage itself |
The big banks are covered one by one in the roundup of the best mortgage lenders in Canada, and the full range of lender types, from banks to private lenders, is laid out in the overview of types of mortgage lenders.

Monoline mortgages are prime (A-lender) products. Lenders that serve borrowers outside bank criteria, such as trust companies, are B-lenders and are compared in the B-lender roundup.
Why monoline rates are often lower
The rate gap comes from how the two business models are built:
- No branches. A monoline doesn’t carry the rent, staff and systems of a branch network.
- No cross-selling. A bank can accept a thinner mortgage margin because it expects to earn on chequing, cards and investments; a monoline has to win on the mortgage alone, so its rate and terms are what it competes on.
- Securitization funding. Selling insured mortgages into CMHC’s programs gives monolines access to low-cost funding.
- Broker distribution. Monolines pay brokers for each funded mortgage instead of running retail sales teams. How that compensation works is explained in how mortgage brokers get paid.
Banks start from a published posted rate and discount from it, and a borrower who asks often gets a lower offer; the tactics for that are in negotiating your mortgage rate. Rates change weekly, so they aren’t listed here: the current mortgage rates page compares lenders and terms.
What a rate gap is worth
On a $400,000 mortgage with a 25-year amortization, compare a bank rate of 4.99% with a monoline rate of 4.59% (illustrative rates, not quotes):
| Bank at 4.99% | Monoline at 4.59% | Difference | |
|---|---|---|---|
| Monthly payment | $2,324 | $2,234 | $90 |
| Interest paid over 5 years | $93,423 | $85,744 | $7,679 |
| Balance after 5 years | $353,974 | $351,707 | $2,268 |
Payments use semi-annual compounding, the convention for Canadian fixed-rate mortgages. The lower rate saves interest and leaves a smaller balance at renewal.
Penalties: the method varies by lender
Breaking a fixed-rate mortgage early, to sell, refinance or move to a lower rate, costs a prepayment penalty at either kind of lender. The rule is the same:
Breaking a closed mortgage, paying it off early or prepaying more than your privileges allow usually costs the higher of 3 months' interest and the interest rate differential (IRD) on a fixed rate, and typically 3 months' interest on a variable rate; your mortgage contract sets the exact method and comparison rate, and a federally regulated lender must tell you how it calculates the penalty.The difference lies in the comparison rate used for the interest rate differential (IRD). FCAC explains the choices lenders have:
The IRD is the difference between the interest left on your term at your contract rate (or the posted rate when you signed) and the interest at a second rate: the lender's current posted rate for a similar term, or that posted rate minus the discount you were originally given.Two methods are common. One takes today’s posted rate for the remaining term and subtracts the discount you received when you signed; because posted rates sit above the rates borrowers actually pay, that can give a low comparison rate and a wide differential. The other compares your rate with the rate the lender currently offers for the remaining term. A lender, bank or monoline, can use either, so the size of a penalty depends on the lender and your contract rather than on the type of lender. Your own contract states the method.
Breaking a five-year fixed mortgage with 2 years left on a $350,000 balance (illustrative rates and methods, not real lenders):
| Lender using its current offered rate | Lender using posted rate minus discount | |
|---|---|---|
| Contract rate | 4.59% | 4.99% |
| Posted 5-year rate when signed | Not used | 6.49% |
| Discount received at signing | Not used | 1.50% |
| Lender’s current rate for a 2-year term | 4.39% (offered rate) | 5.19% (posted rate) |
| Comparison rate | 4.39% | 3.69% (posted rate minus the discount) |
| Rate differential | 0.20% | 1.30% |
| Approximate IRD (differential ร balance ร years left) | $1,400 | $9,100 |
| Three months’ interest (balance ร rate รท 4) | $4,016 | $4,366 |
| Penalty (the higher of the two) | $4,016 | $9,100 |
With these assumed rates, the second method gives a penalty $5,084 higher. Other rates or terms can change the gap or reverse it. Lenders work out the IRD on the interest actually remaining, so a real quote differs from this approximation.
The exact steps, the Interest Act limit after five years and how to get a binding figure from your lender are in how mortgage penalties are calculated, and the mortgage penalty calculator runs the numbers for your balance. Variable rates work differently. On a closed variable-rate mortgage the penalty is typically 3 months' interest.
Prepayment privileges
Prepayment privileges let you pay extra each year without a penalty, usually as an annual lump sum (a percentage of the original amount) and a payment increase. They vary by lender and by product within a lender: some bank mortgages allow less than a typical monoline mortgage and some allow more, and discounted “no-frills” products at either kind of lender often cut the privileges. The per-lender figures are in the lender roundup, and how the limits work is covered in prepayment privileges.
Standard charge vs collateral charge
Most monolines register a mortgage as a standard charge for the amount borrowed, while some banks (TD and Tangerine, for example) register every mortgage as a collateral charge, which can be registered for more than you borrow so a line of credit can sit under the same charge. A standard-charge mortgage can usually be moved to a new lender at renewal by assignment, which is simpler and cheaper than the discharge and new registration a collateral charge needs. The comparison of a collateral charge vs a conventional mortgage covers the trade-off, and switching mortgage lenders explains the move itself.
Feature-by-feature comparison
| Feature | Big banks | Monoline lenders |
|---|---|---|
| Rates | Posted rates high; discounted and negotiated rates competitive | Often among the lowest for prime borrowers |
| IRD comparison rate | Varies by lender and contract | Varies by lender and contract |
| Prepayment privileges | Vary by product | Vary by product |
| Portability | Usually available | Usually available |
| HELOC or readvanceable mortgage | Widely available (for example RBC Homeline, Scotia STEP) | Limited or not offered at most monolines |
| Cash-back mortgages | Offered by several banks | Rare |
| In-person service | Branches and mortgage specialists | No branches: broker, phone and online |
| Other banking | One relationship for chequing, cards and investments | Mortgage only |
| Relationship pricing | Possible discounts for clients with other products | None: the rate is the offer |
| Renewal | Renewal letter; staying is easy | Renewal letter; staying is equally easy |
When a bank can suit better
- A home equity line of credit with the mortgage. Banks make it easy to combine a mortgage and a HELOC in a readvanceable plan, which strategies such as the Smith Manoeuvre need. Most monolines don’t offer this.
- Cash back on closing. Several banks offer cash-back mortgages that pay a percentage of the loan at closing, which can help with closing costs; the rate and repayment conditions attached to the cash are part of the comparison.
- A wider banking relationship. Clients with investments or business banking at a bank may be offered relationship pricing.
- Newcomer programs. Banks run dedicated programs for newcomers; mortgages for newcomers compares them.
- Branch service. Some borrowers want a local mortgage specialist they can meet in person.
When a monoline can suit better
- The rate is the priority. Monolines compete on rate for prime borrowers, and a broker can compare several at once.
- There is a chance of breaking the mortgage early. Selling, refinancing or a separation part-way through a term makes the penalty method matter more than a small rate difference.
- Shopping at renewal. A standard charge makes moving to another lender at renewal simpler. Renewal offers still vary, so comparing the renewal offer with the market is worthwhile; the mortgage renewal guide covers how.
- No need for branch access. Payments, prepayments and changes are handled by phone and online.
Common misconceptions
| Misconception | What actually happens |
|---|---|
| “A monoline is less safe for the borrower” | The mortgage is a registered charge with the same legal effect as a bank’s. Monolines don’t take deposits, so there are no savings at risk with them. |
| “If the lender is sold, my terms change” | A mortgage contract keeps its terms when the lender or the loan is sold; only the company you pay may change. |
| “My mortgage will be sold to someone else” | Banks and monolines both securitize mortgages; your terms don’t change. |
| “I can’t get service without a branch” | Service runs through the lender’s servicing team and your broker; most changes can be made by phone or online. |
| “The bank will match the rate, so it’s the same” | A matched rate can still come with a posted-rate IRD and different privileges, so the contract terms are worth comparing too. |
