Renewal Mistakes, Complaints and Official Sources
Collateral charge mortgages: why switching at renewal can cost more
How standard and collateral mortgage charges differ in Canada, why a collateral charge or readvanceable mortgage can make switching at renewal costlier, and how to price the move.
A standard charge registers your mortgage on title for the amount you borrowed. A collateral charge registers it for a higher amount, sometimes up to or above the home's value, so the lender can lend you more later, such as a home equity line of credit, without a new registration. The catch at renewal: many lenders cannot take over another lender's collateral charge, so switching usually means discharging the old charge and registering a new one, with legal or notary fees, and paying out any linked line of credit. It does not stop you switching, but you need to price it in before comparing rates.
This guide is part of the mortgage renewal mistakes guide. Figures are illustrative.
Standard vs collateral charge
| Feature | Standard charge | Collateral charge |
|---|---|---|
| Amount registered on title | The mortgage amount | Often more than the mortgage, up to or above the home's value |
| What it secures | The mortgage | The mortgage and other borrowing with that lender, depending on the terms |
| Borrowing more later | Usually a new charge or refinance | Can often be done without new registration, subject to approval |
| Switching at renewal | Often a simple assignment or transfer, with low legal cost | Usually a discharge and new registration |
| Second mortgage from another lender | Easier, because less of the home's value is registered | Harder, because the first charge may cover the full value |
Readvanceable mortgages, which combine a mortgage with a line of credit that grows as you repay principal, are usually registered as collateral charges. In Quebec, the equivalent is often called a hypothèque parapluie or multiproduit; see Quebec renewal differences.
How to find out which you have
- Look at your mortgage agreement or the lawyer's or notary's reporting letter from your purchase.
- Compare the registered amount of the charge with the amount you borrowed. If the registered amount is higher, it is very likely a collateral charge.
- Check whether you have a line of credit or other products "under" the mortgage.
- Ask your lender: "Is my mortgage registered as a standard or collateral charge, and for how much?"
- A title search through your provincial land registry shows the registered charge, usually for a fee.
Worked example: does a switch still pay?
Illustrative figures: $450,000 balance at maturity, 20 years left, five-year fixed.
| Renewal with current lender | Switch to new lender | |
|---|---|---|
| Rate | 4.59% | 4.29% |
| Payment | $2,858.28 | $2,787.07 |
| Interest over 5 years | $93,968.32 | $87,654.76 |
| Balance after 5 years | $372,471.41 | $370,430.44 |
Interest saved over the term: $93,968.32 - $87,654.76 = $6,313.56.
Costs of the switch with a collateral charge, illustrative only:
- Legal fees for a new registration: $1,200
- Old lender's discharge fee: $400
- Appraisal: $0, covered by the new lender
- New lender's contribution to legal fees: -$800
Net cost: $1,200 + $400 - $800 = $800. Saving after costs: about $5,514, plus the slightly lower balance. The switch still pays on these numbers.
If there is a line of credit under the collateral charge with $25,000 owing, the switch also needs that balance paid out or moved. If the new lender puts it into the new mortgage, the balance rises to $475,000, which is no longer a straight switch: expect full qualification at the stress-test rate for an uninsured mortgage, and possibly a different rate tier. See the stress test when switching.

Ways to reduce the cost
- Ask the new lender whether it covers legal fees for collateral switches, and the cap.
- Ask whether it can accept a transfer of a collateral charge; a few lenders do in some provinces.
- Ask your current lender for the discharge fee in advance.
- Pay down a small line of credit balance before the switch so it does not inflate the new mortgage.
- Compare the full cost with what your current lender will offer once it sees the outside offer.
Is a collateral charge a bad thing?
Not necessarily. It is convenient if you plan to borrow against your home again, for renovations or investments, because you avoid new registration costs. The trade-off is less flexibility to move, especially for small balances where legal fees take a larger share of any saving. When you choose a mortgage at renewal or purchase, ask how it will be registered.
Checklist before switching a collateral mortgage
- Registered amount and type of charge confirmed
- All products under the charge listed, with balances
- Discharge fee from the current lender, in writing
- Legal or notary fees, and the new lender's contribution, in writing
- Whether the switch remains a straight switch
- Funding date set for the maturity date
- Plan for any line of credit you want to keep
If a lender charged a discharge fee or delayed a discharge in a way that does not match its disclosure, see how to complain about your mortgage lender. The bodies that regulate lawyers, notaries and land registries are listed in official sources.
Frequently asked questions
Can my lender refuse to let me switch because of a collateral charge?
No. You can pay out the mortgage at maturity and discharge the charge. The charge affects the cost and steps, not your right to leave at maturity.
Do all big banks use collateral charges?
Practices differ by lender and product, and lenders change them. Some register most mortgages as collateral charges, others only readvanceable products. Ask your lender.
Is the discharge fee regulated?
Discharge fees are set by the lender and disclosed in its fee schedule. Some provinces regulate aspects of mortgage discharge, such as timing. Check your provincial rules and your lender's disclosure.
Will a collateral charge affect my home insurance or property tax?
No. It affects the registered security, not insurance or tax.
