Collateral Charge Mortgage in Canada: What It Costs You at Renewal
Switching out of a collateral charge runs $700 to $1,200 in legal work. On a $450,000 balance, a 0.05% rate gap already covers it.
October 11, 2026. The bottom line: if your mortgage is registered as a collateral charge mortgage, your bank's renewal offer is harder to walk away from than it looks. The best five-year fixed rate on the market is 4.34% today, while the best big-bank five-year fixed is 4.74% — a 40-basis-point gap (rates as of October 10, 2026). On a $450,000 balance amortized over 20 years, that gap costs you $95.35 a month, $8,426 in extra interest across a five-year term, and leaves $2,705 more owing at the end of it. That is $11,132. Breaking out of a collateral charge mortgage usually costs $700 to $1,200 in legal and registration work, so on a $450,000 balance a rate gap of roughly 0.05% already pays for the move. The charge type is not a reason to sign your renewal letter. It is a line item to price.
What a collateral charge mortgage actually is
Every mortgage in Canada is registered against your title in one of two ways.
A standard charge is registered for the exact amount you borrowed, at the exact rate and term. When the term ends, a new lender can take it over through an assignment agreement. Your title is not re-registered. The paperwork is thin and the new lender usually absorbs the cost.
A collateral charge is registered for more than you borrowed — commonly up to 125% of your property's value — and it is tied to the lender's general security agreement rather than to one loan. That is what lets a lender advance you more money later without going back to the land registry. It is the mechanism behind every readvanceable product and home equity line of credit.
The trade-off shows up at renewal. A collateral charge mortgage cannot be assigned. For a new lender to take over, the old charge has to be discharged and a new one registered from scratch. That is a full legal file, not a transfer — and it is why a collateral charge mortgage quietly raises the cost of shopping your renewal.
Nothing about this is hidden. It was disclosed when you signed. Most borrowers simply never look at it again until the renewal letter arrives.
Which lenders register a collateral charge mortgage
Whether you hold a collateral charge mortgage depends on the lender and the product, not on your credit or your down payment. The pattern across the market as of October 2026:
| Lender | Default charge type |
|---|---|
| TD Canada Trust | Collateral on all mortgages since October 18, 2010 |
| Tangerine | Collateral |
| Scotiabank | STEP is collateral; a standalone mortgage can be standard on request |
| RBC, BMO, CIBC, National Bank | Standard on a regular mortgage; collateral on readvanceable products |
| First National, MCAP, CMLS | Standard |
| Credit unions | Varies by institution and product |
Two points. A readvanceable product from any lender is a collateral charge mortgage, so a standard-charge bank does not protect you if you took the HELOC-plus-mortgage combination. And if you are unsure which you have, your mortgage commitment or a parcel register search settles it in minutes.
What it costs to leave a collateral charge mortgage
Leaving has three separate costs, and borrowers routinely confuse them.
The discharge or assignment fee is your current lender's administrative charge for preparing the payout. It appears on your payout statement. Published 2026 fee schedules compiled across the market put it in this range:
| Lender | Discharge fee |
|---|---|
| BMO | $260 |
| CIBC | $295 |
| RBC | About $300 |
| National Bank | $300 |
| TD, Scotiabank, First National, CMLS | $340 |
| MCAP | $350 |
| B-lenders (Home Trust, Equitable) | $350 to $500 |
| Large credit unions | $0 to $300, member waivers common |
The registration fee is provincial and small: $80.50 in Ontario, $77 in British Columbia, $50 in Alberta, $103 in Nova Scotia, $80 in New Brunswick.
The legal cost is where a collateral charge mortgage separates from a standard one. Discharging a collateral charge and registering a new one is lawyer or notary work, and the combined legal and registration bill typically lands between $700 and $1,200. On a standard charge the same move is often a straight assignment at little or no cost.
Before you treat that as a barrier, ask the new lender who pays it. Monoline lenders in particular frequently cover switch costs to win the file, which can take the number to zero. Also confirm whether your lender treats the move as a payout at maturity rather than an early break. If you are leaving mid-term instead of at maturity, a prepayment penalty is a separate and much larger number — our guide to what breaking your mortgage costs covers how it is calculated.
The rate gap that pays for the switch
Price the charge type against the rate, not against your patience. Using a $1,200 switching cost as a working assumption and a 20-year amortization over a five-year term, here is the rate gap at which leaving a collateral charge mortgage breaks even:
| Mortgage balance | Breakeven rate gap |
|---|---|
| $200,000 | 0.10% (10 bps) |
| $250,000 | 0.08% (8 bps) |
| $300,000 | 0.07% (7 bps) |
| $450,000 | 0.05% (5 bps) |
| $600,000 | 0.04% (4 bps) |
Those numbers are small because five years of interest on a six-figure balance dwarfs a four-figure legal bill. The gaps actually on offer today are much wider than the breakeven. At a $450,000 balance over 20 years, here is what staying at a higher rate costs over the full term, counting both extra interest and the larger balance you are left holding:
| Rate gap | Monthly difference | Five-year cost of staying |
|---|---|---|
| 0.10% | $23.69 | $2,786 |
| 0.20% | $47.47 | $5,570 |
| 0.30% | $71.36 | $8,352 |
| 0.40% | $95.35 | $11,132 |
| 0.50% | $119.44 | $13,910 |
The same 0.40% gap scales with your balance: $6,184 over five years on $250,000, $11,132 on $450,000, $16,079 on $650,000, and $21,027 on $850,000. All payment figures here are calculated on Canadian semi-annual compounding.
If your bank's answer to a switch request is an early renewal at a blended rate, read it as pricing rather than a favour. Our breakdown of blend and extend offers explains what the lender is protecting.
Where rates and the rate outlook sit today
The gap you are negotiating against is wide right now because bank renewal pricing and market pricing have drifted apart.
| Measure | Level | As of |
|---|---|---|
| Bank of Canada policy rate | 2.25% | Held September 2, 2026 |
| Prime rate | 4.45% | October 10, 2026 |
| Best five-year fixed, market | 4.34% | October 10, 2026 |
| Best five-year fixed, big bank | 4.74% | October 10, 2026 |
| Best three-year fixed | 4.34% | October 9, 2026 |
| Best five-year variable | 3.40% (prime less 1.05%) | October 10, 2026 |
| Five-year Government of Canada bond yield | 3.60% | October 8, 2026 |
| CPI inflation | 3.0% (CPI-trim 1.9%, CPI-median 2.0%) | August 2026 data |
| Unemployment rate | 6.5% | September 2026 data |
The September Labour Force Survey, released October 9, showed Canada shed 68,000 jobs and the unemployment rate rise to 6.5% from 6.4%, with average hourly wages up 2.3% year over year. After that print, market pricing put the odds of a hike at the October 28 decision near 27% and December near 88%. Treat both as market expectations that move with every data release, not as forecasts — the next CPI report lands October 19 and can reprice them.
Two things follow for a renewer. The variable discount on offer is deep: at 3.40%, a $450,000 balance over 20 years pays $2,581.27 a month against $2,798.88 on the 4.34% fixed, a $217.60 monthly difference. But that variable is priced off a prime rate that markets expect to rise, and the five-year bond yield at 3.60% is not leaving much room for fixed rates to fall. Whichever side you take, the charge-type question is the same, and so is the arithmetic on the rate gap.
What to do before your renewal date
Work backwards from maturity, and start at least 120 days out.
- Confirm your charge type in writing. Ask whether you hold a standard charge or a collateral charge mortgage, and for the registered principal amount.
- Request a written payout statement. It gives you the exact discharge fee, the balance and the maturity date, rather than an estimate.
- Get a competing quote before you respond to the renewal letter. Shop the rate first and decide on the charge second.
- Ask every competing lender one question: do you cover switch costs on a collateral charge mortgage? Get the answer before you compare rates, because a covered $1,200 changes the ranking.
- Do the arithmetic on your own balance. Multiply the balance by the rate gap for a rough annual number, then check it against the five-year table above.
- If you are staying, use the competing quote. A written offer from another lender is the only leverage that reliably moves a renewal rate.
- Secure a rate hold while you decide, so a repricing between now and maturity does not land on you.

Common questions
Does a collateral charge mortgage stop me from switching lenders?
No. It makes switching more expensive, not impossible. The old charge is discharged and a new one registered, which adds roughly $700 to $1,200 of legal and registration work compared with the near-free assignment a standard charge allows. On most balances a rate gap under 0.10% already covers that cost, and many lenders will absorb it to win your business.
Is a collateral charge mortgage ever better for me?
It can be. Because the charge is registered above your loan amount, you can usually draw additional equity later without paying to re-register your title. If you expect to borrow against your home for a renovation, a business or debt consolidation, that saves you a legal bill each time. The cost is reduced mobility at renewal. Whether that trade is worth it depends on how often you expect to access equity — and a second mortgage or a HELOC may be the cheaper route to the same cash.
Can I convert a collateral charge mortgage to a standard charge?
Generally not without a discharge and re-registration, which costs about the same as moving to a new lender. If your lender offers both charge types, the practical moment to choose is at a new registration — a switch, a refinance or a purchase — not mid-term. Ask before you sign, because once the charge is registered, changing it is a legal transaction rather than a request.

Blend and Extend in Canada: Why Your Lender's Early Renewal Offer Is a Bet on Rising Rates
Your lender's blend and extend offer is not a discount — it prices the added months at its current rate. On a $500,000 mortgage at 3.79% with 48 months left, the blend lands at 3.90%, and it only pays if the renewal rate four years out beats about 4.39%. Here is the math, the penalty you are actually avoiding, and what to ask before you sign.
