Should You Switch Lenders at Renewal?
What switching costs, what OSFI changed in 2024, and when staying put is the better call
Maturity is the one moment in your mortgage when leaving your lender costs you nothing in penalties. Break a mortgage mid-term and you pay three months’ interest or an interest rate differential. Move at maturity and that penalty does not exist.
That single fact is why your renewal letter deserves a competing quote before you sign it. This page covers what switching actually involves, what it costs, when it is worth doing, and the situations where staying put is the better answer.
Why Is Switching Free at Renewal?
A prepayment penalty exists because you are ending a contract early. At maturity the contract has run its course, so there is nothing to break.
What you do pay are the mechanical costs of moving the mortgage: discharging the registration with your old lender, registering with the new one, and sometimes an appraisal. Those are usually a few hundred to roughly a thousand dollars in total, and a large share of lenders cover them outright to win the business. Ask whether the lender pays switch costs before you compare rates, because a slightly higher rate with covered costs sometimes beats a slightly lower one without.
Do You Have to Pass the Stress Test Again?
This changed meaningfully in November 2024, and it is the most misunderstood part of switching.
OSFI no longer prescribes the minimum qualifying rate for uninsured straight switches at renewal (OSFI, 2024). Before that change, moving your mortgage to a new lender meant re-qualifying at the prescribed MQR, which trapped a lot of borrowers with their existing lender purely because they could not pass a test on a mortgage they had been paying reliably for five years.
To qualify as a straight switch, the transaction generally has to meet all of these:
- The loan is low-ratio, meaning a loan-to-value of 80% or less
- The mortgage was originated at a federally regulated financial institution
- You are renewing with a new lender, not your current one
- You keep your existing contractual amortization schedule
- The unpaid principal balance increases by no more than $3,000, and only to cover transaction costs
What this does not mean. It is widely reported as “no more stress test on switches,” and that is wrong in a way that gets people turned down. The new lender still assesses the application as a new origination under Guideline B-20. That means due diligence on you as a borrower, debt service ratios calculated conservatively, and qualifying rates set by that lender’s own risk appetite (OSFI, 2024).
The accurate summary: OSFI stopped mandating a specific qualifying rate for straight switches, and lenders still underwrite you. If your income has dropped or your credit has deteriorated since you first qualified, switching can still be declined.
What Counts as a Refinance Instead?
The distinction matters because it changes what you have to prove.
A straight switch moves the same balance to a new lender on the same amortization. A refinance increases the balance, extends the amortization beyond the original schedule, or pulls equity out. The moment you do any of those, you are outside the straight-switch definition and into full refinance underwriting, including the prescribed qualifying rate.
If you want to consolidate debt, fund a renovation, or access equity at renewal, that is a refinance and it should be planned as one. It is often the right move. It is simply a different transaction with different rules, and conflating the two is how people get surprised late in the process.
The Collateral Charge Complication
This is the detail that catches people, and you will not find it in your renewal letter.
Mortgages are registered against your property in one of two ways. A standard charge is registered for the amount of the mortgage and is straightforward to transfer to a new lender. A collateral charge is typically registered for more than the mortgage amount so the lender can lend you more later without re-registering.
Collateral charges are harder to move. Many lenders will not accept a transfer of one, which means discharging the existing registration and registering a brand new mortgage, with legal fees attached. That can turn a free switch into one costing several hundred to over a thousand dollars.
Ask your current lender which type you have before you assume a switch is costless. If it is a collateral charge, the switch can still be worth it on a large balance, but the math needs the extra cost in it.
What Does the Process Look Like?
| Timing | What happens |
|---|---|
| 120 days out | Get a rate hold, compare your renewal letter against market pricing |
| 90 days out | Submit the application to the new lender, provide documents |
| 60 days out | Underwriting, property valuation if required |
| 30 days out | Lawyer or title company handles discharge and new registration |
| Maturity date | New mortgage funds, old one is discharged |
Start at 120 days. A switch is not complicated, but it involves a second institution and a legal step, and compressing it into the final two weeks is how deals fall back to signing whatever the existing lender offered.
When Is Switching Not Worth It?
Being honest about this matters more than winning the file.
- Small remaining balance. On $80,000 with six years left, a 30 basis point improvement is a few dollars a month. Switch costs can exceed the saving.
- Your income or credit has changed. If you would struggle to qualify today, your existing lender renewing you without full re-underwriting is genuinely valuable. Do not risk it for a small rate improvement.
- You have a collateral charge and a modest balance. The registration cost can outweigh the gain.
- Your existing lender matches. Frequently they will, if you ask with a real competing offer in hand. That gets you the better rate with no paperwork at all.
- You are mid-life-event. Changing jobs, separating, or self-employed with a thin recent year all make a new underwrite riskier than it is worth.
The point of shopping is not to switch. It is to know what your mortgage is worth on the open market, and then decide. Sometimes the correct outcome of shopping is staying exactly where you are, at a better rate.
What Documents Will You Need?
- Recent pay stubs and a letter of employment, or two years of financial statements if self-employed
- Two years of T4s or Notices of Assessment
- Current mortgage statement showing balance, rate, and maturity date
- Property tax statement
- Proof of property insurance
- Photo identification
Self-employed borrowers should start earlier than 120 days. Income documentation takes longer to assemble and receives closer scrutiny.
Frequently Asked Questions
Is there a penalty for switching lenders at renewal?
No. Prepayment penalties apply when you break a mortgage mid-term. At maturity there is no penalty, only the mechanical costs of discharge and registration, which many lenders cover.
Do I have to pass the stress test to switch lenders?
OSFI stopped prescribing a minimum qualifying rate for uninsured straight switches in November 2024. The new lender still underwrites you under Guideline B-20 with its own qualifying standards, so switching is easier than it was but not automatic.
What is a straight switch?
Moving the same mortgage balance to a new lender while keeping your existing amortization, on a loan-to-value of 80% or less, with the balance increasing by no more than $3,000 to cover transaction costs.
How much does it cost to switch lenders?
Typically a few hundred to about a thousand dollars for discharge, registration, and any appraisal, and many lenders cover those costs. A collateral charge registration can push the cost higher.
How long does switching take?
Plan on 30 to 60 days from application to funding. Start the process 120 days before maturity so you can hold a rate while it completes.
Can I switch lenders and take out equity at the same time?
That is a refinance, not a straight switch, and it is underwritten under the full qualifying rules including the prescribed qualifying rate.
