Switching Mortgage Lenders at Renewal in Canada: 2026 Straight-Switch Guide (No Stress Test)
Switch lenders at renewal without the prescribed MQR when the file stays a straight switch.
TL;DR
Credit unions are not FRFIs. Confirm the receiving lender is federally regulated before assuming the OSFI exemption applies.
High-ratio insurance transfer is a different path — do not flatten it into always tested. Portfolio-insured / low-ratio switches have been exempt since Finance 16 December 2024; UPB may rise by at most $3,000 for costs; no equity take-out.
Guideline B-20 / lender overlays can still apply even when the prescribed MQR does not. Ask the receiving lender in writing before you apply.
This OSFI exemption only applies to federally regulated financial institutions (FRFIs). Credit unions are not FRFIs. Confirm the receiving lender's regulatory status before assuming you qualify.

Expert Research FAQ
What exactly is a 'straight switch' mortgage renewal, and how does it impact you?
A 'straight switch' means moving your current uninsured mortgage to a new lender without changing the amount you borrow or how long you have to pay it back.
The OSFI exemption is for an uninsured mortgage switching between federally regulated lenders. Credit unions are not FRFIs. Portfolio-insured low-ratio switches follow Finance's 16 December 2024 parallel.
Even if you qualify for a straight switch, the new lender will still check to make sure you can afford your mortgage payments.
Lenders will look at your history of paying debts on time to decide if you qualify for a mortgage renewal.
When setting interest rates, lenders consider the current and future economy, as well as their own comfort level with risk.
Even with the MQR exemption, how will FRFIs assess my client's eligibility?
This includes a careful review of their willingness and ability to pay, using conservative debt service ratio calculations that account for potential future financial pressures.
Lenders must follow guidelines for responsible mortgage lending.
Lenders need to stick to these mortgage rules.
Lenders will check if you can comfortably afford your mortgage payments.
Lenders will carefully calculate if you can handle your debts, even if interest rates change.
Lenders must have strong processes to manage mortgage risk.
How do Loan-to-Income (LTI) limits factor into the straight switch process?
OSFI introduced LTI limits to reduce risks linked to high household debt levels within lenders' mortgage portfolios.
Lenders have limits on how much they can loan compared to borrowers' incomes.
These limits don't directly affect your ability to get a mortgage or switch lenders.
Lenders need to follow these rules starting in early 2025.
The government will monitor these new rules to see if they're working as intended.
These limits help protect lenders from risk related to high levels of debt.
What if my client has a Home Equity Line of Credit (HELOC) combined with their mortgage?
The HELOC portion of a mortgage should not exceed 65% of the property's value; any additional credit must be amortized like a traditional mortgage.
Lenders will check to make sure you can repay your home equity line of credit (HELOC) along with your mortgage and will monitor your credit.
Typically, you can only borrow up to 65% of your home's value as a HELOC.
You can borrow more than 65% of your home's value, but that extra amount will need to be paid off with regular mortgage payments.
Lenders manage their risk by ensuring the average loan-to-value (LTV) of their HELOCs is below their maximum stated limit.
What disclosures are required for residential mortgage portfolios, especially related to straight switches?
This includes details like the proportion of insured versus uninsured mortgages and HELOCs, broken down by geographic region.
More information from lenders helps you understand their mortgage practices.
Lenders need to share enough details about their mortgages so everyone can see how healthy their business is.
Lenders who offer mortgages must publish information about them every three months.
These reports show how many mortgages are insured, how many are not, and where the properties are located.
