## TL;DR
- The Minimum Qualifying Rate (MQR) for uninsured mortgages is the greater of 5.25% or the contract rate plus 2% — borrowers must demonstrate they can afford payments at this higher rate.
- Uninsured straight switches at renewal are exempt from the prescribed MQR stress test under 2026 OSFI rules, provided the mortgage amount and amortization remain unchanged.
- Portfolio Loan-to-Income (LTI) limits now apply to federally regulated lenders, capping the share of high-LTI mortgages in their books to manage systemic risk.
- Home Equity Line of Credit (HELOC) components remain capped at a 65% Loan-to-Value (LTV) limit for all federally regulated institutions under OSFI Guideline B-20.

## Canada's 2026 Mortgage Stress Test Explained: Switches, MQR Rates & Qualification Rules
This guide explains how Canadian banks — known as Federally Regulated Financial Institutions (FRFIs) — determine your ability to handle mortgage payments, as governed by the Office of the Superintendent of Financial Institutions (OSFI). A key update now simplifies straight switches at renewal: if you're moving your uninsured mortgage to a new lender without changing the amount or amortization, you may be exempt from the full Minimum Qualifying Rate (MQR) stress test. This means more Canadians can shop for better rates at renewal without the added hurdle of requalifying at a higher stress-test rate.

- Switching your uninsured mortgage to a new lender at renewal may now be exempt from the MQR stress test — meaning you could qualify for a better rate without requalifying at the full stress-test threshold.
- The Minimum Qualifying Rate (MQR) is currently the greater of 5.25% or your contract rate plus 2% — knowing this number helps you understand exactly what income and debt levels you need to qualify.
- Straight switches (same mortgage amount, same amortization, new lender) are now simpler under 2026 OSFI rules, potentially saving you legal fees and reducing paperwork at renewal.
- With a lower rate secured through a straight switch, you may reduce your monthly mortgage payments — freeing up hundreds of dollars each month for savings, investments, or everyday expenses.

## Strategy & FAQ
The latest mortgage qualification rules — including OSFI's straight-switch exemption, portfolio Loan-to-Income (LTI) limits, and the current Minimum Qualifying Rate (MQR) of the greater of 5.25% or contract rate plus 2% — can be complex to navigate. Here are answers to the most common questions to help you advise clients effectively.

### What is an 'uninsured straight switch' and how does it benefit you?
Under the OSFI B-20 amendment (effective late 2024), an 'uninsured straight switch' lets you transfer your existing mortgage to a new lender without the stress test:

| Condition | Requirement |
|---|---|
| **Loan amount** | Cannot increase (max +$3,000 for fees) |
| **Amortization** | Cannot extend beyond original schedule |
| **Payment schedule** | Can change (e.g., monthly to bi-weekly) |
| **Lender type** | Must be a federally regulated institution (FRFI) |
| **Property** | Same property — no portability to new home |

This change gives borrowers real leverage to shop for better rates at renewal without stress-test barriers.

- You can only skip the mortgage stress test when switching lenders if you already have a down payment of 20% or more.
- To qualify, you need to keep your mortgage amount and payment schedule the same when you renew.
- Lenders will still check to make sure you can comfortably afford your mortgage payments.
- They'll look at your income, debts, and credit score to ensure you can handle your mortgage, even if interest rates rise.
- These rules help protect the financial system while still allowing you to shop around for the best mortgage interest rate at renewal.

### Will you still need to pass a 'stress test' when switching lenders?
Here's when the stress test applies and when it doesn't in 2026:

| Transaction Type | Stress Test? | Qualifying Rate |
|---|---|---|
| **New purchase** | ✅ Yes | Higher of contract+2% or benchmark |
| **Refinance** | ✅ Yes | Higher of contract+2% or benchmark |
| **Renewal (same lender)** | ❌ No | Contract rate only |
| **Straight switch (new lender)** | ❌ No | Contract rate only |
| **Increasing mortgage amount** | ✅ Yes | On the incremental amount |
| **Extending amortization** | ✅ Yes | Full re-qualification |

- Lenders will check your financial history and ability to repay your mortgage.
- Lenders will look at your income and debts to make sure you can comfortably afford your mortgage payments.
- Lenders have to follow rules and keep records about how they approve mortgages.
- When you get a mortgage without a big down payment, lenders use a 'stress test' with a higher interest rate to see if you can still afford your payments if interest rates rise.

### What is a Loan-to-Income (LTI) limit, and how might it impact future mortgage lending?
LTI limits are applied to a *bank's entire mortgage portfolio*, not individual borrowers, and aim to reduce risks from high household debt levels.

- Loan-to-income limits won't directly affect whether you get approved for a mortgage.
- Banks are expected to start using loan-to-income limits in early 2025.
- Regulators will monitor how well these new loan-to-income limits are working.
- Once the loan-to-income system is running smoothly, regulators will decide if the mortgage stress test is still needed for mortgages with a large down payment.

### How does OSFI ensure banks are following these guidelines?
OSFI monitors banks to ensure they are financially sound and comply with regulations; If a bank doesn't manage mortgage risks properly, OSFI can take action, such as increasing capital requirements.

- Your bank needs a solid plan for approving mortgages that fits how much risk they're willing to take.
- Banks should be extra careful when dealing with riskier mortgages, keeping a close eye on them.
- Banks need to have enough money set aside to cover potential losses from their mortgages.
- The government can make banks fix any problems to keep the financial system safe and encourage them to manage risk well.
