What is a Trigger Rate

David Sahibzada • December 14, 2022

This is going to be the last time we’re talking about interest rates and mortgages this year. And if we’re happy about it, you’re likely ecstatic.


So, let’s get to today’s topic: what is a trigger rate and do you need to worry about it?


Brief Recap of Variable Rate Mortgages


We’ve covered this previously, but just so we’re all starting from the same page.


A variable rate mortgage means your interest rate is dependent on the Prime rate. Prime rate is the interest rate used by your lender or bank when lending to clients and is related to the Bank of Canada’s overnight lending rate.


When Bank of Canada rates go up, Prime Rates go up, and the interest you pay on your variable-rate mortgage also goes up. This interest payment can be paid in two ways:



  • Static Variable Rate Mortgage: Your monthly payment remains the same, but more of that payment goes towards interest.
  • Adjustable Rate Mortgage: Your monthly payment will increase when there is an increase in rates. Your principal payment will remain the same.


That was the shortest explanation of those two products we’ve ever done…might have to stick to that format.


Trigger Rates with Static Variable Rate Mortgage


The trigger rate is something that impacts static variable-rate mortgage holders. It’s the point at which your regular payment is no longer paying any principal; you’re just paying interest.


Definitely a ‘triggering’ situation.


When you reach this trigger rate, there’s an increase in the balance owed on your mortgage. This is because your payment is no longer enough to cover the cost of borrowing.


Any amount still owing is deferred interest to be paid at a later date.


But if you’re asking, “well, what is my trigger rate?” you’re going to have to give your trusted mortgage broker a call. Your trigger rate will be different from your neighbour’s, your cousin twice removed, and your niece who just bought her first house.


What Do You Do If You’ve Reached Your Trigger Rate?


According to a report by the Bank of Canada, “roughly half of all mortgage holders with static-payment variable-rate mortgages have already reached their trigger rate.”


Simply, you could leave your payment the way that it is, making interest-only payments until rates decrease.


But, we don’t recommend that.


You don’t want to be owing more on your mortgage, which will demand a higher interest payment down the road, even if (and when) rates come down. When this happens, you actually start to go backward on your amortization.


This is called ‘negative amortization’ and means that the principal payments are negative. Your mortgage balance increases each month in order to cover the interest cost.


Talk with your mortgage broker about how you can increase your monthly payment or change your payment schedule to make it more manageable.


Because you’re a variable-rate holder, it’s easier to break your mortgage if you need to refinance or move to a fixed-rate mortgage.


And don’t wait until you think rates will go down.


Rates are unpredictable to even those who make it their job to predict them. Reach out to a mortgage broker now if you’re coming up to your trigger rate.


We Have To Mention Trigger Point


Not to add more mud to the muddy waters, but alongside the trigger rate, there’s a trigger point.


A trigger point is when the balance on your mortgage is back at or exceeds the amount you borrowed when you first got your mortgage.


This could also be described as a percentage of your home’s value. For example, if your mortgage balance is over 100% of your home’s value, you’re at your trigger point.


Most lenders in Canada will use a trigger point of when the principal amount plus interest owing exceeds 80% of the fair market value.


When you reach this point, it’s going to trigger an action (see what we did there?)


Your lender is going to ask that you either increase your monthly payment, make a lump-sum payment, convert to a fixed rate or refinance to extend your amortization.

Mortgage Approval 101: GDS & TDS Explained

By David Sahibzada • February 17, 2026
Can You Afford That Mortgage? Let’s Talk About Debt Service Ratios One of the biggest factors lenders look at when deciding whether you qualify for a mortgage is something called your debt service ratios. It’s a financial check-up to make sure you can handle the payments—not just for your new home, but for everything else you owe as well. If you’d rather skip the math and have someone walk through this with you, that’s what I’m here for. But if you like to understand how things work behind the scenes, keep reading. We’re going to break down what these ratios are, how to calculate them, and why they matter when it comes to getting approved. What Are Debt Service Ratios? Debt service ratios measure your ability to manage your financial obligations based on your income. There are two key ratios lenders care about: Gross Debt Service (GDS) This looks at the percentage of your income that would go toward housing expenses only. 2. Total Debt Service (TDS) This includes your housing costs plus all other debt payments—car loans, credit cards, student loans, support payments, etc. How to Calculate GDS and TDS Let’s break down the formulas. GDS Formula: (P + I + T + H + Condo Fees*) ÷ Gross Monthly Income Where: P = Principal I = Interest T = Property Taxes H = Heat Condo fees are usually calculated at 50% of the total amount TDS Formula: (GDS + Monthly Debt Payments) ÷ Gross Monthly Income These ratios tell lenders if your budget is already stretched too thin—or if you’ve got room to safely take on a mortgage. How High Is Too High? Most lenders follow maximum thresholds, especially for insured (high-ratio) mortgages. As of now, those limits are typically: GDS: Max 39% TDS: Max 44% Go above those numbers and your application could be declined, regardless of how confident you feel about your ability to manage the payments. Real-World Example Let’s say you’re earning $90,000 a year, or $7,500 a month. You find a home you love, and the monthly housing costs (mortgage payment, property tax, heat) total $1,700/month. GDS = $1,700 ÷ $7,500 = 22.7% You’re well under the 39% cap—so far, so good. Now factor in your other monthly obligations: Car loan: $300 Child support: $500 Credit card/line of credit payments: $700 Total other debt = $1,500/month Now add that to the $1,700 in housing costs: TDS = $3,200 ÷ $7,500 = 42.7% Uh oh. Even though your GDS looks great, your TDS is just over the 42% limit. That could put your mortgage approval at risk—even if you’re paying similar or higher rent now. What Can You Do? In cases like this, small adjustments can make a big difference: Consolidate or restructure your debts to lower monthly payments Reallocate part of your down payment to reduce high-interest debt Add a co-applicant to increase qualifying income Wait and build savings or credit strength before applying This is where working with an experienced mortgage professional pays off. We can look at your entire financial picture and help you make strategic moves to qualify confidently. Don’t Leave It to Chance Everyone’s situation is different, and debt service ratios aren’t something you want to guess at. The earlier you start the conversation, the more time you’ll have to improve your numbers and boost your chances of approval. If you're wondering how much home you can afford—or want help analyzing your own GDS and TDS—let’s connect. I’d be happy to walk through your numbers and help you build a solid mortgage strategy.

Start Smart: Get Pre-Approved for Your Mortgage

By David Sahibzada • February 3, 2026
Thinking of Buying a Home? Here’s Why Getting Pre-Approved Is Key If you’re ready to buy a home but aren’t sure where to begin, the answer is simple: start with a pre-approval. It’s one of the most important first steps in your home-buying journey—and here's why. Why a Pre-Approval is Crucial Imagine walking into a restaurant, hungry and excited to order, but unsure if your credit card will cover the bill. It’s the same situation with buying a home. You can browse listings online all day, but until you know how much you can afford, you’re just window shopping. Getting pre-approved for a mortgage is like finding out the price range you can comfortably shop within before you start looking at homes with a real estate agent. It sets you up for success and saves you from wasting time on properties that might be out of reach. What Exactly is a Pre-Approval? A pre-approval isn’t a guarantee. It’s not a promise that a lender will give you a mortgage no matter what happens with your finances. It’s more like a preview of your financial health, giving you a clear idea of how much you can borrow, based on the information you provide at the time. Think of it as a roadmap. After going through the pre-approval process, you’ll have a much clearer picture of what you can afford and what you need to do to make the final approval process smoother. What Happens During the Pre-Approval Process? When you apply for a pre-approval, lenders will look at a few key areas: Your income Your credit history Your assets and liabilities The property you’re interested in This comprehensive review will uncover any potential hurdles that could prevent you from securing financing later on. The earlier you identify these challenges, the better. Potential Issues a Pre-Approval Can Reveal Even if you feel confident that your finances are in good shape, a pre-approval might uncover issues you didn’t expect: Recent job changes or probation periods An income that’s heavily commission-based or reliant on extra shifts Errors or collections on your credit report Lack of a well-established credit history Insufficient funds saved for a down payment Existing debt reducing your qualification amount Any other financial blind spots you might not be aware of By addressing these issues early, you give yourself the best chance of securing the mortgage you need. A pre-approval makes sure there are no surprises along the way. Pre-Approval vs. Pre-Qualification: What’s the Difference? It’s important to understand that a pre-approval is more than just a quick online estimate. Unlike pre-qualification—which can sometimes be based on limited information and calculations—a pre-approval involves a thorough review of your finances. This includes looking at your credit report, providing detailed documents, and having a conversation with a mortgage professional about your options. Why Get Pre-Approved Now? The best time to secure a pre-approval is as soon as possible. The process is free and carries no risk—it just gives you a clear path forward. It’s never too early to start, and by doing so, you’ll be in a much stronger position when you're ready to make an offer on your dream home.
