Behind on Your Mortgage in Ontario? What Sarnia Homeowners Need to Know
How power of sale really works, how much time you have, and every option you have before it gets that far.
Most people who fall behind on their mortgage in Ontario do not lose their house. The ones who do usually have one thing in common: they waited too long to talk to anyone.
If you’re a Sarnia-Lambton homeowner who has missed a payment, or you can see it coming after a renewal, a job change, or a separation, this guide is for you. You’ll learn what actually happens in Ontario (it’s usually not foreclosure), how fast the clock moves, and the realistic options you have, from easiest to hardest. No judgment. No sales pitch.
The part nobody talks about
Before the process, let’s talk about how this feels. For a lot of people, falling behind on the house is deeply embarrassing. Some feel like they’ve failed as a parent or a provider. Others worry the neighbours, family, or people at work will find out.
So they do the natural thing. They stop opening the mail, let the bank’s calls go to voicemail, and hope next month fixes it. That’s human. It’s also the single most expensive choice you can make.
Falling behind doesn’t make you a failure. It means something hit you: a renewal at a much higher rate, a layoff, a divorce, an illness. In Sarnia, it’s often the gap between contracts. Shutdown and turnaround work at the plants can pay well for a stretch and then stop. That’s a cash-flow problem, not a character flaw.
The embarrassment of one phone call now is nothing compared to a sale sign on your lawn that you didn’t choose.
You’re not alone: the numbers
Mortgage arrears are rising across Canada, and Ontario is leading the way. Desjardins reported in July 2026 that Ontario has gone from the lowest arrears rate in the country to above the national average. The main driver is renewal shock: homeowners who locked in at pandemic-era rates are now renewing at much higher payments.

Read those last two numbers again. Tens of thousands of Ontario households fell behind, and only a small fraction ended up in a forced sale. Most people find a way through. The goal of this guide is to make sure you’re one of them.
Lenders track renewals closely. If your renewal letter shows a payment you already know you can’t make, that is the moment to call, before the first missed payment, not after the third.
Foreclosure vs. power of sale in Ontario
You may have searched “foreclosure” to find this page. In Ontario, that’s usually not what happens. Foreclosure is a court process where the lender takes ownership of your home. It’s common in BC and Alberta but rare here.
Ontario lenders almost always use power of sale. The lender doesn’t take your house. It sells it, pays off the mortgage and its costs, and any money left over typically goes to you.
| Power of sale | Foreclosure | |
|---|---|---|
| How common in Ontario | The standard remedy | Rare |
| Court required? | No, it’s a right in the mortgage contract | Yes |
| Who ends up owning the home | A new buyer | The lender |
| Leftover equity | Typically paid to you after debt and costs | Typically kept by the lender |
The catch is “after costs.” Legal fees, lender charges, commission, and a lower pressured sale price all come out of your equity.
How the timeline generally works
- You miss a payment. Calls and letters from your lender start.
- The default period runs. A contractual power of sale can begin after about 15 days of continued default. A statutory one typically requires about three months. Your mortgage terms decide which applies.
- A Notice of Sale arrives. It gives you 35 days to bring the mortgage current.
- The lender lists and sells if nothing is resolved.
You can stop the process at many points along the way. But every week costs more and leaves fewer options.
If you’ve received a Notice of Sale or any formal letter from a lawyer, call a real estate lawyer the same day. The deadlines are real, and your lawyer can tell you exactly what your contract allows.
Why waiting is the most expensive option
Waiting feels free. It isn’t. Here’s what the clock actually costs you.
- The fees are yours. The lender’s legal and enforcement costs are passed on to the homeowner and come out of your equity.
- A lender-run sale is a pressured sale. Buyers see “power of sale” on a listing and expect a deal. The lender wants its money back, not top dollar for you.
- Credit damage lasts. A completed power of sale is reported as a mortgage default, which can significantly drop your score and stay on your file for years. That follows you to your next rental, car loan, or mortgage.
- Options disappear. At 30 days late, you have plenty of choices. At a Notice of Sale, you have a few. After the sale, you have none.
Picture a family whose renewal pushed their payment up a few hundred dollars a month, right as one income dropped. If they call their lender and an advisor at month one, they’re talking about restructuring. If they wait until a Notice of Sale, they’re talking about deadlines and legal bills. Same house, same family, very different outcome.
Your options, from easiest to hardest
Most people think there are only two outcomes: pay or lose the house. In reality, you likely have five or six moves. Here they are, starting with the least drastic.
- Call your lender first. Lenders would much rather work something out than run a sale. Ask directly what they offer. That might include a payment deferral, a longer amortization, adding arrears to the balance, or a temporary arrangement. Options vary by lender.
- Talk to a mortgage broker. A refinance, a debt consolidation, or a different lender may lower your payment. A broker can see options your current bank won’t offer.
- Get a full-picture budget review. A non-profit credit counsellor can help when credit cards, car loans, and the mortgage are all squeezing at once.
- Make the house earn money. A spare room or legal secondary unit can be real income here. Lambton College students and Bluewater Health staff create steady rental demand. Check zoning and the rules first; our guide to adding a basement apartment in Sarnia covers the basics.
- Sell on your own terms. If the numbers don’t work long-term, selling before the lender does keeps you in control of price, timing, and presentation. A properly marketed sale almost always beats a pressured power-of-sale listing.
- Get formal debt help. If the problem is bigger than the house, a Licensed Insolvency Trustee can walk you through consumer proposals and other options. It’s a legitimate tool, not a last-resort shame move.
Before you call anyone, write down three numbers: how much you’re behind, your monthly payment, and roughly what your home is worth. Every advisor will ask, and having them ready makes every conversation faster and more useful.
Does talking to a realtor mean selling?
No. This is the main reason people put off calling, so let’s be clear: a conversation with a realtor is not a commitment to list your house.
When someone in this situation calls Blue Coast Realty, here’s what the first conversation actually covers:
- What your home is realistically worth today, so you know your real equity and your real options.
- Whether keeping it, renting part of it, or selling makes the most sense for your numbers.
- Who else you should talk to, whether that’s a real estate lawyer, a mortgage broker, or a credit counsellor. We deal with this regularly and can point you to the right people.
It’s confidential. Nobody on your street finds out because you made a phone call. Sometimes the best advice is “don’t sell, here’s who to call,” and that’s a good outcome too. If selling is the right move, it happens on your timeline, priced and marketed properly. Our guide to pricing your Sarnia home explains how we approach it.
The bank doesn’t want your house. It wants its money. That’s your leverage, and it shrinks every week you stay quiet.
Do these three things this week
- Open the mail. Know exactly how far behind you are and whether any deadlines have been set.
- Call your lender before they call you. Ask what options they offer.
- Get your numbers. Find out what your home is worth, and talk to a lawyer if you’ve received any formal notice.
Frequently asked questions
How many missed payments before power of sale in Ontario?
It depends on your mortgage. A contractual power of sale can begin after about 15 days of continued default, while a statutory one typically requires about three months. Once a Notice of Sale is served, you generally have 35 days to bring the mortgage current.
What is the difference between foreclosure and power of sale?
With foreclosure, a court gives the lender ownership of your home. With power of sale, the lender sells the home to a new buyer and any leftover money after the debt and costs typically goes to you. Ontario lenders almost always use power of sale.
Can I stop a power of sale once it has started?
Often, yes. Paying the arrears and costs within the notice period, refinancing, or selling the home yourself can stop it. Speak with a real estate lawyer immediately about your specific deadlines.
Should I sell my house before the bank does?
If the numbers don’t work long-term, selling on your own terms usually protects more of your equity and your credit than a lender-run sale. But it isn’t the only option, so explore your lender, a mortgage broker, and a credit counsellor first.
Will talking to a realtor commit me to selling?
No. A realtor can tell you what your home is worth and help you weigh your options. Whether you list is entirely your decision.
Talk it through, confidentially
Whether you keep the house or sell on your terms, knowing your numbers is the first step. No pressure, no obligation.
