Co-Signing a Mortgage in Canada: Pros, Cons & What to Expect

Thinking about co-signing a mortgage? On the surface, it might seem like a simple way to help someone you care about achieve homeownership. But before you sign on the dotted line, it’s important to understand exactly what co-signing means—for them and for you.


You’re Fully Responsible

When you co-sign, your name is on the mortgage—and that makes you just as responsible as the primary borrower. If payments are missed, the lender won’t only go after them; they’ll come after you too. Missed payments or default can damage your credit score and put your financial health at risk.


That’s why trust is key. If you’re going to co-sign, make sure you have a clear picture of the borrower’s ability to manage payments—and consider monitoring the account to protect yourself.


You’re Committed Until They Can Stand Alone

Co-signing isn’t temporary by default. Even once the initial mortgage term ends, you won’t automatically be removed. The borrower has to re-qualify on their own, and only then can your name be taken off. If they don’t qualify, you stay on the mortgage for another term.


Before agreeing, talk openly about expectations: How long might you be on the mortgage? What’s the plan for eventually removing you? Having these conversations upfront prevents surprises later.


It Affects Your Own Borrowing Power

When lenders calculate your debt service ratios, the co-signed mortgage counts as your debt—even if you never make a payment on it. This could reduce how much you’re able to borrow in the future, whether it’s for your own home, an investment property, or even refinancing.

If you see another mortgage in your future, you’ll want to consider how co-signing could limit your options.


The Upside: Helping Someone Get Ahead

On the positive side, co-signing can be life-changing for the borrower. You could be helping a family member or friend buy their first home, start building equity, or take an important step forward financially. If handled with clear expectations and trust, it can be a meaningful way to support someone you care about.


The Bottom Line

Co-signing a mortgage comes with both risks and rewards. It’s not a decision to take lightly, but with careful planning, transparency, and professional advice, it can be done responsibly.


If you’re considering co-signing—or want to explore safer alternatives—let’s connect. I’d be happy to walk you through what to expect and help you decide if it’s the right move for you.

Fell Behind on a Payment? Don’t Panic—Here’s What to Do

By Jeff Johnson • August 12, 2026
Missed a Credit Card or Line of Credit Payment? Here’s What to Do If you’ve missed a payment on a credit card or line of credit and you’re worried about how it might affect your credit—or your future mortgage—this is for you. First things first: 👉 If you currently have an overdue balance, log in and make the minimum payment now. Seriously. Do that first. Everything else can wait. If You’re Only a Few Days Late Here’s the good news: Credit bureaus don’t record late payments until they reach 30 days past due. So if you missed a due date by a few days and paid it as soon as you noticed, it typically won’t show up on your credit report as a late payment—as long as you’re under the 30-day mark. That said, it never hurts to double-check. You can call your credit card company, explain what happened, and confirm the account is back in good standing. If you normally pay on time, they may even reverse the interest charged. It doesn’t hurt to ask. If You’re 30, 60, or 90 Days Behind If payments have gone past 30 days, your credit has likely been impacted—but the situation is still fixable. The most important step is to: Bring all accounts current as soon as possible Make at least the minimum payment on every account The faster you catch up, the more you limit the damage. Ignoring missed payments only makes things worse. If Cash Flow Is Tight If you’re struggling to make payments, communication matters. Contact your lender and keep them informed—even if you can’t pay right away. Lenders are far more willing to work with you when you’re transparent. What hurts your credit most is silence . If lenders don’t hear from you after repeated missed payments, they may write the balance off as bad debt and send it to collections. Collections can significantly impact your credit and stay on your report for years. How This Affects Mortgage Qualification Repeated missed payments can make qualifying for a mortgage more difficult—but timing matters. Once you’re back to making regular, on-time payments: Your credit can improve over time The impact of past mistakes becomes less significant If you’re planning to buy a home in the next couple of years, addressing credit issues early gives you far more options later. Final Thoughts Missing a payment doesn’t mean you’re “bad with money,” and it doesn’t mean homeownership is off the table. What matters most is how quickly you respond and how consistent you are going forward . If you’d like help reviewing your credit report or understanding where you stand from a mortgage perspective, feel free to connect. I’d be happy to walk through it with you and help you create a clear path forward.

What You Need to Know About Porting a Mortgage When Moving

By Jeff Johnson • August 5, 2026
Porting Your Mortgage: What You Need to Know Before You Rely on It Porting a mortgage means transferring your existing interest rate, remaining term, and outstanding balance from your current home to a new one when you sell and buy again. While some lenders—especially big banks—make porting sound simple, the reality is that porting a mortgage is often complex and far from guaranteed . It’s not a magic solution, and it doesn’t mean you automatically get to keep your old mortgage on your new home. In many ways, porting a mortgage feels like applying for a brand-new one—often with more conditions . Here’s why. 1. You Still Have to Re-Qualify Even though you already have the mortgage, the lender will reassess you. If you: Changed jobs Moved to a new city Are on probation Switched industries or income types …the lender may decline the port. Your previous approval does not carry over automatically. 2. The New Property Must Be Approved The lender also reassesses the new property . Just because they accepted your previous home as collateral doesn’t mean they’ll approve the next one. Expect: A new appraisal A review of the property’s condition Scrutiny around marketability and value If the lender isn’t comfortable with the property, the port can fail. 3. Property Values Rarely Line Up Perfectly Most moves involve a price difference. Buying a more expensive home: You’ll likely need additional funds at a blended rate, which can increase your payment. Buying a less expensive home: You may face a penalty for reducing the mortgage balance. Either scenario can affect your costs. 4. You Still Need a Down Payment Porting doesn’t mean you “swap houses” without cash. You still need: A down payment on the new purchase Closing costs Funds available at the right time This often surprises buyers. 5. Penalties Usually Still Apply (At First) Most lenders: Charge the full mortgage penalty when you sell Refund it only after the port is successfully completed If you’re relying on sale proceeds for your down payment, this temporary penalty can create a cash-flow issue. 6. Timelines Rarely Line Up Perfectly Real estate markets don’t cooperate. You might: Sell quickly but struggle to buy Find a home quickly but wait months to sell Closing dates rarely align, which complicates porting even further. 7. Port Periods Vary by Lender This is where the fine print matters. Depending on the lender, the port window may be: Same day only 30 days 90 days Up to 6 months If the port window is short, both transactions must close within that timeframe—or the port fails. Longer port periods offer flexibility, but also carry the risk of selling first and not finding a replacement property in time. The Bottom Line Porting your mortgage can make sense—especially if you have a strong rate and are buying a similar-priced home. But it is not guaranteed , and it comes with conditions, risks, and timing challenges. Portability is a feature, not a promise. Before you rely on it, it’s important to review all your options , including whether staying with your lender actually makes financial sense. If you’re planning to sell and buy, I’d be happy to walk you through the process, explain your options clearly, and help you decide whether porting is the right move—or if another strategy makes more sense.
