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.

RRSP Home Buyers’ Plan Explained: A Smart Way to Buy Your First Home

By Lisa Manwaring • June 24, 2026
Saving for a down payment is one of the biggest challenges first-time buyers face. What many don’t realize is that the Canadian government offers a program designed to make it easier—the Home Buyers’ Plan (HBP) . This program allows you to withdraw money from your RRSP to help purchase your first home, without immediate tax consequences. Here’s how it works: Who Qualifies? To be eligible, you generally need to be a first-time home buyer. In practical terms, this means you must not have owned a home in the past four years, nor lived in a property owned by your spouse or partner during that time. There are also special allowances if you’re living with a disability or helping a relative with a disability. In these cases, you can use the HBP even if you’ve owned a home more recently. How Much Can You Withdraw? Under the program, you can access up to $35,000 from your RRSP as an individual. Couples can combine their withdrawals for a total of $70,000 . These funds must have been in your RRSP for at least 90 days before you take them out. Paying It Back The HBP isn’t “free money”—it’s an interest-free loan from your own retirement savings. You’ll have 15 years to repay the full amount back into your RRSP, starting in the second year after withdrawal. Each year, the CRA will send you an HBP Statement of Account outlining how much needs to be repaid. If you don’t make your repayment in a given year, that amount will be added to your taxable income. Why It’s a Smart Strategy The HBP can give first-time buyers a powerful boost toward homeownership. It helps you put together a larger down payment, which can reduce your mortgage amount and monthly payments. Just remember: it’s important to balance the short-term benefit of homeownership with the long-term impact on your retirement savings. Next Steps Thinking about using the Home Buyers’ Plan? Let’s sit down and review whether it’s the right move for you. Together, we can create a strategy that gets you into your first home while keeping your future financial goals on track. 📞 Reach out anytime—it would be a pleasure to guide you through the process.

Let’s Talk About Getting Top Dollar for Your Property

By Lisa Manwaring • June 17, 2026
When it comes to selling your home, most people think the first call should be to a real estate agent. But the smartest first step often isn’t with your agent—it’s with an independent mortgage professional. Why? Because your mortgage plays a bigger role in your bottom line than most people realize. Planning to Buy After You Sell If selling means you’ll also be purchasing another property, you’ll want to know exactly where you stand financially before listing. Mortgage rules change regularly, and qualifying once doesn’t guarantee you’ll qualify again. Getting a pre-approval in place ensures you know what you can afford and eliminates surprises later. On top of that, reviewing the terms of your existing mortgage could uncover options you may not have considered. For example, porting your mortgage instead of arranging a brand-new one could save you thousands. Selling Without Buying Even if you aren’t planning to buy right away, there’s still an important step: understanding the cost of breaking your mortgage. Unless your mortgage is open, penalties apply—and they can be significant. By reviewing the numbers with a mortgage professional, you might find that simply adjusting your timeline could reduce or even avoid costly fees. Navigating Life Changes In situations like a marital breakdown, it can feel like selling the family home is the only path forward. But that’s not always the case. With the right guidance and a legal separation agreement, one spouse may be able to buy out the other, keeping the home and providing stability for everyone involved. The Bottom Line Selling your property is more than just putting a sign on the lawn—it’s about creating a financial plan that protects your equity and positions you for the best possible outcome. Before you take the leap, let’s sit down and review your options. 📞 If you’re ready to talk strategy and make sure you get top dollar for your property, I’d be happy to connect anytime.
