Canadian lenders need stronger early-warning indicators, customer segmentation and proactive debt collection management as mortgage renewals continue to test borrower affordability

No one really wants to return to the Covid pandemic period, but some of the financial decisions made during that time are still moving through the system today. In Canada, one of the clearest examples is the mortgage market.

Many borrowers who secured mortgages during the era of ultra-low rates are now renewing into a very different environment. Rates may have eased from their peak, but for many households, the increase in monthly mortgage payments is still significant. For lenders, this creates a practical and urgent question: how do you identify customers who may be heading towards difficulty before they actually miss a payment?

This is not about predicting a mortgage crisis - it is about recognising that a large part of the Canadian mortgage book is moving through a period of adjustment, and that some customers will absorb that adjustment more easily than others. That is the context in which mortgage lenders, collections leaders and portfolio management teams now need to think. The challenge is not simply who is renewing, but who is coping, who is under pressure, and who may already be showing signs of financial stress before mortgage arrears appear.

The pressure is real, even if arrears remain low

Canadian mortgage arrears remain low by historical standards. That matters, and it should not be ignored. But low arrears do not necessarily mean low customer pressure.

The Bank of Canada has estimated that around 60% of outstanding Canadian mortgages are expected to renew in 2025 or 2026. Of those renewing, around 60% are expected to see payments increase. For some borrowers, particularly those coming off five-year fixed-rate mortgages taken during the pandemic period, the increase could be materially higher than the average. That matters because mortgage stress does not always show up immediately as mortgage delinquency. Most customers will do everything they can to keep paying their mortgage - they cut back on spending, use savings, rely more heavily on credit cards, delay other payments and reduce their financial buffer.

By the time a mortgage payment is actually missed, the customer may have been under pressure for months, and this is the real challenge for lenders. The risk is not only that some customers may fall into arrears, but that lenders only identify those customers once the signs of difficulty have already become obvious.

This is a renewal issue, but it is also a collections issue

It would be easy to look at this purely as a mortgage renewal problem - a customer comes to the end of a fixed term, renews at a higher rate, their payment changes and the process moves on. However, that view is too narrow, and for many customers, renewal is not just a product event, but also an affordability event. In some cases, it may also be the moment when wider financial stress becomes visible.

A customer who looked stable three years ago may now be in a very different position. Their income may have changed, household costs may have increased, unsecured debt may have grown, savings may be lower, and their ability to absorb another increase in monthly commitments much weaker than it was when the original mortgage was agreed. That is why lenders need to connect mortgage renewal activity with early-warning analytics, affordability assessment, customer treatment and collections readiness.

The customers who need support will not all look the same. Some will simply need clear communication and a manageable renewal path. Some may need temporary support. Some may need a more detailed affordability conversation. Others may already be showing signs of wider financial difficulty, even if their mortgage account is still up to date. That is where segmentation becomes critical.

Average numbers can hide very different customer outcomes

One of the risks in any portfolio-level discussion is that averages can make the issue look more manageable than it feels for individual customers. An average payment increase may appear relatively modest, but averages are not what customers experience. A borrower in a high-cost housing market, with limited disposable income, higher unsecured debt and fewer refinancing options will experience renewal very differently from a borrower with strong income, low leverage and meaningful savings.

The same is true regionally, and stress is unlikely to be evenly spread across Canada. Higher-cost markets, weaker resale conditions and customers with less financial flexibility are likely to carry more of the pressure. For lenders, the important question is not simply how many mortgages are renewing this year. The better question is which customers face the largest payment shock, which have the least ability to absorb it, which are already showing signs of stress elsewhere, which are likely to engage early if contacted in the right way, and which may not ask for help until the problem has become more serious. These are the questions that make the difference between reactive collections and proactive customer management.

The UK experience offers a useful warning

There are clear similarities with what UK mortgage consumers have already experienced. Many UK borrowers came off very low fixed-rate deals and had to move onto significantly higher fixed rates or much higher standard variable rates. For some households, the increase was manageable. For others, it created a very real squeeze on monthly budgets.

The important point is that this did not immediately translate into a dramatic arrears crisis, but it did change customer behaviour. Customers cut back, reprioritised bills, used savings, extended mortgage terms and, in some cases, switched temporarily to interest-only arrangements. Some engaged with their lender earlier than they might have done in the past, while others waited until the pressure became much harder to manage.

The lesson for Canada is not that the same outcome will automatically happen. The markets are different. Canada has its own mortgage structure, stress-testing rules and regulatory framework, but the underlying customer behaviour is likely to be similar. When mortgage payments rise, customers do not usually move straight from “fine” to “in arrears”. There is a journey in between, and that journey is where lenders have the opportunity to intervene.

The UK experience shows that early engagement, clear communication, practical support options and good segmentation all matter. Waiting until arrears appear is too late.

Canada vs UK: the higher-rate mortgage reset

Two different mortgage markets, one similar operational challenge: identifying customer stress before it turns into arrears.

The Canadian and UK mortgage markets are structured differently, but the operational challenge is very similar. Higher rates do not hit every borrower at once. They work through gradually, which means lenders need early-warning indicators, better segmentation and proactive customer engagement rather than waiting for arrears to become the main signal.

For Canadian lenders, the renewal wave may have peaked, but the customer management challenge has not passed. In 2026, the focus needs to shift from identifying who is renewing to understanding who is coping, who is under pressure, and who may already be showing signs of stress before mortgage arrears appear.

Stress testing helps, but it does not remove the need for early warning

Canada does have important protections in place. The mortgage stress test means many borrowers were assessed against higher qualifying rates at origination, and that has helped to build resilience into the system and is one of the reasons why the current situation should not be viewed as an immediate systemic crisis. But passing a stress test at origination is not the same as being financially comfortable several years later.

Household circumstances change, cost-of-living pressure builds, unsecured borrowing increases, savings reduce, employment situations change, and family circumstances change. All of that means lenders cannot rely only on the view of affordability that existed when the mortgage was first written. They need a more current view of customer resilience, and that means looking beyond the mortgage account itself.

Rising credit card utilisation, missed non-mortgage payments, overdraft usage, reduced account balances, changes in income patterns and previous requests for support can all provide a better picture of emerging stress. The mortgage may still be up to date, but the customer may not be fine.

The operational challenge should not be underestimated

The other challenge is operational. A renewal wave does not always arrive as a sudden spike in arrears - it can arrive as increased call volumes, more complex affordability conversations, more requests for support, longer handling times and greater pressure on servicing and collections teams. At first, the pressure may sit with mortgage servicing teams, then it moves into customer support, then starts to affect early arrears, then collections teams begin to see more complex cases. If lenders wait until that point to review capacity, decisioning, customer treatment and workflow, they will already be behind the curve.

The question is not just whether lenders have enough people. It is whether those teams have the right tools, the right data and the right treatment strategies to manage customers consistently and fairly. That means being able to identify customers likely to face payment shock before renewal, prioritise contact based on risk and customer need, offer treatment options that are clear and explainable, understand when temporary support is appropriate, and track whether support strategies are actually improving customer outcomes.

It also means maintaining a clear audit trail of decisions and customer treatment. This is where collections, risk, operations and customer experience need to work together.

The wider risk picture is also changing

Mortgage renewals are not the only challenge on the horizon for Canadian financial institutions. The wider environment is becoming more complex, with interest-rate volatility, softer labour market conditions, commercial real estate exposure, funding and liquidity pressure, climate-related risk, cyber risk, fraud and regulatory change all forming part of the risk landscape.

These risks do not sit neatly in separate boxes. A weaker labour market could turn affordability pressure into arrears, house price weakness could reduce exit options for borrowers in difficulty, commercial real estate stress could increase pressure on provisions, and cyber or fraud events could create operational strain at the exact moment customers need more support. For financial institutions, the challenge is not just one specific risk, but the way different risks can interact. That makes early visibility even more important.

What should Canadian lenders do now?

There are five practical actions that should be high on the agenda:

• First, lenders need a clear view of renewal risk across the portfolio. This should include renewal date, expected payment increase, product type, region, loan-to-value, income resilience and wider customer indebtedness.
• Second, lenders should look beyond mortgage arrears as the main warning sign. By the time a mortgage payment is missed, other signs of stress may already have been visible for some time.
• Third, lenders should segment customers before they reach difficulty. Not every customer needs intervention, but the customers who do need support should be identified early.
• Fourth, lenders should make sure treatment options are consistent, explainable and measurable. It is not enough to offer support. Lenders need to know which support options are working and which may simply be delaying the problem.
• Finally, lenders should prepare their teams for more difficult and more emotional customer conversations. A higher mortgage payment is not just a financial adjustment. For many customers, it can feel stressful, personal and frightening. The tone of engagement matters.

These actions are not only about reducing arrears, but building a more responsive debt collection management operating model - one that can protect customer outcomes, improve portfolio visibility, and support fair and consistent treatment when affordability pressure rises.

The opportunity is to act before arrears become the signal

Canada’s mortgage renewal wave does not need to become a crisis. The banking system remains resilient and arrears are still low. Many borrowers have been stress-tested, and rates have eased from their peak. But none of that removes the need for action.

For lenders, the opportunity is to move earlier - to identify pressure before it turns into arrears, to use data more intelligently, to treat customers according to their actual level of risk and need, and to support collections and servicing teams with the tools they need to manage a more complex environment.

The UK experience shows that although higher-rate transitions can be managed, they are managed best when lenders act early, communicate clearly and provide practical support before customers reach the breaking point.

For Canadian lenders, the message is straightforward: do not wait for arrears to tell you which customers are struggling. By then, the real warning signs may already have been missed.
