The KPI Canadian bank data teams may be missing: Permission Elasticity

By Susan Sanei-Stamp

Canadian banks are investing heavily in smarter personalization. Better advice, more relevant offers, predictive nudges, and AI-supported experiences are quickly becoming part of the customer promise.

But there is one constraint many teams may be underestimating: permission.

Not just whether customers clicked “yes.” Not just whether consent was technically captured. The bigger question is whether customers understand what they have agreed to, and whether that permission will hold when trust is tested.

Our latest financial services research suggests that permission is not disappearing. It is thinning.

Many customers are open to data-driven personalization. At the same time, a significant share admit they do not fully understand how their financial institution uses their personal data. That creates a weaker form of consent, with friction that can surface quickly when customers feel confused, exposed, or out of control.

There is an optimistic read of the data: customers are broadly open to tailored financial experiences.

Among Canadians aged 18 to 34, 81% are comfortable with their main financial institution using personal data to offer more tailored services. Even among those aged 55 and older, comfort remains relatively strong at 70%.

But the operational read is more important: personalization is moving faster than customer comprehension.

Only 43% of 18- to 34-year-olds say their financial institution is transparent enough about how their personal data is used. At the same time, 30% of this group say they do not know how their data is used. Among Canadians aged 55 and older, that uncertainty rises to 35%.

So yes, customers may be giving permission at the headline level. But underneath that permission is a meaningful layer of ambiguity.

For leaders in data and analytics, marketing, product, and customer experience, that ambiguity creates more than a communications challenge. It can become a performance risk. The more personalization depends on customer data, the more transparency becomes part of the value exchange.

This matters even more as Canadians expect AI to play a larger role in banking. In a recent Leger article on how Canadians want AI to improve the banking experience, our Financial Services team explored how customers want innovation to make banking easier, more relevant, and more useful – not just more advanced.

Customers are not evaluating data use in one uniform way. Age matters, especially when the exchange becomes more explicit.

When asked whether they would trade some privacy for more personalized financial advice:

• 51% of 18- to 34-year-olds say they are likely to make that trade
• 38% of those aged 35 to 54 say they are likely to make that trade
• 25% of those aged 55 and older say they are likely to make that trade

For product teams, this creates a design challenge. For marketing teams, it creates a positioning challenge. For data teams, it creates a governance challenge.

A single personalization model, a single consent narrative, and a single “value of data” message will not work equally well across all customer segments. Some customers are ready for more tailored advice if the benefit is clear. Others need stronger control, simpler explanations, and more visible choice.

The same pattern appears when we compare customers of Big 5 banks with customers of other financial institutions.

Big 5 customers show higher comfort with data-driven tailoring: 78%, compared with 65% among non-Big 5 customers.

But perceived transparency is essentially identical. Among both Big 5 and non-Big 5 customers, 42% say their financial institution is transparent enough about how their personal data is used.

Uncertainty is also similar. Nearly one-third of customers say they do not know how their data is used: 31% among Big 5 customers and 33% among non-Big 5 customers.

This is where leaders need to be careful. Higher comfort can look like a competitive advantage. But if clarity does not rise with comfort, that advantage may be more fragile than it appears.

The question is not only, “Do customers trust us enough to say yes?”

It is also, “Do they understand us well enough to keep saying yes?”

This connects closely to another recent Leger analysis on consumer trust in Canadian financial regulation, which shows how financial trust increasingly depends on protection, clarity, and confidence in the systems surrounding financial services.

For data and analytics teams, the next maturity leap is not only better model performance. It is customer-level explainability.

“I don’t know how you use my data” should be treated as a measurable warning signal, not background noise. A permission dashboard could sit alongside model monitoring, tracking not only consent but comprehension.

For marketing teams, personalization should not be positioned as a vague benefit. It should be framed as a clear exchange: better relevance, better advice, and better experiences in return for specific, understandable uses of customer data.

Younger customers may be more open to that exchange, especially when the value is concrete. Older customers are less likely to trade privacy for personalization, which means reassurance alone is not enough. They need simple choices, clear controls, and visible boundaries.

For product teams, the opportunity is to make transparency part of the experience itself. This could mean clearer explanations at the point of data use, easier preference settings, and product flows that show customers what they get in return for sharing more information. In other words, control should not sit only in the privacy policy. It should show up inside the product.

Financial institutions should not treat customer data permission as only a compliance artifact.

The Office of the Privacy Commissioner of Canada notes that meaningful consent requires clear information about what organizations are doing with personal information. In practice, that means comprehension is central to consent, not a nice-to-have layer around it.

Our research suggests that transparency is becoming a commercial differentiator. When comfort is high but clarity is low, the challenge is not simply to collect consent. It is to design a permission model customers can understand, trust, and sustain.

That model sits across data, marketing, product, and customer experience. It needs the same rigour as the personalization stack itself.

Because if customers cannot explain how their financial institution uses their data in one sentence, has the institution really earned scalable permission?

This is also a brand promise issue. As we explored in our article on promise-resilience risk in Canadian financial institutions, customers test financial institutions not only on what they say, but on whether the experience holds up when pressure rises.

Leger’s Financial Services team can help financial institutions identify where permission is strong, where it is fragile, and which customer segments are most likely to reward deeper personalization versus stronger control.

Data-driven growth will depend on personalization. But lasting growth will depend on whether customers understand the exchange.
