The Canadian lender says in a statement the problem related to an electronic form on its website and did not expose clients’ banking information, social insurance numbers or addresses.
The bank says a customer filling out an online form to make a branch appointment may have been able to see the data entered by a previous user.
National Bank says it was notified earlier this week about the problem, which lasted a few days.
The lender adds the incident was the result of human error while setting up the online form, and was resolved immediately.
The bank is contacting the nearly 400 potentially-affected customers to offer free credit monitoring.

We both have life insurance policies with our employers—mine is about equal to what this policy would pay and my husband’s is less, although he plans to either fully retire or semi-retire in 2018. Our home and cottage are both paid off and we have no debt. Our three children are in their 20s, out of the house and mostly self-sufficient, and we have saved about $450,000 for retirement so far. I have a DB pension plan and he has a DC plan…
