PIPEDA Case Summary #2017-006: Using SIN for identity verification cannot be a condition of service
The Office of the Privacy Commissioner of Canada (OPC) investigated a complaint that a financial institution required customers to provide their Social Insurance Number (SIN) for identity verification purposes as a condition of opening a savings account. The OPC found that while the institution collected SINs for legally required income reporting, it could not mandate its use for identity verification. The institution agreed to make the use of SIN for identity verification optional rather than a condition of service.
