Confirm your permanent residency by telephone? Scam or not?

In the past few months IRCC has been sending emails inviting selected Permanent Resident applicants who are in Canada, to be part of a new initiative that allows them to confirm their permanent residency by telephone. This new method allows them to obtain permanent resident status without the need to physically go to a local IRCC office for an appointment.  These invitations  are part  of an effort to provide better client service as can be read on the IRCC website and are absolutely no scam.
