Change in process: Implementation of Certified Mail for the Disability Insurance (DI) Plan


To: Heads of Human Resources, Compensation Managers and Participating Separate Employers


The purpose of this Notice is to provide information regarding a change in the way electronic mail is sent from Sun Life, as the insurer of the Disability Insurance (DI) Plan, to compensation managers and employers.


The Treasury Board of Canada Secretariat Pensions and Benefits Sector in collaboration with Sun Life have been exploring options to securely transfer member information.

Sun Life's "secure messaging" Website using "Certified Mail" was approved as the solution and Sun Life has begun using the Secure Messaging Website when sending email to compensation advisors.

What is Certified Mail?

Certified Mail is a tool that allows Sun Life to exchange emails with external contacts without information being disseminated over the internet. To access a Certified Mail email message, the recipient will require a password which will allow them to view the message from a secure location within the Sun Life firewall.

Why use Certified Mail?

Sun Life as the insurer of the Disability Insurance Plan must exercise due diligence in the protection and security of personal and business information.

Certified Mail provides an extra layer of security to emails that are exchanged as private or confidential, such as information related to an employee's health or employment status.

Certified Mail uses a secure connection. Compensation advisors must use a password to access messages from a secure location within the Sun Life firewall.
