Employees and contractors at Canada Life will be asked to voluntarily attest to their vaccination status by that date, with rapid testing to be implemented for those who are unable to be vaccinated or haven't shared their vaccination status, according to the email, which was shared with Reuters.

Last week, Canada's biggest banks said they would all require employees working on their premises to be vaccinated from this fall.

Sun Life Financial, another Canadian life insurer, recently updated its guidance to require employees that are part of its return-to-office pilot to be fully vaccinated.
