Section 66.1 — Canada Pension Plan: Request to cancel benefit

A beneficiary may, in prescribed manner and within the prescribed time interval after payment of a benefit has commenced, request cancellation of that benefit. Subsection (1) does not apply to the cancellation of a retirement pension in favour of a disability benefit where an applicant for a disability benefit under this Act or under a provincial pension plan is in receipt of a retirement pension and the applicant is deemed to have become disabled for the purposes of entitlement to the disability benefit in or after the month for which the retirement pension first became payable. Where a request made under subsection (1) or under a substantially similar provision of a provincial pension plan is granted and the amount of the benefits paid is repaid within the prescribed time or, in the case of a provincial pension plan, the time provided thereunder, that benefit shall be deemed for all purposes of this Act not to have been payable during the period in question.
