Section 21.1 — Canada Pension Plan: Liability

If an employer who fails to deduct or remit an amount as and when required under subsection 21(1) is a corporation, the persons who were the directors of the corporation at the time when the failure occurred are jointly and severally or solidarily liable, together with the corporation, to pay to Her Majesty that amount and any interest or penalties relating to it. Subsections 227.1(2) to (7) of the Income Tax Act apply, with such modifications as the circumstances require, in respect of a director of a corporation referred to in subsection (1). The provisions of this Act respecting the assessment of an employer for an amount payable by the employer under this Act and respecting the rights and obligations of an employer so assessed apply in respect of a director of a corporation in respect of an amount payable by the director under subsection (1) in the same manner and to the same extent as if the director were the employer referred to in those provisions.
