Claims added to proceedings
21 Despite the expiry of the relevant limitation period established by this Act, a claim may be added, through a new or an amended pleading, to a proceeding previously commenced if the added claim is related to the conduct, transaction or events described in the original pleadings and the conditions set out in one of the following paragraphs are satisfied:
(a)
the added claim is made by a party to the proceeding against another party to the proceeding and does not change the capacity in which either party sues or is sued;
(b)
the added claim adds or substitutes a defendant or changes the capacity in which a defendant is sued, but the defendant has received, before or within 6 months after the expiry of the limitation period, sufficient knowledge of the added claim that the defendant will not be prejudiced in defending against the added claim on the merits;
(c)
the added claim adds or substitutes a claimant or changes the capacity in which a claimant sues, but the defendant has received, before or within 6 months after the expiry of the limitation period, sufficient knowledge of the added claim that the defendant will not be prejudiced in defending against the added claim on the merits, and the addition of the claim is necessary or desirable to ensure the effective determination or enforcement of the claims asserted or intended to be asserted in the original pleadings.
