Section 56 — Canada Business Corporations Act: Staleness as notice of defect

After an event that creates a right to immediate performance of the principal obligation evidenced by a security, or that sets a date on or after which a security is to be presented or surrendered for redemption or exchange, a purchaser is deemed to have notice of any defect in its issue or of any defence of the issuer, if the event requires the payment of money or the delivery of securities, or both, on presentation or surrender of the security, and such money or securities are available on the date set for payment or exchange, and the purchaser takes the security more than one year after that date; or if the purchaser takes the security more than two years after the date set for presentation or surrender or the date on which such performance became due.
