85. A corporation’s acquisition of a share or a fractional share of its share capital entails the cancellation of the share or fractional share, unless it was acquired under section 47 of the Act respecting the transfer of securities and the establishment of security entitlements (chapter T-11.002). However, if the articles limit the number of authorized shares, the cancelled share or fractional share becomes an unissued share or fractional share, unless otherwise provided in the articles.
