21.11.11. A short-term preferred share of a corporation at any particular time is a share, other than a grandfathered share, of the capital stock of the corporation issued after 15 December 1987 that, at that particular time, is(a) a share where, under the terms and conditions of the share, any agreement relating to the share or any modification of such terms, conditions or agreement, the corporation or a specified person in relation to it is or may, at any time within five years from the date of its issued, be required to acquire, cancel or redeem, in whole or in part, the share or to reduce the paid-up capital of the share, unless the requirement to acquire, cancel or redeem the share arises only in the event of the death of the shareholder or by reason only of a right to convert or exchange the share, or
(b) a share that is convertible or exchangeable at any time within five years from the date of its issue, unlessi. it is convertible into or exchangeable for(1) another share of the corporation or a corporation related to the corporation that, if issued, would not be a short-term preferred share;
(2) a right or warrant that, if exercised, would allow the person exercising it to acquire only a share of the corporation or a corporation related to the corporation that, if issued, would not be a short-term preferred share, or
(3) both a share described in subparagraph 1 and a right or warrant described in subparagraph 2, and
ii. all the consideration receivable for the share on the conversion or exchange is the share described in subparagraph 1 of subparagraph i or the right or warrant described in subparagraph 2 of the said subparagraph i or both such share and such right or warrant, and, for the purposes of this subparagraph, where a taxpayer may become entitled upon the conversion or exchange of a share to receive any particular consideration, other than consideration described in any of subparagraphs 1 to 3 of subparagraph i, in lieu of a fraction of a share, the particular consideration is deemed not to be consideration unless it may reasonably be considered that the particular consideration was receivable as part of a series of transactions or events one of the main purposes of which was to avoid or limit the application of Part IV.1 or VI.1 of the Income Tax Act (Revised Statutes of Canada, 1985, chapter 1, 5th Supplement).
