17. No document is binding on the corporation unless it is signed by the president or, in the cases determined by by-law of the corporation, an employee of the corporation.
The corporation, by by-law, may, on the conditions it determines, allow a required signature to be affixed by means of an automatic device to the documents it determines, or a facsimile of a signature to be engraved, lithographed or printed on them. However, the facsimile does not have the same force as the signature itself unless the document is countersigned by a person authorized by the president.
