Section 57 — Canada Business Corporations Act: Unauthorized signature

An unauthorized signature on a security before or in the course of its issue is ineffective, except that the signature is effective in favour of a purchaser for value and without notice of the lack of authority, if the signing has been done by an authenticating trustee, registrar, transfer agent or other person entrusted by the issuer with the signing of the security, or of similar securities, or their immediate preparation for signing; or an employee of the issuer or of a person referred to in paragraph (a) who in the ordinary course of their duties handles the security.
