An engineer may carry on his or her professional activities within a joint-stock company constituted for that purpose before 21 June 2001 until the coming into force of the first regulation made by the Order under paragraph p of section 94 of the Professional Code (chapter C-26). From the coming into force of the regulation, an engineer may carry on his or her professional activities within such a company insofar as the engineer complies with the provisions of the regulation. The regulation may nevertheless provide that an obligation, term, condition or restriction in respect of the carrying on of professional activities within a joint-stock company shall not apply to the engineer until the expiry of a certain period of time, which may not exceed one year from the coming into force of the regulation.
