Thank you, Mrs. Thomas, for the question.
The Governor in Council is the typical process used for regulation-making in many instances when it's not the regulatory body making those regulations but rather the government. The way that is typically done is that a government department would pre-publish proposed regulations in part I of the Canada Gazette for consultation, and stakeholders would have an opportunity to consult on those proposed regulations.
The sponsoring government department would then seek to finalize those regulations, and the responsible minister would bring a regulatory package forward to the Treasury Board. It is the cabinet committee that is responsible, generally, for making Governor in Council regulations, and that regulatory package would be reviewed and approved by the Treasury Board.
The final regulations are published in Canada Gazette part II.
