"Legislation, also known as the acts, are forms of law that can provide the authority to make regulations. Generally, legislation begins as a bill (draft form), and can originate either in the House of Commons or in the Senate. For a bill to become law, it must be approved by both the House of Commons and the Senate, and by the Governor General of Canada (the Crown). Bills are discussed by members of both Houses during what is formally known as First Reading, Second Reading and Third Reading, and are also submitted to a Parliamentary Committee for review. The Committee usually seeks out the views of interested parties, including the public. The final stage of the enactment of a bill is when it receives Royal Assent. The timing of Royal Assent is determined by the Leader of the Government in the House of Commons in consultation with the Leader of the Government in the Senate. An Act has the force of law upon Royal Assent, unless it is provided in the Act that it will come into force on a day to be fixed by order of the Governor in Council (Cabinet)."
