Some private Members’ public bills originate in the Senate and are sent to the House of Commons after passage by the Senate. These bills must be sponsored by a Member of the House of Commons in order for them to be debated and voted upon in the House
When the Speaker calls “First Reading of Senate Public Bills” during Routine Proceedings, the Member sponsoring a Senate bill in the House is permitted to give a brief explanation of its purpose, without engaging in debate. The motion for first reading is then adopted without debate, amendment or question put, and the bill is automatically added to the bottom of the Order of Precedence for Private Members’ Business without having gone through the draw process.
A Member does not lose his or her place on the List for the Consideration of Private Members’ Business if he or she sponsors a Senate public bill but may sponsor only one such bill in the course of a Parliament.
