The Conflict of Interest Code for Members of the House of Commons prohibits Members from participating in debates on and from voting on questions in which they have a private interest.
A Member who has a private interest that might be affected by a matter that is before the House of Commons or a committee of which they are a member must, if present during consideration of the matter, disclose orally or in writing the general nature of the private interest at the first opportunity. The general nature of the private interest will be disclosed immediately to the Clerk of the House. If the Member becomes aware at a later date of a private interest that should have been disclosed, they must do so right away.
The Clerk of the House will have the disclosure recorded in the Journals and send it to the Conflict of Interest and Ethics Commissioner, who will file it in the public registry.
In any other circumstances involving a Member’s parliamentary duties and functions, a Member who has a private interest that might be affected shall disclose, orally or in writing, its general nature at the first opportunity to the party concerned. The Member must also file a written notice concerning the private interest to the Commissioner, who will post it in the public registry.
