The Canadian Parliament is a bicameral institution and researchers should therefore be prepared to trace all Bills (and most other matters) through both Chambers (the House of Commons and the Senate).
Parliament dissolves itself when a government falls or an election is called. Each election brings forth a new, numbered, "Parliament" which is then broken down into numbered "Sessions." It is important to know the Parliament and the Session before beginning to conduct research as matters, bill numbering for instance, generally start afresh with each new session.
Bills are proposed pieced of legislation, To become law, they must be 'read' (considered) three times by each chamber. They are also considered by a Committee, normally between their second and third reading. This must be done in both chambers and so researching a bill's passage involves looking at four sets of proceedings (House of Commons, Commons Committee, Senate, Senate Committee).
