Here is a .pdf of the Report on the Operations of the Parliamentary Budget Officer within the Library of Parliament, by the Standing Joint Committee on the Library of Parliament.
The key recommendations are below. I have bolded particularly interesting words.
Recommendation 1
That the Speakers of the Senate and the House of Commons direct the Parliamentary Budget Officer to respect the provisions of the Act establishing his position within the Library of Parliament. The Parliamentary Budget Officer reports to the Parliamentary Librarian and, as a senior official of the Library, it is his responsibility to participate fully in management activities and to work closely with the Library’s other service areas.
Recommendation 6
That the Speakers of the Senate and the House of Commons instruct the Parliamentary Budget Officer that a response to a request made by a parliamentarian or a parliamentary committee in accordance with the legislated mandate shall remain confidential, until the confidentiality is lifted by the parliamentarian or the parliamentary committee making the request.
Recommendation 8
That, on the understanding that any increase of the budget of the Parliamentary Budget Officer is conditional on compliance with all other recommendations in this report, after due process and validation, the Speakers of the Senate and the House of Commons, in collaboration with the Parliamentary Librarian, submit to the Treasury Board a proposal to increase the budget of the Parliamentary Budget Officer for 2009–2010 to $2.8 million, without reducing the current financial resources of the rest of the Library of Parliament.
