I totally understand where you're coming from in the desire to have that kind of analysis. Right now we can ask the Library of Parliament to do a broad overview. That's a great resource. I've never heard a complaint from them.
I will say, though, that I am worried by making it a parliamentary legal requirement where, by law, the parliamentary budget officer has to acquiesce to a request. To me, the word “shall” is very strong language, and the problem is you have limited resources and infinite desires. I'm afraid there could be vexatious demands on the office. Again, we would all hope that people would use their reasonableness when carrying out their parliamentary duties.
To me, a better amendment would be perhaps if a group of members of Parliament—maybe that could be quorum, 12 in the House of Commons—agreed that they'd like something done. It would be like a committee. That would be a reasonable request. Then you would at least have a group of MPs and a public interest.
In this particular format, I just cannot support it on the principle of trying to keep those scarce resources focused on it.
I also have to be a better MP if I'm going to make a case to the parliamentary budget officer to investigate something. The onus is on me to actually argue there is a wider public interest than just my curiosity.
