Yes. It has to be manageable to be fair. It would be an administrative burden on the commissioner, but the blanket five-year cooling-off period was extended to all MPs and their staff because of the scandal involving a former MP back in 2010. It shouldn't have been extended to everybody as the same five-year blanket rule. It doesn't make sense. It's unfair.
A sliding scale would be fair. It would take a lot of work, but it would be fair. People should have the right to go out and be a lobbyist if they haven't really done much...if they were a backbench MP and on no committees, or a low-level staff person there temporarily, not known to be anybody in the government.
