Just before we move on, on the issue of ministers, on page 848 of Marleau and Montpetit, in chapter 20, there's a whole paragraph on time for opening remarks and questioning of witnesses. Near the end of the paragraph, it says:
Each committee seeks to balance, as best it can, the desire to ensure that representatives of all parties have the opportunity to put questions. As well, some committees adopt special rules for the questioning of Ministers.
So if we wish to, we can adopt a special rule, and we can put a time limit on the minister himself.
