I think it would depend on the deliberations of this committee.
If at the end of your deliberations you reach a consensus—let's say that everyone agrees to a particular proposal and everyone has signed on, and you have in fact reached as many witnesses and as many Canadians as possible—that might, as you say, be enough.
If, however, you don't reach a consensus on the committee, then it might make sense—this is just throwing out an idea—to say that there are, for example, two options that need to be further looked into and that you recommend that we narrow it down to these two and then set up some sort of commission that will look more deeply into the two options and then make a recommendation. Then you would extend the process slightly, if there isn't consensus.
If it's the case that you have most of the political parties on the special committee in agreement, I think it would be a good sign. If you have in the legislative arena the majority of the popular vote onside, again I think that would be enough.
There's not, then, one answer. It really depends upon what this committee comes to decide in the next few months and the number of parties that are in agreement.
