That's great. An extra meeting wouldn't be a problem at all, but you'd need at least three. You'd obviously want one to report back to the finance committee on what you're doing. You have to draft a letter and say yes or no, and there may be the odd amendment that we would propose, and we need to discuss those as well.
I would say two meetings for witnesses and a wrap-up meeting to send it back. Normally the process would be that the government introduces legislation, such as Bill C-58, and then it goes to second reading, has a vote, and comes to a committee, and we discuss it then. It normally doesn't go as separate legislation and then is thrown into a budget implementation bill like that. But that's okay. We've talked about that now, so this would be good: two meetings for witnesses and one to wrap up and send it back.
