It's seven five-minute questioning rounds, so seven times five. There are seven members each speaking and each having five minutes, which would go Conservative, NDP, Conservative, NDP, Conservative, NDP, Conservative. That way every member of the committee gets one round to ask questions before anybody gets a second. Of course if you want to transfer your time, you can do so within your own party, or whatever the case is.
