I thank hon. members for their interventions on this. The rule is that members have to be in their seats, and by the way, stay in their seats until they vote, when the Speaker starts reading the motion. The important thing is that members hear what they are voting on, the whole thing. Therefore, members have to be in the chamber when the Speaker starts reading the motion.
In the House of Commons on May 11th, 2016. See this statement in context.
