Mr. Speaker, I only want to add that the rules do not state that people be allowed to hear. Rather, Standing Orders 16 and 18 specifically forbid people from interrupting and speaking disrespectfully. Therefore, the onus of our rules is on the individual to not interrupt or speak. That may be for the purpose of allowing other people to hear, but the rules are violated whenever someone is interrupted or treated disrespectfully.
In the House of Commons on December 7th, 2021. See this statement in context.
