Don’t know about Canada, but there is a rule in the US that Sergeant at Arms has the authority to use the mace as a weapon against an unruly member. To my knowledge, that has never happened as most members had respect for tradition and complied once the Sergeant at Arms ceremoniously raised the mace
During the January 6 riot/insurrection, no members were in the chamber so the Sergeant at Arms didn’t have the opportunity to use the mace as a weapon. I don’t think that I would have wanted to face a PO’d mob with only a stick
