New Democratic Party House Leader Nathan Cullen says Speaker Andrew Scheer needs greater clout to keep politicians in line.
Cullen wants the Speaker to be able to bar MPs from asking questions in the Commons if they don't heed warnings to be civil.
It's not the first time the New Democrats have called for greater powers of punishment for the Speaker.
Cullen's predecessor, Joe Comartin, asked for the same thing last fall.
But Cullen says behaviour in Parliament is getting worse and MPs need to be reined in.
