Parking Enforcement Officers employed by the city of Montreal are a sub-division of the Montreal police force, the Montreal SPVM (Service de police de la Ville de Montréal) where they are nicknamed "Green Onions" due to their formerly green uniforms.
Creton, who is of French origin, also had harsh words for the staff responsible for monitoring parking meters - green onions - which, according to him, sometimes appear "arrogant, vulgar and disgraceful. They are aggressive and strike without warning. He then adds that he regularly notices them (green onions), on Peel Street, waiting for the parking meters expire as to immediately impose fines on motorists.
