City has four Covid hot zones

Montreal has four Covid hot zones: St-Léonard-St-Michel, Ahuntsic-Montreal-North, Nord de l’Île-St-Laurent and RDP/Anjou/Montreal East. I am not clear on the definition of “Nord de l’Île” which I haven’t seen before as a descriptor. This piece says François Legault is going to “sortira bientôt l’artillerie lourde” in these areas.
