Half the population of St-Jean-sur-Richelieu, 30 kilometres southeast of Montreal, have been without drinking water since a major water main break at the beginning of the week. The city declared a local state of emergency on Wednesday. The water cutoff affected more than 26,000 residential, commercial and industrial addresses in the St-Luc and L’Acadie sectors as of Wednesday afternoon, as well as part of the St-Jean sector, all on the western side of the Richelieu River.
