The federal government has made new anti-pollution measures mandatory for cruise ships, but environmental groups say they don’t stop contamination of some of Canada’s most sensitive coastlines. Transport Minister Omar Alghabra announced recently that voluntary guidelines established in April are now mandatory. Those rules cover the discharge and treatment for so-called black water, or stuff from toilets, and grey water, kitchen water, water from laundry machines, and water containing cleaning products, food waste, cooking oils/grease and other pollutants.
