Federal delays are allowing billions of litres of wastewater to be dumped in Canadian waters including marine protected areas, an environmental group says. In a report released this week, the World Wildlife Fund said the federal government has yet to follow through on a three-year-old commitment to bring in new regulations on what waste ships can release into the oceans. It says that lack of progress is allowing ships to keep releasing bilgewater, sewage, grey water and other wastewater.
