Canada formalized its minimum protection standards for marine protected areas on Wednesday at a global ocean conservation summit in Vancouver. Oil and gas activity, mining, the dumping of certain waste materials and destructive bottom trawling fishing won’t be allowed in any MPAs established from April 2019 and onward, said federal Fisheries Minister Joyce Murray and Steven Guilbeault, minister of Environment and Climate Change Canada, during a press conference at the IMPAC5 summit.
