(Nick Murray/CBC News) Nunavut's Qikiqtaaluk communities are still concerned about the impact on marine wildlife if production ramps up at the Mary River Mine. The issue was brought up Monday in Iqaluit during the first day of the final public hearings into Baffinland's Phase 2 expansion proposal. Baffinland is requesting to double its shipping of iron ore from its Milne Inlet port to 12 million tonnes a year, which would see around 168 ships sail through waters near Pond Inlet, Nunavut, a summer home to one of the world's largest narwhal populations.
