A mussel never reported in Canada was identified in the port of Montreal, a soft shell clam never seen in the Arctic was discovered in the Hudson Bay in Churchill, Manitoba, and a barnacle that was not thought to occur north of San Francisco was detected in Nanaimo, British Columbia. These are invasive species and researchers from McGill University detected 24 of these non-indigenous species across 16 major ports in Canada, including 11 that were identified in previously unreported locations. Their findings were published Biodiversity Research.
