The orca — also known as the killer whale — is one of the most iconic and well-studied species on Canada’s West Coast.
Canada is home to five distinct populations of orcas, each with unique genetics, diets, behaviours, and cultural traditions, such as hunting techniques and vocalizations. These populations include:
Northern Residents, West Coast Transients, Offshore populations, Northwestern Atlantic and Eastern Arctic population and the Southern Residents — a critically endangered group, with only 73 individuals remaining.
Each population plays a vital role in our marine ecosystems, and protecting them means understanding their unique challenges and needs.
