Canada is a typical maritime country,fisheries economic prosperity and marine sustainable development have been the main management and research work. From two perspectives of research literatures and latest strategic plans,this paper studied the ocean research priorities and hot trends of Canada. The study found that the marine science and technology in Canada focuses on marine populations and ecosystems,protection of the marine environment and species,marine monitoring and data information,marine technology and management tools,Climate change and arctic research,deep-sea material energy and driving mechanisms. In the future,Canada will continue further study on arctic research,global warming,ecosystem monitoring,deep-sea exploration,marine new energy and new technologies. In summary,Canada's research situations and development trends may provide a useful reference to China's development of the marine industry.
