The Maritime & Arctic Security & Safety Conference (MASS) is Canada’s signature event for exploring challenges and opportunities in northern and maritime environments, now in its 13th year. Hosted by the Atlantic Canada Aerospace & Defence Association (ACADA), this three-day international conference brings together military professionals, government officials, industry leaders, and academia to address emerging threats and showcase Canadian innovation. The conference focuses on how Canadian companies provide safe, secure solutions for North America and the world through products, services, and research in Arctic security, maritime domain awareness, surveillance technology, climate change impacts, telecommunications infrastructure, and Indigenous partnerships. MASS features keynote presentations from senior military commanders including NATO officials, panel discussions on critical topics such as Arctic sovereignty, underwater surveillance, and marine climate monitoring, facilitated B2B/B2G meetings, and 15+ exhibitors showcasing cutting-edge maritime and Arctic technologies. Held at the renovated St. John’s Convention Centre overlooking the historic harbour, MASS attracts 200+ attendees from across Canada, the United States, Europe, and the Arctic region. The event offers unique networking opportunities and Warriors Corner-style presentations addressing operational challenges, R&D breakthroughs, and policy developments.
