(DEFSEC Atlantic)

DEFSEC Atlantic, presented by the Atlantic Canada Aerospace & Defence Association, is a major networking opportunity for the Aerospace, Defence and Security industries - the second largest of its kind in Canada. Focused on showcasing Atlantic Canadian opportunities, the show's worldwide reach creates partnership potential for all attendees. Incorporating elements of both a trade show and a defence procurement conference, it provides access to "the right people" in an engaging and professional setting. All attendees have opportunities, through our B2B/B2G program, social events & communications tools, to interact with all levels of defence, industry and government participants.
