(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, presentations & expert panel discussions and communications tools, to interact with all levels of defence, industry and government participants.

DEFSEC Atlantic Policy Change for COVID-19 Protocols

Masks are now not mandatory at DEFSEC Atlantic 2022

We continue to take the health of our attendees and volunteer staff very seriously.  The evolution of the pandemic and our collective reactions and methods of addressing it cover a wide spectrum.  It is in keeping with societal norms and the recent government of Canada policy change on entry into Canada that we are adjusting our policy.  We continue to have and will enforce a COVID-19 declaration as a requirement of registration and attendance.

The wearing of masks, social distancing and good hygiene practices are encouraged, but no longer required.  This will be supported by our important sponsorship of personal protective equipment by Chantier Davie Canada.

Masks and hand sanitizing stations will be available at all entry points and in strategic locations throughout the DEFSEC Atlantic event venue.

We look forward to welcoming you to Halifax and wish you a healthy and successful experience!

DEFSEC Atlantic unaffected by Hurricane Fiona

We would just like to share that while the impacts of Hurricane Fiona have been felt across Atlantic Canada, DEFSEC Atlantic on October 4-6 at the Halifax Convention Centre has thankfully not been impacted.

The Halifax Convention Centre is back up and running as of Monday morning (Sep 26) here in Halifax and our preparations continue. We remind everyone, particularly exhibitors, but all attendees, please complete your online registration for DEFSEC Atlantic prior to arriving at the venue. This will result in shorter wait times and a more efficient process of getting you checked in at our CAE Registration Desk.
