Halifax Convention Centre named new venue
for DEFSEC Atlantic 2021!

The Canadian Defence Security and Aerospace Exhibition Atlantic, the region's largest annual aerospace and defence tradeshow will be held at the Halifax Convention Centre for the first time on October 5-7, 2021. Our team is pleased to confirm planning is underway for our event being held in downtown Halifax, Nova Scotia, Canada.

We are working to maximize safe, in-person participation permitted under the provincial recommendations and within established safety guidelines. Virtual and hybrid participation options will also be available for national and international participants who cannot travel to engage with our regional industry representatives. Hopeful that our pandemic recovery continues to loosen the restrictions, we are planning for Canadian Forces in-person participation and are anticipating over 600 attendees from within a re-established "Atlantic Bubble".

A COVID-19 event plan is being submitted to the province for approval and continual refinement to ensure that all public health guidelines are followed in the production of this October 2021 event! The Halifax Convention Centre has already been an engaged partner in the planning of the event to ensure that all those attending are able to so in a safe manner. The organizers will continue to work with the venue and the province to ensure all the latest protocols and guidelines will be in place for the event.

It is important to note that any changes in Nova Scotia COVID-19 regulations may lead to changes in virtually any aspect of the event. The web site will be the primary means of updating attendees of the evolution of the event, along with our eNewsletter and social media.

Those companies and organizations interested in becoming an exhibitor should look at our standard and hybrid booth options, review the floorplan and contact Show Management.
