About this event

CANSEC is Canada's leading defence, security and emerging technology trade show, produced every year in Ottawa since 1998 by the Canadian Association of Defence and Security Industries (CADSI). Over two days it puts prime contractors, supply-chain firms and technology companies in front of senior military leaders, federal officials and foreign delegations, which makes it the main place where Canadian defence procurement conversations happen in person.

Who attends

The show draws a concentrated audience of senior military and government representatives, elected and appointed officials, international delegations and defence industry executives, from large primes down to small suppliers and firms entering the defence market for the first time.
