CANSEC has been held annually in Ottawa since 1998 by the Canadian Association of Defence and Security Industries (CADSI). CANSEC has always been a great success, and CANSEC 2025 will once again showcase leading-edge technologies, products and services for land-based, naval, aerospace and joint forces military units. CANSEC is also a one-stop shop for first responders, police, border and security entities and special operations units.
