Ontario’s defence sector is growing rapidly, driven by cutting-edge technological innovation, skilled talent development, and world-class manufacturing expertise. We are home to a diverse industry, supported by private-sector companies, researchers, and innovators, with capabilities across several subsectors including aerospace/space, munitions/weapons, naval, combat vehicles, soldier systems, and C4ISR.

From September 9–12, 2025, Ontario’s Ministry of Economic Development, Job Creation and Trade will lead an Ontario Defence and Security Export Business Mission to DSEI 2025, the U.K.’s premier global defence trade show at ExCeL London (sourcefromontario.com/DSEI). The ministry will showcase Ontario’s world-class innovation across land, air, sea, cyber, and space, representing a network of over 300 companies excelling in defence and security, aerospace, AI, cybersecurity, avionics, and space systems.

Located at booth S5-358, the Ontario delegation will leverage the DSEI international platform to connect companies with global procurement officials, industry leaders, and potential partners. The mission will feature B2B matchmaking, networking events, and opportunities to position Ontario firms in European and other key defence markets.
For Canadian defence exporters, Ontario’s presence underscores the province’s ambition to be a global hub for defence innovation and exports, offering new and experienced exporters alike an opportunity to engage with thousands of decision-makers in a single, high-impact week.
