Aligning Ontario’s industrial capacity with defence priorities

ODA supports this direction by organizing industry input, building supplier readiness, mapping capability, convening partners, and helping Ontario firms understand where they fit in the defence and dual-use economy.
“Ontario is the trusted industrial and innovation backbone for Canada and its allied partners, where defence and dual-use capabilities are invented, built, scaled and exported.”
