About Defence Technology in Canada
Defence technology covers uncrewed air, ground and underwater systems, sensors and surveillance, secure communications, electronic warfare, simulation and training, and the software that ties them together.
Much of the work is dual-use — the same autonomy stack or sensor sells into resource industries and into a military programme — so companies here often appear under a second sector as well. Procurement is slow and contract-driven, and the highlights on each record link to the announcements themselves.
How this list is built
Every Defence record here is hand-checked, and the 153 claims across them each link to a page you can open. Where a figure is not published, the field is left blank rather than estimated.
