Absolutely. If you listen to the Ukrainian fighters and to what the Ukrainian army is saying on the ground when they're asked what concerns them most, the answer is almost always air power. Looking forward at a great-power conflict, air power is crucial. Canada absolutely needs to speed along its acquisition of the F-35s.
From a maritime perspective, submarines are a strategic asset. They are extraordinarily important. They can greatly expand Canada's surveillance of a maritime area and also its ability to exclude hostile powers from that area. The next major capital acquisition that Canada will need to decide upon—and very quickly, might I add—is the purchase of a new conventional submarine fleet.
