As a Canadian, I have mixed feeling about this. You can develop and build domestic defence industries, but it only becomes economical if you can develop an export market. Even then, the inputs for parts/resources are still global.
Sweden has one heck of a domestic defence industry, but it's tailor made for its requirements and expensive. The SAAB Gripen is one of the best planes in the world for what it was designed to do: operate dispersed off of regional roads when your main infrastructure is destroyed or unavailable. But its flyway cost is the same as an F-35 because hundreds have been built instead of thousands. And the Gripen's engine is still from General Electric.
The NLAW anti-tank weapon is a good example of export success. It was developed jointly with the British and has had a lot of exports and proven success in Ukraine.
On top of that, Canada's defence civil service is terrible at procurement. Even when we buy foreign, we manage to drive up the costs to the point where its rediculously price just to shove in some domestic "advantage", rather than focusing that money on stuff we are really good at (we tend to kick ass at sonar and anti-sub tech, for example).
The Gripen could have been designed around the EJ200 or Snecma M88 instead.
