I would say, yes, Canada does need more sovereign ISR satellites. At the same time, Canada benefits from being part of CSpO, the combined space operations initiative, which started as a Five Eyes alliance but now includes Germany, France, Italy and Japan. That is about sharing space-based intelligence.
Canada is a middle-sized economy. It's a middle power. It can't do everything. No country can do everything on its own in space these days.
I also think that space technology collaboration can be used as a policy lever for other interests. However, when it comes to ISR needs in particular, yes, Canada needs more dedicated sovereign capability, but it can also continue to benefit from that international partnership.
