I'm asking about Canada because I'm Canadian, but feel free to discuss other British colonial possessions like India or South Africa, because the concept is the same.

I'm wondering if Canada was able to set their own policies with regard to conscription, arms manufacturing, etc, if Britain controlled the whole process, or some combination thereof.

Also, did Canadian officers have any control over the battles they participate in? I'm thinking specifically of Dieppe where Canadians were slaughtered in a half-hearted D-Day attempt. It seems like the British just sent their "expenadable" colonial soliders to die probing defences. Was this the case at all, or did Canada have a bigger role in choosing where to commit soldiers?

I've touched on a few subjects, any elaboration about anything would be greatly appreciated! Thanks for reading.
