Again, that seems to be an entirely symbolic gesture. In fact, if you go to the website of the Canadian Armed Forces, the number one requirement for joining the Canadian Armed Forces is that you must be a Canadian citizen.
If you ask where it makes more sense to deploy resources, it seems to make more sense to deploy them in the processing of citizenship applications. What I have heard is happening now is that resources are being deployed to deal with the very lengthy residence questionnaires that are now being administered and no additional resources are being put into actually processing more quickly.
Now I understand that will change if the government increases the cost of citizenship applications to make applicants pay for the extended process, but I don't know much about that.
