I think it's a bit problematic. It technically can allow any minor to apply for citizenship, not just minors who have no parent or legal guardianship, and currently the minister has the ability to waive the age requirement so that minors can apply on their own behalf.
I think it also would be problematic if somebody came in as a permanent resident and the child can get citizenship right away, but their parents did not. It becomes a conundrum in that the child would already be a citizen but the parents would not.
In addition, I think it would not prevent the parents or guardians from being able to coerce the minor into applying for citizenship, which may be potentially against the best interests of the child. I would vote against it.
