what is the maximum one can claim?
Maybe clarify your situation
were you a pr/citizen during this time you speak of?
This “old” benefits you are speaking of, were you already living in Canada with your under 18 year old child?
what do you mean by you did not receive it?
from your posts, it does not seem like you have been filing taxes. No expert here but yoy need to file taxes to be eligible for benefits is what i know.
