The statements you wrote above about not being a citizen also call your mental stability into question, and Tayken has previously posted court decisions where the judge has done exactly this. You are damaging your credibility and greatly reducing your chances of custody.
Actually, the Family Court does not have jurisdiction over tax law. They won't as I stated previously order you to file your taxes, although I have found jurisprudence in the past that they have.
The typical pattern is that they order the past 3 years, give you time to produce them, when you don't then the other party files a contempt of court motion.
The judge will then give you more time to provide a remedy. If you again fail, they will order substantial costs against you. From there the other party's lawyer will start to seek striking of your materials possibly or preventing you from continuing in the case.
Or they will seek a fine. You fail to pay the fine then you will get to meet the law enforcement agent who will seek payment of the fine. Failure to pay will land you back in court.
Or they will reduce access to the child and even make it supervised. An argument can be made that you are a flight risk as you claim to not be "Canadian" and non-resident. Just the utterance of this could find a very strict supervised access at an access centre.
I truly think you are on a good path. I try not to judge you based on your OACP litigation beliefs. But, you draw this into family court and your credibility will be shot before the court.
I implore you to not take this position and re-read Mess' post a few times. I do know you are frustrated and you want to find some "loop hole" in the system of family law. It just isn't there and your argument won't help you.
Your child loves you, needs both parents equally involved in their lives, and children are about sacrifice. This might having to sacrifice your personal beliefs in the OACP litigation world - for the best interests of your child and so you can be a father to this child.
Good Luck!
