The reasons you stated are not grounds fo asylum: "bad circumstances of living or poor health care that’s may put the kids who born in Canada in serious danger." I agree that you should be seeking the advice of a lawyer. I don't think there are exceptions. Canada has offered you protection, healthcare, welfare, education, etc. In exchange the only thing that is required is that you not return to your home country until you are a citizen and that you don't renew your passport. You will have to weigh the risks after speaking with a lawyer.
