As a passport is now required, if you're over $5000 in arrears, a passport is canceled.Actually you don't need a passport to enter Canada only to get back into the U.S. But I don't know if a child support conviction is grounds for inadmissability. Seeing that child support is not a criminal offence in Canada

Yes, not only arrested but a person can be jailed for failure to pay child support. HOWEVER, if you go voluntarily to the Child Support office or call, they will try to work out payments. Follow your court order and there won't be problems. Children deserve to be supported by both parents.
