You can never deny or limit the rights of an access parent without an order of the court. In Ontario the law says that support and custody/access issues are not directly related and one parent cannot obtain “revenge” in this way.
If your spouse has not made their support payment and you have a separation agreement you can file it with the court and who will then forward it to the Family Responsibility Office.
If your spouse has not made their support payment and you have a court order then you can make a contempt motion in court requesting that the court levy a fine or imprison your spouse for failure to pay support.
