In short, no. Limiting or denying the rights of the other parent is frowned upon by the courts, and should not be done without a court order. The law in Ontario holds that support and access/custody are not linked in this way, and does not look kindly on parents who attempt to exercise “revenge”.
However, if your child’s parent has not made their support payments as outlined in your separation agreement, you have the option of filing it with the family court. The family court will then forward your agreement to the Family Responsibility Office, who can use other methods of enforcement.
If you do not have a separation agreement, but have a court order, you have the option of filing a contempt motion in family court. In this way, the court can exercise its discretion to enforce the payment of support by levying a fine against the other parent, or in some extreme cases, imprisoning them.
