The parent with day-to-day care of the child is paid child support from the other parent. If the parents have more than one child, then child support is paid for each child. The amount paid is decided by the total income of the payor parent using the Federal Child Support Guidelines or the Alberta Child Support Guidelines.
Both parents pay child support when the parent with less time has the child for at least 40% of the month. Each parent pays child support based on their total income and the Guidelines. The parent with the higher child support obligation pays child support less the amount that would have been paid by the other parent.
Child support can also include a top-up amount to help cover any extra expenses like childcare, sports, dental or medical costs.
