Which province's child support table applies if parents live in different provinces?

Under the Federal Child Support Guidelines, the provincial table that applies is the table for the province where the payor parent ordinarily resides. The table is linked to the payor's location, not the recipient's or the child's. This means if the payor lives in Alberta and the child lives in Ontario with the other parent, the Alberta table is used to calculate the base monthly amount.

This rule can produce different results because each province's table reflects different local tax rates and cost-of-living factors. A payor in a province with lower taxes may owe a different amount than a payor in Ontario earning the same gross income. The table for each province is published by the federal government and is regularly updated.

If the payor does not reside in any Canadian province — for example, they live outside Canada — the table for the province where the child resides or another applicable table is used. Cross-provincial or international cases also raise questions about enforcement, jurisdiction, and which court has authority. Establishing proper jurisdiction before bringing an application is important in interprovincial cases. A lawyer experienced in interprovincial family law matters can help you navigate which court to use and how to enforce a support order across provincial lines.
