Child support in Canada is calculated using the Federal Child Support Guidelines based on income and number of children.

The Federal Child Support Guidelines provide standardized calculations for child support payments across Canada. The basic amount is determined by combining three key factors:

• The paying parent’s gross annual income
• The number of children requiring support
• The province or territory where the paying parent lives

Additional special expenses may be added to the basic amount, including:

• Childcare costs
• Medical and dental expenses not covered by insurance
• Post-secondary education expenses
• Extracurricular activities costs

Parents can use the Child Support Look-up Tables available through the Department of Justice Canada to determine the basic monthly payment amount. These tables are updated periodically to reflect economic changes.
