Child Support in Canada: What Parents Need to Know

Separation and divorce are never easy, especially when children are involved. One of the most important—and often most misunderstood—aspects of the process is child support. In Canada, child support is not a negotiation tool or a privilege; it is a fundamental legal right of the child.

As Canadian family lawyers, we believe that understanding the system is the first step toward achieving a stable future for your family. This guide breaks down what child support is, how it’s calculated using the Federal Child Support Guidelines, and what happens when payments fall into arrears.

1.What is Child Support in Canada?

Child support is the financial contribution paid by one parent (the payor) to the other parent (the recipient) to help cover the costs of raising the children.

The Legal Foundation

In Canada, child support obligations are governed by two main bodies of law, which largely operate in harmony:

• The Federal Divorce Act: Applies to parents who are legally married and are seeking a divorce.
• Provincial or Territorial Family Law Legislation (e.g., the Family Law Act in Ontario, the Family Law Act in British Columbia): Applies to married parents not seeking divorce, common-law partners, and other relationship arrangements.

Both sets of legislation rely heavily on the Federal Child Support Guidelines to ensure consistency and fairness across the country.

2. How is Child Support Calculated?

The Canadian system is designed to be highly standardized, taking much of the guesswork—and potential conflict—out of the basic calculation.

The Table Amount

The core monthly amount of child support is called the “Table Amount“ and is determined using a mathematical formula outlined in the Federal Child Support Guidelines. The calculation depends primarily on three factors:

1. The Payor’s Gross Annual Income: This is generally the income reported on Line 15000 of the payor parent’s T1 Income Tax Return.
2. The Number of Children eligible for support.
3. The Province or Territory where the payor parent resides.

The Table Amount is a set figure that is presumed to cover the basic needs of the child, such as food, shelter, and clothing.

Adjustments for Parenting Arrangements

The calculation can be adjusted based on how parenting time is divided:

1. Sole Parenting Time: If one parent has the children the majority of the time (more than 60%), the other parent is typically the sole payor of the Table Amount.
2. Shared Parenting Time (Section 9): If each parent has the children between 40% and 60% of the time, the Guidelines require a special calculation. This typically involves setting off the Table Amounts that each parent would owe the other and may include a further adjustment based on the increased costs associated with shared care.

3. Understanding Special or Extraordinary Expenses (Section 7)

In addition to the basic Table Amount, parents are usually required to share specific costs for the children that are considered “special or extraordinary.” These are universally referred to as Section 7 Expenses under the Guidelines.

Eligible expenses are those that are necessary (in the child’s best interest) and reasonable (in relation to the parents’ and child’s means and the family’s spending pattern before separation).

Common examples of Section 7 Expenses include:

• Child care expenses (incurred due to work, education, or illness).
• The portion of health and dental insurance premiums attributable to the child.
• Uninsured health-related expenses (e.g., orthodontics, counselling, physiotherapy).
• Extraordinary expenses for extracurricular activities (e.g., competitive sports, specialized arts programs).
• Post-secondary education costs.

The guiding principle for Section 7 Expenses is that they are shared between the parents in proportion to their respective incomes. For example, if Parent A earns 65% of the combined parental income, they contribute 65% of the net cost of the Section 7 expense.

4. Enforcement: What Happens If Payments Aren’t Made?

A failure to pay child support is a serious breach of a legal order. The government does not leave it up to the recipient parent to chase down payments; every province and territory has a specialized agency to enforce court-ordered support.

If a support order is registered with the provincial enforcement body and the payor defaults, the agency can take swift and severe action.

Key Provincial Enforcement Agencies:

• Ontario: The Family Responsibility Office (FRO)
• Alberta: The Maintenance Enforcement Program (MEP)

Common Enforcement Tools:

These agencies have wide-ranging powers to collect arrears, including:

• Garnishment of Income: Direct deduction from wages or bank accounts.
• Garnishment of Federal Payments: Intercepting federal funds, such as income tax refunds, Employment Insurance (EI), or the Canada Pension Plan (CPP).
• Suspension of Licences: Suspending a payor’s driver’s licence or federal licences (like a passport).
• Liening Property: Placing a lien on property or homes owned by the payor.

It is critical to note that arrears are almost impossible to eliminate, as a declaration of bankruptcy does not discharge child support debt.
