Child & Spousal Support

Last updated: June 2026

Child and spousal support in Ontario are financial obligations that may arise after separation or divorce, intended to ensure children are properly supported and to address any economic disadvantage experienced by a spouse as a result of the relationship breakdown. Whether you're in Toronto, Markham, North York or elsewhere in Ontario, these legal principles apply province-wide.

Key Legal Points

Child support is governed by the Federal Child Support Guidelines

In most cases, child support in Ontario is calculated under the Federal Child Support Guidelines, based primarily on the paying parent's annual income, the number of children, province of residence, and the parenting arrangement (e.g., primary residence or shared parenting). This produces a "table amount," which courts generally follow.

High-income child support (income over $150,000)

For parents with annual income exceeding approximately $150,000, child support isn't strictly limited to the table amount. The table provides a starting point, but courts have discretion to order additional support above it — particularly where the child's standard of living during the relationship was significantly higher, or where the child has significant educational, medical, or extracurricular expenses. High-income cases are highly fact-specific and often require detailed financial disclosure and analysis.

Child support may include special or extraordinary expenses

In addition to monthly table support, parents may also share section 7 expenses, including:

Childcare costs
Medical and dental expenses not covered by insurance
Educational and post-secondary education costs
Extracurricular activities

These expenses are typically shared proportionally based on each parent's income.

Spousal support is not automatic, and is not always lifetime

A common misconception is that spousal support is always required after separation and automatically lasts for life. This isn't correct — spousal support is not automatic, and not every case results in entitlement. The court considers the length of the relationship, each spouse's role during it, the income difference between the parties, financial circumstances after separation, age and health, and the ability to become self-sufficient. Lifetime spousal support is generally limited to long-term relationships involving significant economic dependence, age-related limitations, or an ongoing inability to become self-sufficient.

Spousal Support Advisory Guidelines (SSAG)

Although not legislation, the Spousal Support Advisory Guidelines are widely used in Ontario courts as a reference, providing suggested ranges for the amount and duration of support. However, courts retain full discretion and may depart from the SSAG depending on fairness and the case's circumstances.

Imputed income (court-assigned income)

The court isn't required to accept the income reported on a tax return. If a party is intentionally underemployed, unemployed, or has reduced income to avoid support obligations — for example, voluntarily leaving employment without reasonable justification, paying themselves an artificially low salary through a corporation, or operating a business with discretionary income reporting — the court may "impute income" based on earning capacity or available evidence. Courts generally do not accept intentional income reduction aimed at avoiding support obligations, and where supported by evidence, may assign a higher income for support purposes.

Self-Employed and Corporate Income Cases Are More Complex

Support disputes involving self-employed individuals or business owners often require deeper financial analysis. The court may review corporate financial statements, business expenses and deductions, retained earnings, shareholder benefits, personal expenses paid through a corporation, and historical income patterns. In many cases, the income the court ultimately determines may differ from what was reported to the Canada Revenue Agency.

Frequently Asked Questions

How is child support calculated?

Child support is generally calculated using the Federal Child Support Guidelines, based primarily on the paying parent's income, number of children, and parenting arrangement.

Can common-law partners claim spousal support?

Yes. Common-law partners may be entitled to spousal support depending on factors such as the length of the relationship, financial dependence, and the economic consequences of the relationship breakdown.

What if my former spouse is hiding income?

The court takes financial disclosure obligations seriously. If a party is found to be underreporting or concealing income, the court may order further disclosure and may impute income based on available evidence — especially common in self-employment and corporate income cases.

Can child or spousal support be changed later?

Yes. Support may be varied if there is a material change in circumstances, such as income changes, job loss or career change, retirement, changes in parenting arrangements, or changes in a child's needs. A court order or formal agreement is typically required.

Is spousal support always required, and is it lifetime?

No. Spousal support is not automatic and is not always lifetime. It depends on the specific facts of the case, including income differences, length of relationship, and financial dependency.
