How Child Support Works in Ontario

Ontario uses the Federal Child Support Guidelines for divorce proceedings and has adopted equivalent provincial guidelines under the Family Law Act for unmarried parents. The Family Responsibility Office (FRO) enforces support orders. Ontario's Form 13 and Form 13.1 financial statements are required in most support cases.

Divorcepath calculates Ontario child support using the current Federal Child Support Tables, automatically applying Ontario provincial tax rates, credits, and government benefits to determine accurate support amounts and net income for each party.

Frequently Asked Questions

Common questions about child support in Ontario.

How is child support calculated in Ontario?
Child support in Ontario is calculated using the Federal Child Support Guidelines. The base amount (table amount) is determined by the paying parent's gross annual income and the number of children. Additional amounts may be ordered for special or extraordinary expenses under section 7 of the Guidelines, which are shared proportionally to each parent's income. Divorcepath automates these calculations and applies Ontario's provincial tax rates to determine the net financial impact.
Where do I file for child support in Ontario?
Family law matters in Ontario can be heard in the Superior Court of Justice or, for some matters, the Ontario Court of Justice. The Family Responsibility Office (FRO) handles enforcement of all support orders.
What forms do I need for child support in Ontario?
In Ontario, you will typically need a financial statement (Form 13 (Financial Statement — Support), Form 13.1 (Financial Statement — Property/Support)) and an application or motion for child support. Divorcepath can help auto-populate these forms with data from your support calculation, reducing manual data entry and the risk of errors.
What if we have shared custody in Ontario?
When a child spends at least 40% of the time with each parent, this is considered shared custody under the Federal Child Support Guidelines. In shared custody situations, child support is calculated using a set-off approach: both parents' table amounts are calculated, and the difference is paid by the higher-income parent. Divorcepath's calculator handles shared custody calculations automatically for Ontario families.
How are special expenses (section 7) handled?
Special or extraordinary expenses (childcare, medical/dental insurance premiums, health-related expenses, education, extracurricular activities, and post-secondary education) are shared between parents in proportion to their incomes, after accounting for any tax credits or deductions related to the expense. Divorcepath automatically calculates the net cost and proportional sharing for Ontario families, including Ontario-specific tax credits.
Is the calculator accurate for Ontario?
Yes. Divorcepath uses the current Federal Child Support Tables and applies Ontario's specific provincial tax rates, credits, and benefit calculations. The calculator is trusted by over 500 Canadian law firms and has been used by more than 300,000 Canadians. Reports generated by Divorcepath are accepted in Ontario courts.
Do I need a lawyer to calculate child support?
You do not need a lawyer to calculate child support. Divorcepath provides the same professional-grade calculations used by family lawyers across Canada. However, for complex situations involving income disputes, undue hardship claims, or high-conflict cases, consulting a Ontario family lawyer is recommended. Divorcepath provides legal information, not legal advice.
