How is child support calculated in Ontario?▼
Child support in Ontario is calculated using the Federal Child Support Guidelines tables. The amount is based on the payor's gross annual income (line 15000 of your tax return) and the number of children. For example, a parent earning $60,000/year with 2 children would pay approximately $892/month in base support.
What income is used for child support?▼
Child support uses gross annual income, which is line 15000 on your tax return (total income before deductions). This includes employment income, self-employment income, investment income, rental income, and other sources. Adjustments may be made for self-employment, non-recurring income, or undisclosed income.
What are Section 7 special expenses?▼
Section 7 expenses are costs beyond basic child support that parents typically share in proportion to their incomes. These include: childcare expenses, medical/dental premiums and expenses not covered by insurance, extraordinary extracurricular activities, post-secondary education costs, and primary residence expenses for adult children.
How does shared custody affect child support?▼
In shared custody arrangements (where each parent has the child at least 40% of the time), both parents' incomes are considered. The court may "set off" the two table amounts against each other, meaning the higher-income parent pays the difference. Other factors like actual costs and the child's needs are also considered.
