Quick Answer: How Are Child Support Payments Calculated in Ontario?

Ontario follows the Federal Child Support Guidelines. These guidelines basically look at two main things. First, how much the paying parent makes which is the gross annual income and second, how many kids need support. But of course, that’s not the whole story. Things like shared custody, special expenses like daycare, medical bills or even sports programs, as well as unique family situations can affect the final amount of the child support.

That’s where we come in. At Tailor Law, we help you figure out the right numbers, explain everything in plain language- no jargon, and stand by you to make sure the agreement is both fair and enforceable to both parties involved. 

Service Overview: Understanding Child Support Calculations

Child support calculations are a core part of family law in Ontario, designed to ensure children’s needs are met after a separation or divorce. The process is guided by the Federal Child Support Guidelines and the Ontario Family Law Act.

Why Child Support Calculations Matter

Child support is not just about the money. It’s about stability and fairness especially if your kids future depends on it.

  • Protects children’s financial security after a family change.
  • Reduces conflict with standardized, transparent calculations.

Frequently Asked Questions About Child Support Calculations in Ontario

1. How are child support amounts set in Ontario?

Child support is based on the Federal Child Support Guidelines, which use the paying parent’s gross income and number of children. Adjustments may be made for special expenses or unique circumstances.

2. What counts as income for child support?

Income includes salary, wages, bonuses, commissions, self-employment income, and certain benefits. If a parent is intentionally underemployed, the court may impute income.

3. Can child support be adjusted if my income changes?

Yes. A significant change in income or circumstances can justify a variation of the support order. Tailor Law can guide you through this process.

4. What are “special or extraordinary expenses”?

These include daycare, medical or dental costs not covered by insurance, and extracurricular activities. These are typically shared in proportion to each parent’s income.

5. How does shared custody affect child support?

If parents share physical custody (at least 40% of the time), the calculation may be adjusted to reflect each parent’s time and expenses.

6. How long does child support last?

Support usually continues until the child turns 18, or longer if they are in full-time education or unable to be self-supporting.

7. What if a parent refuses to provide financial disclosure?

The court can order disclosure and may impute income if a parent withholds information. Legal guidance is crucial in these cases.

8. Do I need a lawyer for child support calculations?

While you can use online calculators, a lawyer ensures all factors are considered and your agreement is enforceable.

9. How much does it cost to hire a child support lawyer?

Fees depend on case complexity. Tailor Law offers transparent, upfront pricing and payment plans. Your first consultation is free.

10. What if the other parent lives outside Ontario?

Child support orders can be enforced across Canada and internationally through reciprocal agreements.
