1. Introduction to Child Support in Ontario

 

Child support is a foundational element of family law in Ontario, ensuring that children’s financial needs are met following a separation or divorce. The law recognizes that both parents are responsible for supporting their children. The right to child support rests with the child, not the parent, and cannot be waived by either parent.

 

2. Who Pays Child Support?

 

In Ontario, the parent who has the child for less than 40% of the time (non-custodial parent) is generally required to pay child support to the parent with primary care. Child support obligations apply to biological parents, adoptive parents, and in some cases, step-parents or those who have acted as a parent.

 

Child support applies regardless of whether the parents were married, in a common-law relationship, or never lived together. The goal is to ensure the child maintains a standard of living similar to what they would have enjoyed if the family remained together.

 

3. How Child Support is Calculated

 

Ontario uses the Federal Child Support Guidelines, which set out a standardized approach for determining the base amount of support. The calculation is primarily based on:

 

– The gross annual income of the paying parent
– The number of children entitled to support
– The province or territory of residence

 

The government provides online child support tables to assist with these calculations.

 

Example:
If a parent earns $60,000 annually and has two children, the table will indicate the monthly amount payable, subject to adjustments for special circumstances.

 

4. Federal Child Support Guidelines Explained

 

The Federal Child Support Guidelines are designed to promote fairness, consistency, and predictability in child support orders. Key components include:

 

– Table Amounts: The basic monthly amount based on income and number of children.
– Special or Extraordinary Expenses (section 7 expenses): Additional costs not covered by the base amount, such as:
– Childcare
– Medical and dental insurance premiums
– Health-related expenses over $100/year
– Educational expenses
– Extracurricular activities

 

Section 7 expenses are shared proportionally based on each parent’s income.

 

5. Special or Extraordinary Expenses

 

These expenses extend beyond basic child support and require separate calculation and agreement or court order. Common examples include:

 

– Private school tuition
– Post-secondary education costs
– Tutoring for learning disabilities
– Competitive sports or arts programs

 

Both parents must contribute to these expenses in proportion to their incomes. Documentation and transparency are important—keep receipts and records for all extraordinary expenses.

 

6. When Child Support Ends

 

In Ontario, child support typically continues until the child turns 18. However, support may extend beyond 18 if:

 

– The child is enrolled in full-time education
– The child is unable to withdraw from parental control due to illness, disability, or other causes

 

Courts will consider the child’s circumstances, level of independence, and ability to support themselves when determining the duration of support.

 

7. Changing Child Support Orders

 

Life circumstances often change after a child support order is made. If your financial situation, employment status, or custody arrangement changes, you may apply to the court to vary (change) the child support order. Reasons for variation may include:

 

– Significant increase or decrease in income
– Change in parenting time/custody arrangements
– Change in the child’s needs (e.g., medical or educational expenses)
– The child reaching the age of majority or completing education

 

To request a variation, you must provide updated financial disclosure and evidence of the change in circumstances.

 

8. Enforcing Child Support in Ontario

 

The Family Responsibility Office (FRO) is the government agency responsible for enforcing child support orders and agreements in Ontario. If payments are missed or delayed, FRO has several enforcement options, such as:

 

– Garnishing wages or bank accounts
– Suspending driver’s licenses or passports
– Reporting to credit bureaus
– Seizing assets or tax refunds

 

If you are owed child support or facing enforcement action, it is crucial to seek legal advice promptly to protect your interests.

 

9. Child Support in Shared or Split Custody Arrangements

 

Child support calculations become more complex when parents share or split custody (each parent has the child at least 40% of the time). In these cases, the amount is determined by:

 

– Calculating what each parent would owe if the other were the primary caregiver
– Offsetting the amounts, with the higher-income parent paying the difference to the other

 

This approach ensures fairness and reflects the shared responsibilities of both parents.

 

10. Tax Implications of Child Support

 

In Ontario, child support payments are generally:

 

– Not tax-deductible for the paying parent
– Not considered taxable income for the receiving parent

 

However, certain special or extraordinary expenses, such as childcare, may have tax implications. Consult a family law lawyer or tax advisor for specific guidance.

 

11. Common Challenges and Solutions

 

a) Non-Disclosure of Income
Sometimes, a parent may underreport income or fail to provide full disclosure. The court can impute income if it finds that a parent is intentionally unemployed or underemployed.

 

b) Retroactive Child Support
Courts may order retroactive payments if a parent failed to pay appropriate support in the past.

 

c) International and Interprovincial Issues
If one parent lives outside Ontario or Canada, child support orders can still be enforced through reciprocal agreements.

14. Frequently Asked Questions (FAQs)

Can we agree to waive child support?

No. Child support is the right of the child and cannot be waived by parents.

 

What if the paying parent loses their job?

The paying parent must apply to the court or FRO to change the order. Simply stopping payments can lead to enforcement actions.

 

Does remarriage or new children affect child support?

Remarriage does not end child support obligations. However, the court may consider new financial responsibilities in rare cases.

 

Is child support different for adult children with disabilities?

Yes. Support may continue indefinitely if the child is unable to become independent due to disability.
