Yes, child support in Ontario can cover college and university expenses. Under the Divorce Act, R.S.C. 1985, c. 3, s. 2(1), a child enrolled in full-time post-secondary education remains a "child of the marriage" entitled to support, regardless of being over 18. Parents typically share tuition costs ($9,400-$49,800 annually) proportionate to their incomes under Section 7 of the Federal Child Support Guidelines. Courts apply the Farden factors to determine whether support should continue, and students are generally expected to contribute 25-50% of their own education costs through loans, grants, or part-time work.

How Ontario Law Treats Child Support for College Students
Child support for post-secondary education in Ontario continues beyond age 18 when the child remains dependent and enrolled in full-time studies at a recognized institution. The Divorce Act, R.S.C. 1985, c. 3, s. 2(1) defines a "child of the marriage" as someone who has not withdrawn from parental charge and is "unable, by reason of illness, disability or other cause, to withdraw from their charge or to obtain the necessaries of life." Canadian courts have consistently interpreted "other cause" to include pursuing post-secondary education, making college tuition divorce obligations enforceable in Ontario.
Two separate statutes govern these obligations depending on whether parents were married. The federal Divorce Act applies to divorcing spouses, while the Ontario Family Law Act, R.S.O. 1990, c. F.3, s. 31 governs unmarried or common-law parents. Under the Family Law Act, a child eligible for support includes any unmarried child who is either a minor (under 18) or enrolled in a full-time program of education.
There is no arbitrary age cutoff in Ontario. Courts have ordered child support college Ontario obligations for students as old as 22 or 23 while completing undergraduate degrees. However, support does not continue indefinitely. The child must demonstrate a clear educational plan, reasonable progress, and continued dependency on parental financial assistance.
Section 3 vs. Section 7: Understanding the Two Types of Support
Ontario child support consists of two distinct components that apply differently to post-secondary education expenses. Section 3 support (the Table Amount) covers basic monthly necessities like food, clothing, and shelter. Section 7 support covers "special or extraordinary expenses," which explicitly includes post-secondary education tuition and living expenses.
The Table Amount is calculated using the Federal Child Support Guidelines, which were comprehensively updated on October 1, 2025 — the first major revision since 2017. These tables determine the base monthly payment based on the paying parent's income and the number of children. For 2026, the income threshold starts at $16,000 annually (increased from $13,000 in 2017), meaning parents earning below this amount may have a zero Table Amount while still owing proportional Section 7 contributions.
Post-secondary education costs fall exclusively under Section 7. This means college tuition, university fees, residence costs, meal plans, textbooks, and reasonable living expenses are shared between parents in proportion to their respective incomes — not according to the Table Amount formula.
| Support Type | What It Covers | How It's Calculated |
|---|---|---|
| Section 3 (Table Amount) | Basic necessities (food, shelter, clothing) | Federal tables based on payor income |
| Section 7 (Special Expenses) | Tuition, living costs, textbooks, childcare | Proportionate to combined parental income |
How Section 7 Education Expenses Are Calculated
Section 7 expenses for post-secondary education are divided between parents in direct proportion to their respective incomes, creating a fair distribution based on ability to pay. If one parent earns $100,000 annually and the other earns $50,000, their combined income totals $150,000. The higher-earning parent pays 66.6% of qualifying education expenses, while the lower-earning parent covers 33.3%.
For example, if university costs total $20,000 per year (including tuition of $9,400, residence at $8,000, and a meal plan at $2,600), the parent earning $100,000 would pay approximately $13,320 annually, while the parent earning $50,000 would contribute $6,680. These amounts are in addition to any ongoing Table Amount support.
Section 7 expenses must satisfy a dual legal test before courts will order their payment. First, the expense must be necessary and in the child's best interests. Second, the expense must be reasonable given both parents' financial means and consistent with pre-separation family spending patterns. A court will not order a parent to contribute to a $50,000 private university program if the family's combined income is $80,000 and the child could attend a comparable public institution for $15,000.
The Farden Factors: How Courts Decide Adult Child Support
Ontario courts apply the Farden factors — established in Farden v. Farden, 1993 CanLII 2570 (BCSC) — to determine whether an adult child pursuing post-secondary education remains entitled to support. These seven factors guide judicial discretion but are not a rigid checklist. Courts weigh each factor according to the specific circumstances of the case.
The Farden factors include:
- Whether the child is enrolled in a full-time or part-time course of studies at a recognized institution
- Whether the child has applied for or is eligible for student loans, grants, bursaries, or other financial assistance
- Whether the child has a reasonable career plan or is attending school simply because they have nothing better to do
- The child's ability to contribute through summer or part-time employment
- The child's past academic performance and current success in their chosen program
- What educational plans the parents made during their relationship, including any savings or expectations
- Whether the child has unilaterally terminated the relationship with the parent from whom support is sought
Factor seven carries particular weight. If an adult child refuses to communicate with a paying parent or has cut off contact without justification, courts may reduce or terminate support obligations. However, courts distinguish between a child's legitimate estrangement due to parental misconduct and a child's unreasonable rejection of a parent.
Child Contribution Requirements: The One-Third Rule
Ontario courts expect adult children to contribute toward their own post-secondary education to the fullest extent reasonably possible. This principle reflects the understanding that education benefits the child directly, creating an obligation to share responsibility. Courts frequently apply what practitioners call the "one-third rule" — the child contributes approximately one-third of total costs through loans, grants, bursaries, scholarships, and employment income, with parents splitting the remaining two-thirds proportionate to their incomes.
The actual contribution expected varies based on family circumstances. Courts consider the child's realistic earning capacity during school, the availability of financial aid, the parents' respective incomes, and any educational savings plans (RESPs) established during the marriage. Higher-earning parents generally face reduced expectations for child contributions, as courts recognize that wealthy families traditionally fund education without requiring loans.
A child attending a $15,000-per-year program might be expected to contribute $5,000 through part-time work ($3,000-4,000), summer employment ($2,000-3,000), and student loans or grants. The remaining $10,000 would be divided between parents proportionate to income. If parents earn equally, each pays $5,000. If one parent earns twice the other's income, the higher-earner pays approximately $6,666 while the lower-earner pays $3,333.
Multiple Degrees and Graduate Studies
Parental support obligations may extend beyond an initial undergraduate degree when pursuing additional education represents a reasonable career path. Ontario courts have acknowledged that modern employment markets increasingly require advanced degrees, and parents may be obligated to contribute to law school, medical school, graduate programs, or professional certifications when such education connects logically to the child's established career trajectory.
However, support for subsequent degrees receives greater scrutiny. Courts examine whether the child demonstrated commitment during their first degree, whether the advanced program represents a natural progression, and whether the parents' financial circumstances can reasonably accommodate extended support. A child who struggled academically during their undergraduate years or who pursues an unrelated graduate degree faces a higher burden to justify continued parental support.
Support generally does not extend to children who delay post-secondary education indefinitely. An adult child who works for several years after high school and then decides to attend university may not qualify as a "child of the marriage" unless illness, disability, or another compelling circumstance prevented earlier enrollment. Courts distinguish between reasonable gap years (one to two years for work experience, travel, or personal growth) and indefinite postponement of educational goals.
How to Claim Post-Secondary Education Support
Parents seeking child support for college or university expenses can include these costs in their initial divorce or separation proceedings or seek a variation of an existing support order. The process requires documenting the child's enrollment, itemizing expected expenses, and demonstrating how costs should be shared proportionate to income.
Required documentation typically includes:
- Proof of enrollment (acceptance letter, registration confirmation)
- Tuition invoices from the institution
- Residence and meal plan costs
- Estimated textbook and supply expenses
- Both parents' current income tax returns (Notice of Assessment)
- Any RESP or education savings account statements
- Student loan or financial aid applications and awards
Filing fees for divorce applications in Ontario total $669, paid in two installments: $224 when filing the application and $445 when filing the Affidavit for Divorce. Joint applications cost $632. The federal divorce registry charges an additional $10 fee that cannot be waived. Parents receiving Ontario Works, ODSP, or meeting specific low-income thresholds may apply for a fee waiver certificate.
When Child Support for College Ends
Child support for post-secondary education typically terminates upon completion of the child's first undergraduate degree or equivalent credential. For a standard four-year bachelor's program, this usually means support continues until the child reaches age 22 or 23. However, there is no automatic termination, and the paying parent must apply to vary or end the support order.
Support may end earlier if the child:
- Withdraws from full-time studies without reasonable cause
- Fails to maintain adequate academic standing
- Obtains full-time employment and achieves financial independence
- Marries or enters a spousal relationship
- Refuses to communicate with or maintain a relationship with the paying parent
- Completes their program of study
Conversely, support may extend beyond the first degree when the child pursues professional school (law, medicine, dentistry) or graduate studies that represent a logical continuation of their undergraduate education. Courts examine whether the additional education is necessary for the child's chosen career and whether the parents can reasonably afford continued support.
Current Tuition Costs in Ontario (2026)
Understanding actual costs helps parents plan for post-secondary education expenses. After an eight-year provincial tuition freeze, Ontario institutions can now increase fees by up to 2% annually starting with the 2026-2027 academic year.
| Student Category | Annual Tuition Range | Notes |
|---|---|---|
| Domestic Undergraduate | $9,400-$14,000 | Varies by program; professional programs higher |
| Domestic Graduate | $8,000-$25,000 | MBA and professional degrees at premium |
| International Undergraduate | $42,000-$49,800 | Ontario has highest international fees nationally |
| International Graduate | $24,000-$28,600 | STEM and business programs at higher end |
Beyond tuition, parents should anticipate residence costs of $6,000-$12,000 annually, meal plans of $2,500-$5,000, textbooks and supplies of $1,000-$2,000, and personal expenses of $3,000-$5,000. Total annual costs for a domestic undergraduate living on campus range from $22,000 to $35,000 depending on location and program.
Practical Tips for Divorced Parents
Navigating child support for college requires clear communication and proper documentation regardless of how amicable the co-parenting relationship may be. Parents should maintain detailed records of all education-related expenses, keep copies of tuition invoices and payment confirmations, and document any communications regarding educational plans.
Consider including specific provisions in your separation agreement or divorce order that address post-secondary education obligations. A well-drafted agreement specifies how expenses will be shared, what constitutes qualifying expenses, how the child's contribution will be calculated, and what happens if circumstances change. Ambiguous agreements lead to expensive modification proceedings.
RESP (Registered Education Savings Plan) accounts established during the marriage require particular attention. Determine who controls the RESP, how withdrawals will be managed, and whether contributions should continue post-separation. RESP funds can significantly offset the Section 7 expenses that parents must otherwise share from current income.
