In Ontario, child support does not automatically end when a child turns 18 or moves into a university dorm room. They are still considered a “child of the marriage” if pursuing full-time education. However, parents often modify the base monthly support amount to reflect the months the child actually lives at home, while splitting tuition and dorm costs as Section 7 expenses.
Sending a child off to university or college is a proud milestone for any parent. Whether they are moving from a family home in Mississauga to a student residence at Western University in London, or heading to Ottawa for their undergraduate degree, the transition brings significant financial changes. Many parents mistakenly believe that once a child turns 18 and moves out for school, the legal obligation to pay child support simply vanishes. 📚
Under Child Custody & Support laws in Ontario, this is generally not true. Both the federal Divorce Act and the provincial Family Law Act define a dependent child as one who is unable to withdraw from parental charge, which strongly includes pursuing their first post-secondary degree. 📝 However, the way child support is calculated shifts dramatically when the child no longer lives in the primary parent’s house full-time, making it crucial to understand how to legally adjust your payments.
Step-by-Step Process for Adjusting University Support
Adjusting support for a university student requires a collaborative approach to budgeting. You cannot unilaterally stop paying your monthly support just because September rolls around. Instead, you must recalculate the expenses based on the child’s new living situation. Most families in Ontario navigate this transition using the following steps. 📋
Step 1: Confirming the Child’s Dependent Status
First, verify that the child remains a dependent under the law. Typically, a child completing their first undergraduate degree or diploma on a full-time basis qualifies for continued support. 👀 Parents should ask to see the child’s official university enrollment letter and their course schedule to ensure they are taking a full course load.
Step 2: Calculating Section 7 Extraordinary Expenses
University costs are classified as “Section 7 Extraordinary Expenses.” You must calculate the total cost of tuition, textbooks, mandatory student fees, and the cost of the dorm room and meal plan. 💰 Crucially, before parents split this total (usually proportionate to their incomes), they must subtract any grants, scholarships, or expected student contributions (like summer job savings) and potentially OSAP (Ontario Student Assistance Program) funding.
Step 3: Adjusting the Base Table Amount
Because the child is living in a dorm for roughly eight months of the year, paying the full base monthly table amount to the other parent is often no longer appropriate. Generally, family law in Ontario allows parents to adjust this. 📅 A common solution is that the paying parent only pays the standard monthly table amount during the four summer months when the child moves back into the primary residence.
Step 4: Formalizing the New Agreement
Once you have agreed on the new numbers, you must formalize the change. Do not just rely on a verbal agreement. Your family lawyer should draft a Consent Dispute Resolution agreement or you must file a formal “Motion to Change” at the Superior Court of Justice. 💳 If your support is managed by the Family Responsibility Office (FRO), they will continue to garnish your wages at the old rate until they receive the updated court order.
How Much Will Post-Secondary Support Cost?
Funding a university education in Ontario is expensive, and parents are expected to contribute based on their financial capacity. Alongside the actual tuition and dorm costs, legal and mediation fees may be required to formally update your support arrangements. Here are estimated legal and educational costs in CAD as of May 2026: 💸
- Average Ontario Tuition & Dorms: Typically ranges from $15,000 to $25,000 CAD per year, shared proportionately between parents after student contributions.
- Court Filing Fees: Filing a Motion to Change on consent costs around $181 CAD.
- Family Mediation Services: If parents disagree on what to pay, a private mediator usually charges $150 to $400 CAD per hour.
- Family Lawyer Fees: Having a lawyer draft an updated support agreement generally costs between $1,500 and $3,500 CAD.
| Expense Type | Who is Responsible? | How it is Shared |
|---|---|---|
| University Tuition & Books | Parents & Child | Proportionate to Parents’ Incomes (after child’s contribution) |
| Dorm Room & Meal Plan | Parents & Child | Proportionate to Incomes (often replaces base child support for those months) |
| Base Table Support (Summer) | Paying Parent | Paid 100% to the parent whose home the child lives in during summer |
How Long Does the Modification Process Take?
You should ideally begin negotiating post-secondary support changes the spring before the child leaves for university. If both parents agree on the numbers, drafting a consent order and having it signed by a judge takes approximately 4 to 8 weeks. 🕑 If parents are in dispute over whether the child should take out OSAP loans or which university is too expensive, a contested Motion to Change can take 4 to 8 months to resolve in the Ontario family court system.
Frequently Asked Questions (FAQ)
Is the child expected to contribute to their own university costs?
Yes. Ontario family courts generally expect an adult child to contribute to their own education through summer employment, part-time jobs, student loans, or scholarships. Parents are typically only required to split the remaining shortfall.
What if we saved money in an RESP?
Funds saved in a Registered Education Savings Plan (RESP) are usually applied to the tuition and dorm costs first. Once the RESP funds for that academic year are depleted, the parents then split the remaining balance based on their proportionate incomes.
Do I have to pay support if my child takes a gap year?
If the child takes a gap year after high school, is over 18, and is working full-time instead of attending school, they are generally no longer considered a dependent. Child support may be temporarily suspended or terminated, though it could be reinstated if they return to school full-time.
Can the child support be paid directly to the university student?
Yes. Under the guidelines, if a child is over 18 and living away from home, the court has the discretion to order that child support and Section 7 contributions be paid directly into the student’s own bank account rather than to the other parent.
