Ontario Divorce Financial Planning: Advisor Guide to Child Support and Tuition

When clients separate, their financial landscape undergoes a dramatic shift. As a trusted advisor, you play a critical role in helping your clients navigate complex issues that impact wealth, tax planning, and long-term financial stability. One question often arises: 

Who pays for child support, private school tuition, or extracurricular activities after separation? 

Let’s break down what you need to know. 

Child Support and Special Expenses 

Under Ontario’s Child Support Guidelines, certain costs — called Section 7 special or extraordinary expenses — may be shared between parents in proportion to their incomes. These often include: 

• Private school tuition 

• Childcare costs 

• Extracurricular activities (sports, arts programs, etc.) 

Scenario: Proportional Sharing of Private School Tuition

• Annual Tuition: $20,000 

• Parent A’s Income: $120,000 

• Parent B’s Income: $80,000 

• Combined Income: $200,000 

Step 1: Calculate Each Parent’s Income Share

• Parent A: $120,000 ÷ $200,000 = 60% 

• Parent B: $80,000 ÷ $200,000 = 40% 

Step 2: Apply Proportional Split to Tuition 

• Parent A pays: $20,000 × 60% = $12,000 

• Parent B pays: $20,000 × 40% = $8,000 

Key Factors Courts Consider 

• Pre-separation lifestyle: If the child attended private school or participated in activities before separation, courts often aim to maintain continuity — provided it’s financially reasonable. 

• Type of support paid: Regular child and spousal support obligations influence how additional expenses are allocated. 

• Reasonableness: Courts assess whether the expense is necessary and proportionate to the family’s financial circumstances. 

• Income-based cost sharing: Costs are typically split based on each parent’s income, not equally. 

How Advisors Can Assist Their Clients 

1. Review Client’s Historical Spending on Education and Activities 

Go beyond a glance at tuition invoices. Provide clients with an analysis of multi-year patterns for private school, extracurricular programs, tutoring, and childcare. This helps establish a baseline for what courts may consider “reasonable” and supports negotiations. Include any prepaid commitments (e.g., annual tuition or seasonal sports fees) that could affect cash flow. 

2. Model Affordability Scenarios Post-Separation 

Provide your clients with projections that factor in: 

• New household budgets (two homes instead of one). 

• Support obligations (child and spousal support). 

• Tax impacts (loss of certain credits or deductions). 

Provide best-case and worst-case scenarios to show whether continuing private school or activities is sustainable. This positions you as a strategic advisor, not just a compliance resource. 

3. Track and Document Pre-Separation Costs for Legal Negotiations 

Accurate records strengthen your client’s position in mediation or arbitration. Compile receipts, bank statements, and invoices for education and extracurriculars. Organize them by category and date to demonstrate historical spending patterns. Courts often rely on this evidence when determining proportional contributions. 

4. Flag Potential Tax Implications 

Don’t overlook the tax side: 

• Childcare deductions: Certain expenses may qualify, reducing taxable income. 

• RESP contributions: Divorce can disrupt education savings plans; advise on ownership changes and contribution strategies. 

• Capital gains or liquidity planning: If assets need to be sold to fund settlements, anticipate tax consequences early. 

5. Prepare Valuations for Businesses, Investments, and Pensions 

Business valuation is often one of the most complex aspects of divorce financial planning. Advisors should provide clear, defensible valuations for private companies, real estate holdings, and pension entitlements. Courts and mediators rely on these figures to determine equitable division.
