Quebec parents must share health insurance and medical expenses for their children proportionally based on disposable income under the Quebec Model for the Determination of Child Support Payments. Basic child support tables do not include medical costs—health-related expenses are calculated separately as "special expenses" under Section 9 of the Regulation (C-25.01, r. 0.4). A parent earning 60% of the combined disposable income pays 60% of all uncovered medical costs, from orthodontics averaging $5,500 to $7,500 to therapy sessions at $150 to $200 per hour.

How Quebec Allocates Health Insurance Costs in Child Support
Quebec allocates health insurance premiums and medical expenses as special expenses shared proportionally between parents based on their respective disposable incomes. Under Civil Code of Quebec, art. 585, both parents owe a duty of support to their children in proportion to their respective means. The basic parental contribution table covers food, clothing, shelter, and recreation but excludes health insurance premiums, prescription drug costs, and extraordinary medical expenses. Parents must calculate these costs separately using Schedule I of the Child Support Determination Form.
The Quebec Model differs fundamentally from the Federal Child Support Guidelines used in other provinces. Quebec calculates support based on combined disposable incomes of both parents rather than primarily the paying parent's income. This income-shares approach means a parent earning $80,000 annually when combined income totals $120,000 would pay approximately 67% of all special expenses including health insurance premiums attributable to the children.
Private health insurance premiums covering children are added to the basic parental contribution. If one parent carries family coverage through employment costing $3,600 annually, with $1,200 attributable to dependent children, that $1,200 becomes a special expense. Both parents share this cost proportionally—if income shares are 60/40, the parent without coverage reimburses $720 annually to the parent paying the premiums.
RAMQ Coverage Rules for Children After Separation
RAMQ (Régie de l'assurance maladie du Québec) provides universal health coverage for all Quebec residents including children of separated or divorced parents. Quebec's public health insurance covers medically necessary services including physician visits, hospital stays, and diagnostic testing at no direct cost. However, RAMQ does not cover prescription drugs, dental care, vision care, or paramedical services—these require either private insurance or separate payment.
Quebec mandates prescription drug coverage for all residents. Children must have drug coverage through either a parent's private group plan or the RAMQ public drug insurance plan. The priority order for children's drug coverage follows specific rules: first, the private plan of the parent with primary parenting time; second, the other parent's private plan if the primary parent lacks private coverage; third, the RAMQ public plan only when neither parent has private coverage available.
The RAMQ public drug plan costs $0 to $766 annually per adult depending on income, with a monthly deductible of approximately $24.60 and co-insurance of 34.6% for the 2025-2026 period. Children under 18 and full-time students under 25 living with a parent pay no premium for public plan coverage. Parents separating must notify RAMQ of their change in civil status within 31 days to ensure children's coverage documentation goes to the correct address.
Special Expenses: Medical Costs Beyond Basic Support
Special expenses under Section 9 of the Regulation (C-25.01, r. 0.4) include all health-related costs not covered by provincial health insurance or private insurance plans. These expenses are added to the basic parental contribution and shared proportionally based on each parent's share of combined disposable income. Typical special expenses include orthodontic treatment averaging $5,500 to $7,500, psychological services at $150 to $200 per session, speech therapy, physiotherapy, prescription medications, vision care including glasses and contact lenses, and dental work beyond basic coverage.
Parents must include special expenses on Schedule I of the Child Support Determination Form. The Quebec child support calculator automatically divides these costs proportionally once entered. A parent contributing 55% of combined disposable income pays 55% of all special expenses in addition to their 55% share of the basic parental contribution. This can increase total child support obligations by 30% to 50% above the basic table amount depending on the number and nature of expenses.
Court approval for special expenses requires demonstrating the expense is reasonable considering the family's financial circumstances and consistent with the child's established needs. Courts have denied claims for special expenses when one parent incurred them without the other's consent or when the expense exceeded the family's financial capacity. Parents should discuss and agree on significant medical expenses before incurring them.
| Special Expense Type | Typical Annual Cost | Sharing Method |
|---|---|---|
| Orthodontics | $5,500 - $7,500 total | Proportional to income |
| Psychological therapy | $7,800 - $10,400 (weekly) | Proportional to income |
| Private drug plan premium | $1,200 - $3,600 | Proportional to income |
| Vision care (glasses) | $300 - $600 | Proportional to income |
| Dental (beyond coverage) | $500 - $2,000 | Proportional to income |
| Speech therapy | $3,900 - $7,800 | Proportional to income |
Calculating Health Insurance Contributions
Quebec child support calculations use a four-step process for determining each parent's share of health insurance and medical expenses. First, calculate each parent's disposable income by subtracting the basic deduction of $13,575 (2026 indexed amount) and mandatory deductions from gross income. Second, determine combined disposable income by adding both parents' disposable incomes. Third, calculate each parent's percentage share by dividing their individual disposable income by the combined total. Fourth, multiply each special expense by each parent's percentage to determine their contribution.
For example, consider parents with disposable incomes of $45,000 and $30,000 respectively. Combined disposable income equals $75,000. Parent A's share is 60% ($45,000 / $75,000), and Parent B's share is 40% ($30,000 / $75,000). If annual special expenses total $4,800 including $1,800 in health insurance premiums, $1,500 in uncovered dental work, and $1,500 in therapy sessions, Parent A pays $2,880 (60%) and Parent B pays $1,920 (40%).
The 2026 contribution tables were published January 29, 2026, reflecting a 3.2% indexation factor based on the Quebec Pension Plan annual pension index. Parents can access current tables through the Quebec government website. The basic deduction increased from $13,150 in 2025 to $13,575 in 2026, reducing disposable income calculations slightly for both parents.
Private Health Insurance Priority Rules
Quebec law establishes a priority order for children's private health insurance coverage when parents separate. The private plan of the parent with primary parenting time provides coverage first. If that parent has no private plan available, the other parent's private plan applies. Only when neither parent has access to private coverage does the child default to the RAMQ public drug plan. This hierarchy ensures children maintain continuous coverage while optimizing the use of employer-sponsored benefits that often provide superior coverage to public alternatives.
Parenting agreements should specify which parent's plan provides primary coverage for the children and address how uncovered medical expenses will be handled. Courts recommend including provisions for: notification requirements when one parent's coverage changes; procedures for submitting claims to both plans when coordination of benefits applies; deadlines for reimbursing the other parent for their share of out-of-pocket expenses; and protocols for agreeing on major medical decisions involving significant cost.
When both parents have private coverage, coordination of benefits rules determine payment order. The plan of the parent with the earlier birthday in the calendar year typically pays first for the children's claims. The second plan then covers remaining eligible expenses up to its limits. Parents should provide each other with insurance cards and plan documentation to facilitate claims submission.
Federal Guidelines vs. Quebec Model for Medical Expenses
Quebec applies its provincial model when both parents reside in Quebec, even in divorce proceedings under federal jurisdiction. The Federal Child Support Guidelines apply only when one parent lives outside Quebec. This distinction significantly affects how medical expenses are calculated and allocated.
Under Federal Child Support Guidelines, Section 7, special expenses include "that portion of the medical and dental insurance premiums attributable to the child" and "health-related expenses that exceed insurance reimbursement by at least $100 annually." The federal model lists specific qualifying expenses more narrowly than Quebec's broader approach. Federal guidelines also require expenses to be "reasonable" and "necessary," adding subjective criteria the Quebec model avoids through its proportional sharing framework.
Parents relocating between Quebec and other provinces should understand which model will apply. If both parents move to Ontario, federal guidelines replace the Quebec model entirely. If one parent remains in Quebec while the other moves to another province, the court with jurisdiction determines which model applies based on factors including where the children primarily reside and which parent initiated proceedings.
| Factor | Quebec Model | Federal Guidelines |
|---|---|---|
| Income basis | Both parents' disposable income | Primarily paying parent's income |
| Medical expense threshold | No minimum threshold | $100 annual minimum |
| Expense sharing | Proportional to income shares | Proportional to income |
| Insurance premiums | Automatically included | Specifically listed |
| Basic deduction | $13,575 per parent (2026) | None |
| Extraordinary expense definition | Broad interpretation | Narrow statutory list |
Enforcing Health Insurance Obligations
Quebec enforces health insurance obligations through Revenu Québec's Support Payment Collection Program (Programme de perception des pensions alimentaires). When a court order or agreement requires one parent to maintain insurance for the children or pay a share of medical expenses, Revenu Québec can enforce these obligations alongside regular support payments. Failure to maintain required insurance coverage or pay allocated medical expenses can result in wage garnishment, tax refund interception, and credit bureau reporting.
Parents seeking enforcement must document the obligation clearly in their court order or written agreement. Specific language should state which parent maintains insurance, how premiums are shared, the deadline for reimbursing uncovered expenses, and consequences for non-compliance. Vague provisions like "parents shall share medical expenses" create enforcement difficulties—courts prefer specific percentages tied to income shares calculated at the time of the order.
SARPA (Service administratif de rajustement des pensions alimentaires pour enfants) handles administrative recalculations of child support for $57.25 when modifications are based solely on income changes. However, changes to special expense allocations typically require court modification unless parents agree in writing. Annual income verification allows proportional shares to adjust without court involvement, but adding new categories of special expenses requires either agreement or judicial order.
Modifying Health Insurance Arrangements
Parents can modify health insurance arrangements when circumstances change significantly. Common triggers include: one parent gaining or losing employer-sponsored coverage; children developing new medical needs requiring ongoing treatment; significant income changes affecting proportional shares; or relocation affecting which provincial rules apply. Quebec courts consider whether the change is substantial, ongoing, and unforeseeable at the time of the original order.
Administrative recalculation through SARPA addresses income-based changes efficiently. For a $57.25 fee, SARPA recalculates child support including proportional expense shares based on updated income information. This process avoids court costs for straightforward modifications. However, disputes about whether expenses qualify as special expenses or whether proposed treatments are reasonable require court determination.
Parents should review health insurance arrangements annually as part of the required financial disclosure under Quebec family law. Civil Code of Quebec, art. 587.2 permits courts to increase or reduce support levels when special circumstances cause undue hardship, including significant medical expense changes. A child's diagnosis with a chronic condition requiring $12,000 annually in uncovered treatment would constitute grounds for modification.
Adult Children: Medical Support After Age 18
Quebec's parental support obligation continues beyond age 18 for children unable to support themselves. Under Civil Code of Quebec, art. 585, courts consistently interpret this to include full-time students pursuing higher education. Support including health expense allocation typically continues through completion of a first undergraduate degree, usually until age 22 to 24. Medical expenses for adult children attending CEGEP or university remain subject to proportional sharing.
The RAMQ public drug plan covers full-time students aged 18 to 25 who are single and living with a parent at no premium cost. However, many employer plans limit dependent coverage to age 21 or age 25 for full-time students. Parents should verify coverage continuation rules and plan accordingly for transition periods when adult children may need to obtain their own coverage.
Parenting agreements should address adult child medical coverage specifically. Provisions might include: maintaining coverage until age 25 or completion of first undergraduate degree; allocating COBRA-equivalent continuation costs if private coverage lapses; and specifying whether post-secondary education medical plan fees constitute shareable special expenses.
Documentation and Record-Keeping Requirements
Quebec parents must maintain comprehensive records of all health insurance and medical expenses to support child support calculations and potential modifications. Required documentation includes: annual statements of health insurance premiums showing amounts attributable to dependent children; receipts for all uncovered medical expenses; explanation of benefits statements from insurance providers; and cancelled checks or electronic payment confirmations for expense reimbursements.
The Civil Code requires parents to exchange financial information annually, including income statements and tax documents. This disclosure obligation extends to health insurance documentation. Parents should provide updated insurance cards, coverage summaries, and premium statements each year. Failure to disclose insurance changes affecting the children may constitute grounds for modifying support obligations retroactively.
For special expense claims, parents should document: the medical necessity of the treatment; prior consultation with the other parent when possible; the total cost and insurance coverage breakdown; and the calculation of each parent's proportional share. Courts favor parents who maintain organized records and communicate proactively about significant medical expenses before incurring them.
