Updated April 2026." --- # The Child Support Payment Regulations and Tables: What They Are and How They Apply in Quebec # The _Child Support Payment Regulations and Tables_: What They Are and How They Apply in Quebec --- Quebec calculates child support differently from every other province in Canada. The [_Child Support Payment Regulations and Tables_](https://canlii.ca/t/10pq) (CQLR c C-25.01, r 0.4) establish a provincial model that considers both parents' incomes — not just the paying parent's — to determine what each parent owes toward the cost of raising their child. This page explains how that model works, how it differs from the federal _Child Support Guidelines_, and what Quebec's rules mean if you are navigating a separation, divorce, or child support dispute. --- ## What Are the _Child Support Payment Regulations and Tables_? The [_Child Support Payment Regulations and Tables_](https://canlii.ca/t/10pq) is a Quebec provincial regulation enacted under the _Code of Civil Procedure_ (CQLR c C-25.01). It establishes the legal framework and mathematical model that Quebec courts, mediators, and notaries use to calculate [child support](https://goldwaterdroit.com/en/services/child-spousal-support) — referred to in French as _l'obligation alimentaire envers l'enfant_. The regulation applies to most families in Quebec, whether parents were married, in a civil union, or in a _de facto_ (common-law) relationship. Quebec's model is what lawyers call an **income-shares model**. Rather than fixing a support amount based only on what the paying parent earns, the Quebec model combines both parents' gross annual incomes to determine the **basic parental contribution** (_contribution parentale de base_) — the total cost of raising the children attributable to both parents together. It then divides that contribution between them proportionally. Each parent pays their share in proportion to their income. This stands in sharp contrast to the federal [_Child Support Guidelines_](https://canlii.ca/t/10pq) (SOR/97-175), which govern other provinces and set child support based solely on the paying parent's gross income and province of residence. Quebec's approach treats child-rearing as a shared financial responsibility, not a one-directional transfer payment. > 💡 **Did you know?** Quebec was the first Canadian province to adopt an income-shares model for child support. When the federal _Child Support Guidelines_ came into force in 1997, the federal government formally recognized Quebec's distinct model as a valid alternative — embedding it in the definition of "applicable guidelines" under the federal framework. This means Quebec's provincial tables apply even in divorce proceedings under the _Divorce Act_, a formal accommodation of Quebec's legal distinctiveness that remains in place today. --- ## The _Child Support Payment Regulations and Tables_ in Quebec Context Quebec's child support regime is entirely provincial in origin, built into the province's civil procedure framework since the early 1990s and enacted under the authority of the _Code of Civil Procedure_. It applies across the province to virtually all parents, regardless of their marital status at the time of separation. **If you are married (or were married) and divorcing:** The federal [_Divorce Act_](https://canlii.ca/t/7vbw) (RSC 1985, c 3 (2nd Supp)) is the source of your support obligations. However, Quebec has been formally designated as a province with its own recognized child support guidelines, meaning that Quebec courts apply the provincial _Child Support Payment Regulations and Tables_ — not the federal tables — when calculating support for divorcing spouses in Quebec. **If you are not married:** The _Civil Code of Québec_ and the _Code of Civil Procedure_ govern your obligations, and the _Child Support Payment Regulations and Tables_ apply directly. _De facto_ spouses — common-law partners — have no mutual support obligations to each other in Quebec, but both parents carry equal legal obligations to support their children regardless of whether they were ever married. This dual applicability — to both married and unmarried parents — is one of the most important features of Quebec's system. The same tables and the same formula apply regardless of marital status. Who the parents were to each other affects spousal support; it does not affect child support. > 💡 **Did you know?** Quebec's income-shares model is actually closer to the approach used in most U.S. states than to the models used in other Canadian provinces. Most Canadian provinces use a payor-only model derived from the federal guidelines. Quebec's decision to adopt an income-shares approach reflects a distinct philosophical stance: both parents bear the cost of raising their children proportionally to their means, and neither is exempted from that responsibility simply because they are the recipient parent. --- ## What the _Child Support Payment Regulations and Tables_ Govern ### The Basic Parental Contribution The foundation of Quebec's child support calculation is the **basic parental contribution** (_contribution parentale de base_). This is the total amount that both parents together are deemed responsible for contributing to the cost of raising their children. The regulation's tables set out the basic parental contribution as a function of two variables: the parents' **combined gross annual income** and the **number of children** for whom support is being calculated. The calculation proceeds in steps: 1. Each parent's gross annual income is determined — including employment income, self-employment income, investment income, and other sources specified in the regulation. 2. The two incomes are combined. 3. The applicable table is consulted to identify the basic parental contribution for that combined income and number of children. 4. Each parent's share is calculated proportionally: a parent earning 60% of the combined income contributes 60% of the basic parental contribution. 5. The net support payable is the difference between the two proportional shares — typically, the higher-income parent pays their share minus the lower-income parent's share. > ⚠️ Determining "income" under the _Child Support Payment Regulations and Tables_ is not always as simple as reading a T4 slip. The regulation contains specific rules for attributing income to self-employed parents, shareholders in closely held corporations, and parents who have voluntarily reduced their earnings. Courts may **impute income** — that is, assign an income figure higher than what the parent actually declared — where they find that a parent is deliberately underemployed or has structured their financial affairs to minimize disclosed earnings. Income attribution is one of the most frequently litigated aspects of child support proceedings in Quebec. ### The Contribution Tables The [Quebec government's contribution tables](https://www.quebec.ca/en/family-and-support-for-individuals/separation-divorce/children-responsibility/child-support/contribution-tables) set out the basic parental contribution for combined incomes up to a specified ceiling. The tables are organized by number of children (one through five or more) and step through combined parental income in increments, providing a predictable amount for the vast majority of families. Where combined parental income exceeds the ceiling set in the tables, the regulation does not fix a specific amount. Courts have discretion to determine appropriate support based on the children's actual needs and the parents' demonstrated capacity to pay. This discretionary zone has been the subject of significant Quebec jurisprudence. > ⚠️ The contribution tables have a ceiling — and above that ceiling, there is no formula. Courts exercise judicial discretion, which means that evidence about the children's actual lifestyle and the paying parent's genuine financial capacity becomes central. This is not a minor edge case; it applies to a meaningful number of families in Quebec involving high earners or complex financial structures. In these cases, the outcome depends heavily on how evidence is marshalled and presented. Goldwater Droit has been at the forefront of Quebec's jurisprudence on guideline departures in high net worth cases. In _A v. B_, 2006 QCCS 2850 (CanLII), the firm obtained what was at the time the largest child support award in Quebec history, persuading the Superior Court to depart from the provincial tables given the extraordinary wealth of the paying parent. Drawing on detailed financial evidence and comparative jurisprudence from other jurisdictions, the firm demonstrated that guideline amounts would not reflect the children's genuine needs or the parent's true capacity. The Court adopted a contextual approach and ordered an amount commensurate with the family's actual circumstances. That decision continues to guide Quebec courts when determining support in cases involving very high income or complex financial structures. ### Shared Custody Arrangements When parents share custody — **garde partagée** — the basic calculation is adjusted to reflect the direct expenditures each parent makes while the child is in their care. Shared custody in Quebec is generally recognized when each parent has the child for at least 40% of the time on an annual basis. In a shared custody arrangement, each parent is credited for the direct costs they bear while the child is with them. The net support payable is adjusted downward to avoid double-counting — but it is not eliminated. Where there is significant income disparity between parents, the higher-income parent will typically still owe a net payment to the lower-income parent. > ⚠️ Shared custody does not automatically mean no child support is payable. Even in a strictly equal time-sharing arrangement, substantial income inequality will result in the higher-earning parent paying an amount to the lower-earning parent. The shared custody adjustment reduces the obligation; it does not erase the underlying proportional responsibility. In 2019, Goldwater Droit obtained a judgment increasing child support in a shared custody arrangement marked by sharp economic inequality. In _Droit de la famille — 191664_, 2019 QCCS 3479, the father maintained a multimillion-dollar lifestyle while the mother faced debt and limited income. The Superior Court found that strict application of the guidelines created undue hardship and ordered an additional $12,000 per year to equalize the children's quality of life across both homes. The case reaffirmed that Quebec courts may depart from guideline formulas where fairness and the children's best interests require it. ### Special and Extraordinary Expenses Beyond the basic parental contribution, the _Child Support Payment Regulations and Tables_ address **special expenses** (_frais particuliers_) — costs that fall outside ordinary child-rearing expenditures and that are shared proportionally between the parents. Special expenses typically include childcare costs linked to a parent's employment or education, medical and dental costs not covered by insurance, post-secondary education expenses, and costs for extracurricular activities where those costs are significant and reasonable in the circumstances. Each parent contributes to special expenses in the same ratio as their share of combined income. > ⚠️ Special expenses are not automatic — they must be established and either agreed upon or ordered by a court. Keeping organized records of all childcare invoices, medical expenses, and activity fees is essential if you intend to share these costs with the other parent. Without documentation, courts cannot assess what is owed or whether a cost was reasonable. ### Undue Hardship Either parent may apply for a deviation from the guideline amount on the basis of **undue hardship** (_difficultés excessives_). Undue hardship is not a low bar — it requires demonstrating that strict application of the tables would cause genuine and disproportionate hardship that the formula does not account for. Circumstances that may support an undue hardship claim include unusually high access costs (particularly in long-distance parenting arrangements), a legal obligation to support another child or dependent from a prior relationship, or exceptional debt incurred during the relationship for the benefit of the family. For example, a parent ordered to pay guideline support while also supporting an adult child with a severe disability from a prior relationship, and while facing mounting medical debt from a family emergency, might establish undue hardship. A parent cannot invoke undue hardship simply because the guideline amount is higher than they would prefer — the standard requires hardship that is genuinely disproportionate in the circumstances. > 💡 **Did you know?** The income-shares model embedded in the _Child Support Payment Regulations and Tables_ has remained substantively stable for more than two decades — an unusual degree of durability for a regulatory instrument in an area as litigated as family law. Quebec courts have expanded and refined the model through jurisprudence, particularly in high-income cases and shared custody arrangements, but the core formula has not been fundamentally restructured since the model's introduction. That stability reflects broad judicial and governmental confidence in the design's underlying fairness. ### Enforcement of Child Support in Quebec Quebec operates a mandatory automatic enforcement mechanism for [child and spousal support](https://goldwaterdroit.com/en/services/child-spousal-support) through Revenu Québec. Court orders and notarized agreements that are homologated by the court are automatically enrolled in Revenu Québec's source deduction program, which deducts payments directly from the payor's income and remits them to the recipient parent — similar to a payroll deduction. This system was designed to reduce defaults and eliminate the need for recipients to pursue individual enforcement proceedings in most cases. Goldwater Droit has played a significant role in shaping the contours of Quebec's support enforcement system. In _H.(J.) c. F.(W.)_, 2003 CanLII 47187 (QC CA), the firm obtained a landmark Court of Appeal ruling confirming that child and spousal support creditors have the right to enforce their own judgments directly — rather than being required to rely exclusively on Revenu Québec. The Court held that government authorities cannot restrict a creditor's access to justice by withholding financial information or by negotiating directly with debtors without the creditor's knowledge or consent. This decision remains a key precedent ensuring that support recipients retain direct control over collection, and that state agencies act with fairness and accountability in their dealings with both creditors and debtors. The firm extended this enforcement jurisprudence into the context of self-employed professionals in _Droit de la famille — 113647_, 2011 QCCS 6247, establishing that Revenu Québec must automatically garnish professional fees paid to self-employed physicians through the Régie de l'assurance maladie du Québec (RAMQ) where those physicians owe child or spousal support. The court ruled that professional income paid through RAMQ is subject to the same source deduction rules as employment income — closing a long-standing gap that had allowed some self-employed professionals to avoid automatic withholding by routing earnings through professional fees rather than salary. > 💡 **Did you know?** Quebec's automatic enforcement system through Revenu Québec is opt-out rather than opt-in. All court-ordered support is automatically enrolled unless both parties specifically request exemption and satisfy the conditions to do so. This design significantly reduces defaults compared to systems where the recipient parent must initiate enforcement proceedings each time a payment is missed. Even so, the automatic system does not resolve every situation — particularly where a payor's income is irregular, self-generated, or structured to avoid standard withholding. --- ## How the _Child Support Payment Regulations and Tables_ Have Evolved Quebec's income-shares model predates the federal _Child Support Guidelines_ by several years. The original provincial framework was developed in the early 1990s as part of a broad reform of family law and civil procedure, built into the province's Code of Civil Procedure structure from the outset. Before that reform, child support in Quebec was calculated on a largely discretionary basis, without binding tables or formulas. The introduction of the income-shares model represented a fundamental shift toward predictability and consistency — reducing the role of judicial discretion for ordinary cases while preserving it for exceptional ones, such as the high-income and enforcement matters described above. The regulation has been updated periodically to reflect changes in the cost of living and in the economic conditions that the tables are designed to mirror. Significant revisions have adjusted the table values themselves, refined the income determination rules — particularly around self-employment income and income attribution — and clarified the treatment of shared custody arrangements. The 2016 reform of the [_Code of Civil Procedure_](https://canlii.ca/t/8smj), which came into force on January 1, 2016, brought structural changes to family law proceedings in Quebec and reorganized how support applications are processed. The _Child Support Payment Regulations and Tables_ were updated in coordination with those procedural reforms. More recently, the establishment of the _Tribunal unifié de la famille_ (Unified Family Tribunal) has affected how child support applications are heard in Quebec. The TUF was designed to consolidate family law matters — including child support — before specialized judges in the jurisdictions where it operates, rather than routing them through the general dockets of the Superior Court and the Court of Quebec. Its constitutional validity has been challenged by the Procureur général du Québec (Attorney General of Quebec); that challenge is ongoing as of April 2026. This page will be updated as developments occur. --- ## _Child Support Payment Regulations and Tables_ vs. the Federal _Child Support Guidelines_ Quebec's _Child Support Payment Regulations and Tables_ and the federal [_Child Support Guidelines_](https://canlii.ca/t/10pq) are the two principal frameworks governing child support calculations in Canada. In Quebec, the provincial regulation applies. Everywhere else in Canada, the federal guidelines govern. The fundamental distinction is the **income model**. Under the federal _Child Support Guidelines_, only the paying parent's gross income determines the base support amount. The receiving parent's income plays no role in the base calculation — though it can become relevant in claims for special or extraordinary expenses and undue hardship. Under Quebec's _Child Support Payment Regulations and Tables_, both parents' gross incomes are combined, and the basic parental contribution is divided proportionally between them. A recipient parent with significant income will receive less support than a recipient parent with little or no income, because the Quebec model credits the recipient's own financial capacity. This difference has real practical consequences. A recipient parent with a high income receives substantially less child support under the Quebec model than they would under the federal model. Conversely, a payor with a very low income may owe less under the Quebec model if the recipient parent earns significantly more. In some cases — where the recipient parent out-earns the payor — the direction of the net payment can reverse entirely: the formally "receiving" parent may owe child support to the formally "paying" parent. Both models include frameworks for special or extraordinary expenses, and both permit departures in cases of undue hardship. Both models have table ceilings above which judicial discretion takes over. The enforcement mechanisms differ: Quebec's system relies on automatic source deduction through Revenu Québec, while federal enforcement in other provinces operates through provincial garnishment regimes and court-driven collection proceedings. The _Divorce Act_ formally recognizes Quebec's provincial guidelines as the "applicable guidelines" for divorcing spouses in Quebec. This means that the _Child Support Payment Regulations and Tables_ — not the federal tables — govern child support calculations even where the _Divorce Act_ is the legal source of the obligation. The result is that the provincial regulation is the operative instrument for virtually all child support calculations in Quebec, regardless of whether the parents were married. > 💡 **Did you know?** One counterintuitive result of Quebec's income-shares model is that a recipient parent who earns more than the payor may actually end up owing child support to the payor — not receiving it. This surprises many people who are accustomed to thinking of child support as a one-directional obligation, but it reflects the internal logic of the model precisely: both parents bear financial responsibility in proportion to their means, and the net obligation flows in whichever direction the math dictates. --- ## Frequently Asked Questions ### Does Quebec use the same child support tables as other provinces? No. Quebec has its own provincial child support regulation — the _Child Support Payment Regulations and Tables_ — which uses a different formula from the federal tables that apply in other provinces. Quebec's income-shares model considers both parents' incomes to calculate a proportional contribution, while the federal model is based only on the paying parent's income. Even in divorce proceedings, Quebec courts apply the provincial tables rather than the federal ones. ### How is child support calculated in Quebec if both parents earn similar incomes? In Quebec, both parents' gross annual incomes are combined and the tables determine the total basic parental contribution for the number of children involved. Each parent then contributes proportionally. Where parents earn similar incomes, the net payment flowing between them will be relatively small — because each parent is already bearing roughly half the contribution through their own proportional share. The amount is not zero, but the disparity drives the figure. ### Does the other parent's income affect how much child support I receive? Yes — and this is one of the most significant differences between Quebec's system and the federal model used elsewhere. In Quebec, the recipient parent's income is factored into the calculation. A recipient parent with substantial earnings will receive less than they would under the federal guidelines, because the Quebec model credits their own financial capacity. This outcome surprises many people who expect child support to be calculated based only on what the paying parent earns. ### Does child support change in a shared custody arrangement? Yes. Where each parent has the child for at least 40% of the year, the basic calculation is adjusted to reflect the direct expenditures each parent makes while the child is in their care. However, shared custody does not eliminate child support — where there is significant income disparity, the higher-earning parent will still owe the lower-earning parent a net amount. The shared custody adjustment reduces the obligation; it does not erase it. ### Can a court order more than what the tables say? Yes, in two circumstances. First, where combined parental income exceeds the table ceiling, courts exercise discretion and may order an amount based on the children's actual needs and the parents' genuine capacity to contribute. Second, where either parent demonstrates undue hardship — that strict table application causes genuinely disproportionate hardship — the court may adjust the amount upward or downward. Neither route is granted routinely; both require evidence. ### Does child support apply if the parents were never married? Yes. Both parents in Quebec carry a legal obligation to support their children regardless of whether they were married, in a civil union, or in a _de facto_ relationship. The _Child Support Payment Regulations and Tables_ apply equally to all parents. The parents' relationship to each other — and whether they have any support obligations to each other — is a separate question from child support. ### Is child support taxable income in Quebec? No. Under current Canadian tax rules, periodic child support payments are neither deductible for the paying parent nor taxable income for the receiving parent. This applies to child support specifically. Periodic spousal support is treated differently — it is deductible for the payor and taxable for the recipient. Understanding which type of payment you are dealing with is important, and the distinction is not always obvious in practice. ### What happens if a parent stops paying child support in Quebec? Court-ordered child support and homologated support agreements are automatically enrolled in Revenu Québec's source deduction program, which deducts payments directly from the payor's income. Where that mechanism is insufficient — because the payor is self-employed, earns irregular income, or has otherwise structured their finances to avoid withholding — the recipient parent has the right to pursue enforcement directly, including through the courts. As confirmed by the Court of Appeal in _H.(J.) c. F.(W.)_, 2003 CanLII 47187, support creditors in Quebec have the right to enforce their own judgments and are entitled to access financial information necessary to do so. --- ## Speak with a Family Lawyer Quebec's child support model involves intersecting income calculations, discretionary departures for high-income earners and undue hardship cases, and enforcement mechanisms that do not resolve every situation automatically. The calculation method is distinctive in Canada, and its outcomes can differ materially from what a parent might expect under the federal model used in other provinces. Whether you are establishing a support arrangement for the first time, seeking to modify an existing order due to a change in income or custody, or navigating a dispute over income attribution or special expenses, the outcome depends significantly on how both parents' financial circumstances are characterized and presented to the court. The firm's track record in high-income cases and enforcement disputes demonstrates how critical skilled legal representation is at each stage.
