Spousal support (commonly called alimony) and child support serve fundamentally different purposes in Nunavut family law. Child support provides financial assistance for children's basic needs and is calculated using the Federal Child Support Guidelines, while spousal support compensates for economic disadvantages arising from the marriage breakdown. Under Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 15.3, Nunavut courts must give priority to child support over spousal support when both are at issue, meaning spousal support may be reduced or denied if child support obligations are substantial.

What Is Child Support in Nunavut?
Child support in Nunavut is a mandatory financial obligation paid by one parent to another for the direct benefit of dependent children following separation or divorce. The Federal Child Support Guidelines, SOR/97-175, establish the exact monthly amount based on the paying parent's gross annual income and the number of children. Nunavut adopted these federal guidelines with minor amendments under the Children's Law Act on April 1, 2000. For 2026, no child support is payable for incomes below $12,000, and the updated Federal Child Support Tables that came into effect on October 1, 2025 apply to all new and modified orders in the territory.
The Federal Child Support Guidelines create predictable, formula-driven support amounts that leave little room for judicial discretion at standard income levels. A parent earning $50,000 annually in Nunavut pays approximately $461 per month for one child, $737 for two children, and $965 for three children according to the 2025/2026 tables. These amounts represent the base table amount only—additional "Section 7" expenses for childcare, healthcare, extracurricular activities, and post-secondary education are shared proportionally between parents based on their respective incomes.
How Child Support Is Calculated in Nunavut
Nunavut courts calculate child support using a three-step process mandated by federal law. First, the court determines the paying parent's "line 150" gross annual income from their most recent tax return or Notice of Assessment. Second, the court consults the Federal Child Support Tables for Nunavut to find the base monthly amount corresponding to that income level and the number of children. Third, the court allocates Section 7 special or extraordinary expenses proportionally between both parents based on their respective incomes.
The Nunavut table amounts reflect the territory's unique tax structure and higher cost of living compared to southern provinces. For a parent earning $60,000 annually with two children, the 2026 table amount is approximately $878 per month. Parents earning above $150,000 annually enter a discretionary zone under Section 4 of the Federal Child Support Guidelines, where courts may set support amounts based on the table amount for $150,000 plus a percentage of income above that threshold.
What Is Spousal Support (Alimony) in Nunavut?
Spousal support in Nunavut is a financial payment from one former spouse to another intended to address economic disadvantages arising from the marriage or its breakdown. Under Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 15.2, Nunavut courts must consider four statutory objectives when ordering spousal support: recognizing economic advantages or disadvantages from the marriage, apportioning financial consequences of child-rearing, relieving economic hardship from marriage breakdown, and promoting the recipient's economic self-sufficiency within a reasonable time.
Unlike child support, spousal support in Canada is not governed by mandatory guidelines. The Spousal Support Advisory Guidelines (SSAG), developed by Professors Carol Rogerson and Rollie Thompson with Justice Canada funding, provide advisory formulas that courts frequently reference but are not legally bound to follow. Nunavut courts have adopted the SSAG as a starting point for analysis in most cases, though judicial discretion remains significant.
The SSAG "Without Child Support" Formula
When divorcing spouses have no dependent children, Nunavut courts apply the SSAG "without child support" formula. This formula calculates spousal support as 1.5% to 2.0% of the gross income difference between spouses for each year of marriage or cohabitation. The range caps at 37.5% to 50% of the income difference for marriages lasting 25 years or longer. Duration ranges from 0.5 to 1.0 years of support for each year of marriage, becoming indefinite after 20 years or when the "Rule of 65" applies (marriage duration plus recipient's age at separation equals 65 or more).
For example, consider a 15-year Nunavut marriage where the higher-earning spouse earns $100,000 and the lower-earning spouse earns $40,000. The income gap is $60,000. Applying the formula: 15 years × 1.5% = 22.5% to 15 years × 2.0% = 30% of $60,000, yielding a range of $13,500 to $18,000 annually, or $1,125 to $1,500 per month. Duration would range from 7.5 to 15 years.
The SSAG "With Child Support" Formula
When dependent children exist, the SSAG "with child support" formula uses a more complex calculation based on Individual Net Disposable Income (INDI) rather than gross income percentages. The formula first calculates each parent's INDI by subtracting child support obligations, taxes, and deductions from gross income, then adding government benefits and credits. The formula then targets allocating 40% to 46% of the combined INDI to the recipient spouse.
This approach recognizes that child support already transfers significant income between households and prevents double-counting. Under Divorce Act s. 15.3, if giving priority to child support prevents a spousal support order or reduces its amount, that child support reduction later constitutes a "change of circumstances" justifying a spousal support variation application.
Key Differences Between Alimony and Child Support in Nunavut
The difference between alimony and child support in Nunavut centers on beneficiary, calculation method, legal priority, duration, and tax treatment. Child support benefits children directly while spousal support compensates a former spouse for marriage-related economic disadvantage. Understanding these distinctions helps Nunavut residents anticipate their financial obligations and entitlements during divorce proceedings.
Legal Priority: Child Support Comes First
Nunavut courts must prioritize child support over spousal support under Divorce Act s. 15.3. When a paying spouse's income cannot adequately fund both obligations, the court must first ensure children receive full table-amount child support before allocating any funds to spousal support. The court must record its reasons when spousal support is reduced or denied due to this prioritization. This statutory priority reflects Canadian family law's fundamental principle that children's needs supersede adult financial interests.
Calculation Method: Mandatory vs. Advisory Guidelines
Child support calculation in Nunavut follows the Federal Child Support Guidelines—a mandatory legal framework leaving minimal judicial discretion at standard income levels. Spousal support calculation follows the Spousal Support Advisory Guidelines—an advisory framework that courts frequently reference but may depart from based on individual circumstances. This distinction means child support amounts are highly predictable while spousal support involves more negotiation and judicial judgment.
Duration: Age-Based vs. Marriage-Length Based
Child support in Nunavut typically continues until the child reaches age 19 (the age of majority in the territory) or longer if the child remains in full-time post-secondary education or is unable to become self-supporting due to disability. Spousal support duration depends on marriage length, with the general rule providing 0.5 to 1.0 years of support for each year of marriage. Marriages lasting 20+ years or triggering the Rule of 65 (marriage years plus recipient's age at separation ≥ 65) result in indefinite spousal support subject to review.
Tax Treatment: Deductible vs. Non-Deductible
Spousal support payments made under a court order or written agreement are tax-deductible for the paying spouse and taxable income for the receiving spouse under Canada's Income Tax Act. Child support payments receive the opposite treatment—they are neither tax-deductible for the payor nor taxable income for the recipient. This tax asymmetry significantly affects the net cost and benefit of each support type and often influences negotiation strategies in Nunavut divorce settlements.
Which Is More: Alimony or Child Support?
There is no universal answer to whether alimony or child support produces larger payment amounts in Nunavut—the calculation depends entirely on individual circumstances including incomes, number of children, marriage duration, and each spouse's financial situation. However, several general patterns emerge from the governing formulas.
For shorter marriages with multiple children, child support typically exceeds spousal support. A parent earning $80,000 with three children pays approximately $1,350 per month in base child support under the 2026 Nunavut tables. Even with a substantial income disparity, a five-year marriage would generate SSAG spousal support of only 7.5% to 10% of the income gap—potentially several hundred dollars monthly.
For longer marriages without children, spousal support may equal or exceed what child support would have been. A 25-year marriage with a $100,000 income gap generates SSAG spousal support of 37.5% to 50% of that gap, or $37,500 to $50,000 annually ($3,125 to $4,167 monthly). This amount significantly exceeds the child support that would apply for even three children at comparable income levels.
Enforcement in Nunavut: The Family Support Program
Nunavut's Family Support Program, operated by the Department of Justice in Iqaluit, enforces both child support and spousal support orders. Either parent can register with the Family Support Office (FSO) for automatic payment collection and distribution. The FSO can collect support directly from the payor's paycheque or social assistance deposits, intercept income tax refunds, and take other enforcement measures against non-paying obligors.
Falling behind on child or spousal support in Nunavut triggers serious enforcement consequences. Under federal and territorial enforcement legislation, arrears can result in wage garnishment of up to 25% of gross income, bank account seizure, income tax refund interception at 100%, and federal benefits garnishment. Arrears exceeding $3,000 can result in passport denial and federal licence suspension. The Family Support Office is located at the Allavik Building, 4th Floor, 1106 Ikaluktuutiak Drive, Iqaluit, and can be reached at (867) 975-6100 or toll-free at 1-866-286-0546.
Filing for Support in Nunavut: Court Process and Costs
Nunavut residents seeking child support or spousal support file applications with the Nunavut Court of Justice, which has exclusive jurisdiction over divorce and family law matters in the territory. The court's unified structure makes it unique in Canada—unlike other jurisdictions with separate superior and provincial courts, Nunavut operates a single-level trial court for all matters.
Residency Requirements
Under Divorce Act s. 3(1), at least one spouse must have been ordinarily resident in Nunavut for at least one year immediately before filing a divorce petition. If neither spouse meets this requirement, the divorce must be filed in the province or territory where either spouse qualifies. Support applications connected to a divorce proceeding follow this same jurisdictional rule.
Filing Fees and Court Costs
Nunavut court filing fees are governed by the Court Fees Regulations under territorial legislation. While specific fee amounts should be verified directly with the Nunavut Court Registry at (867) 975-6100 or toll-free at 1-866-286-0546, divorce application fees in Canadian territories typically range from $200 to $300. As of May 2026, verify current fees with the Nunavut Court of Justice Registry before filing.
Required Documents
Divorce applications in Nunavut require completed forms available from the Nunavut Courts website (nunavutcourts.ca). Essential documents include the Application for Divorce (Form 1), Affidavit (Form 7), Financial Statement, and proposed parenting plan addressing parenting arrangements, decision-making responsibility, and parenting time. Support-specific applications require detailed financial disclosure from both parties.
Modifying Support Orders in Nunavut
Both child support and spousal support orders can be varied when a material change of circumstances occurs. Under Divorce Act s. 17, the court must be satisfied that conditions, means, needs, or other circumstances of either party or a child have changed since the original order before making a variation. Common grounds for variation include job loss, significant income changes, remarriage, relocation, or changes in the children's needs.
For child support, the October 1, 2025 update to the Federal Child Support Tables automatically applies to new and varied orders. Existing orders based on earlier tables may be varied to reflect current table amounts if either parent's income has changed. For spousal support, the threshold for variation is higher—courts require evidence of a substantial and unforeseen change that would have produced a different original order if known at the time.
Parenting Arrangements and Support Interaction
The 2021 amendments to Canada's Divorce Act replaced the terms "custody" and "access" with "decision-making responsibility" and "parenting time." In Nunavut, parenting arrangements directly affect child support calculations when parenting time is shared relatively equally between parents.
Under Section 9 of the Federal Child Support Guidelines, when a child spends at least 40% of their time with each parent, the court may set child support using the "set-off" approach—calculating each parent's table obligation and requiring the higher-earning parent to pay the difference. This shared parenting time threshold of 40% (approximately 146 nights annually) can significantly reduce the basic child support amount compared to a primary residence arrangement.
