Northwest Territories Child Support Laws: Guidelines & Enforcement

In the Northwest Territories, child support is calculated using the Federal Child Support Tables, which set the monthly base amount according to the paying parent's gross annual income and the number of children. The territory's own Child Support Guidelines (Regulation R-138-98, made under the Children's Law Act) mirror the federal guidelines and use the same federal tables. The Divorce Act governs divorcing married parents; the Children's Law Act and Family Law Act govern all others. Special expenses are shared in proportion to each parent's income.

Which Guidelines Apply in the Northwest Territories

The Two-Track System

Canada operates a two-track child support system. Which track applies depends on whether the parents were married and whether either of them is pursuing a divorce.

If parents were married and one of them applies for a divorce under the federal Divorce Act (RSC 1985, c. 3 (2nd Supp.)), the Federal Child Support Guidelines (SOR/97-175) apply automatically. The Northwest Territories is not a designated province or territory, so the federal guidelines govern all Divorce Act proceedings involving Northwest Territories residents, with no local variant to displace them.

If parents were never married, or if married parents separate without commencing divorce proceedings, then territorial or provincial guidelines apply instead of the federal guidelines. In the Northwest Territories, the applicable instrument is Regulation R-138-98 made under the Children's Law Act, S.N.W.T. 1997, c. 14 (the "NWT Child Support Guidelines"). The Family Law Act also provides a basis for support applications. The NWT guidelines are described by Justice Canada as "essentially the same as the federal Guidelines" and use the federal tables for basic amounts.

The practical result is that the table amount a payor owes is virtually identical under either track for Northwest Territories residents, because both tracks use the same federal tables. The main procedural differences relate to disclosure timelines and court procedures, not the dollar amount.

Not a Designated Province or Territory

Three provinces (Manitoba, New Brunswick, and Quebec) are designated under the federal Divorce Act, meaning their own provincial guidelines apply even to divorce proceedings when both parents live there. The Northwest Territories is not designated. Federal guidelines apply in full to all Northwest Territories divorce proceedings, and residents can use the Justice Canada Child Support Table Look-up tool (available at justice.gc.ca) to calculate amounts directly.

Calculating the Basic Table Amount

Step 1: Determine the Payor's Annual Income

Income for child support purposes starts with line 15000 ("Total income") of the payor's most recent CRA T1 General tax return or Notice of Assessment. This gross figure is then adjusted in accordance with Schedule III of the Federal Child Support Guidelines. Adjustments may include adding back employment expenses claimed on the return, grossing down eligible dividends to their actual amount, or adjusting self-employment income where business deductions have reduced taxable income below true available resources.

Because the table amounts already build in the effect of income taxes and territorial tax rates, income is used on a pre-tax (gross) basis. Both parents must exchange three years of tax returns, notices of assessment, and, where applicable, business financial statements or employment letters.

Courts may impute income to a parent whose stated income does not accurately reflect their capacity to earn. Grounds for imputation include voluntary under-employment or unemployment (except where required for child care, health, or education), receipt of dividend or capital-gains income taxed at preferential rates, trust income, and residency in a jurisdiction with significantly lower tax rates. Where annual income fluctuates considerably (common in the resource and construction industries that employ many Northwest Territories residents), a court may average income over several years or adjust for a one-time receipt such as a bonus or severance payment.

Step 2: Apply the Federal Tables for the Northwest Territories

The Federal Child Support Tables (Schedule I to SOR/97-175, updated October 1 2025 to reflect 2023 CRA tax rules) include a separate table for the Northwest Territories. The table sets out a monthly base amount keyed to the payor's gross income (in $1,000 increments) and the number of children. The resulting figure is the legally presumed correct basic amount of support.

The 2025 update replaced the 2017 tables. Parents with annual income at or below $16,000 have a table amount of zero. Existing court orders made before October 1 2025 are not automatically changed by the new tables; a party must apply to court or use the recalculation service to bring an older order into line with current figures. For support calculated retroactively for any period between November 22 2017 and September 30 2025, the 2017 tables apply.

Justice Canada provides a free 2025 Child Support Table Look-up tool at justice.gc.ca where parents can enter the payor's territory of residence (Northwest Territories), income, and number of children to obtain the applicable monthly amount.

The Canada child support calculator offers a similar estimate for a Northwest Territories payor, based on gross annual income and number of children. It gives only the federal base table amount, without section 7 expenses or the shared-parenting adjustment described below.

Step 3: Custody Arrangement Adjustments

The basic table amount assumes the child lives primarily with one parent.

Primary residence (more than 60% of time with one parent). The parent with whom the child lives less than 60% of the time pays the full table amount for the payor's income level and number of children.

Shared parenting time (each parent at least 40%). Section 9 of the Federal Child Support Guidelines applies when each parent exercises not less than 40% of parenting time over the course of a year. In these circumstances, the court must consider: (a) the table amount for each parent based on their respective incomes; (b) the increased costs of shared parenting, because both households must maintain space and necessities for the children; and (c) the conditions, means, needs, and other circumstances of each parent and each child. The set-off of the two table amounts is the usual starting point, but courts have consistently recognised that the set-off alone understates the true cost of shared parenting and may award more than the difference to reflect duplicated household expenses.

Split custody. Section 8 applies where one or more children reside primarily with each parent (meaning different children are split between the households). The support order is the difference between what each parent would pay if the other parent were seeking an order against them. This statutory set-off method is distinct from the section 9 shared-parenting adjustment.

Special or Extraordinary Expenses (Section 7)

The table amount covers basic costs: food, clothing, shelter, and ordinary incidentals. Section 7 of the Federal Child Support Guidelines provides for additional amounts above the table for special or extraordinary expenses. These are shared by the parents in proportion to their respective incomes, after deducting any contribution from the child.

Six categories of section 7 expenses are recognised:

1. Child care expenses arising from the recipient parent's employment, illness, disability, or education and training programme.
2. The portion of medical and dental insurance premiums attributable to the child.
3. Health-related expenses exceeding insurance reimbursement by more than $100 in a year, including orthodontics, physiotherapy, speech therapy, counselling, prescription drugs, hearing aids, and eyeglasses.
4. Extraordinary expenses for primary or secondary schooling or other educational programmes that meet the child's particular needs.
5. Post-secondary education expenses.
6. Extraordinary expenses for extracurricular activities.

An expense qualifies as "extraordinary" if it exceeds what the requesting parent can reasonably cover given their income and the support already received, or if the court considers it extraordinary having regard to the amount of the expense, the nature and number of programmes, the child's special needs or talents, the overall cost of the programmes, and any other relevant factor. Courts must account for subsidies, benefits, tax deductions, and credits available to either parent for the expense, but must exclude the Canada Child Benefit and provincial or territorial equivalents from that calculation.

Disputes over section 7 expenses are common. Best practice is to retain receipts, confirm insurance coverage before incurring the expense, and obtain the other parent's advance agreement in writing where possible.

Duration: Age of Majority and Beyond

The Northwest Territories sets the age of majority at 19. For purposes of the Divorce Act, a "child of the marriage" is a child who, at the material time, is either: (a) under the age of majority and has not withdrawn from the parents' charge; or (b) at or over the age of majority but unable, by reason of illness, disability, or other cause, to withdraw from the parents' charge or obtain the necessaries of life.

The age of majority being 19 in the Northwest Territories means support obligations under territorial orders ordinarily continue until that birthday, unless the child withdraws from the parents' charge earlier by leaving home and supporting themselves independently. It is a common misconception that support ends automatically at 19. The obligation continues whenever the statutory conditions are met.

Canadian courts have consistently held that pursuing full-time, reasonable post-secondary education constitutes an "other cause" within the meaning of paragraph (b) above. A first-year university student at 19 who has not voluntarily left the parents' charge remains a "child of the marriage" for Divorce Act purposes, and a court may order continued support. The amount and conditions of support for adult children in post-secondary education are assessed on a case-by-case basis, taking into account the child's own resources (student loans, part-time earnings, scholarships), the cost of the programme, and both parents' incomes.

For children unable to support themselves due to illness or disability, there is no fixed end date; support may continue indefinitely as long as the statutory test is satisfied.

Varying and Updating Child Support

Annual Income Disclosure

Child support is not a once-and-done calculation. Both parents are required to exchange updated income information each year (typically tax returns and notices of assessment) so that the support amount can be kept current. If the payor's income rises, the support amount should increase to match the new table figure. If income falls, an application can be made to reduce it.

Where parents agree on a new amount reflecting updated income, they can formalise the change through a consent order or an updated separation agreement without a court hearing.

NWT Child Support Recalculation Service

The Northwest Territories offers a free NWT Child Support Recalculation Service administered through the Department of Justice (recalculation@gov.nt.ca). The service recalculates existing child support orders annually on the basis of current income information, without requiring either parent to return to court.

Eligibility conditions: both parents must reside in the Northwest Territories, the order must have been made in the territory or be an agreement enforceable under NWT law, and the children must be minors or dependants. The application requires Form 1 (Application with Instructions) and Form 5 (Income Questionnaire). Annual income information from the payor is the primary input.

Using the recalculation service is substantially less expensive and faster than a court application. Orders that include a recalculation clause are automatically eligible; other orders may need amendment to include such a clause before the service can be used.

Court Variation

Where parents cannot agree and the recalculation service does not apply, either parent can bring a variation application before the Northwest Territories Supreme Court. The applicant must demonstrate a material change in circumstances since the last order: a significant change in income, a custody rearrangement crossing the 40% shared-parenting threshold, or a change in the child's needs. The 2025 update to the federal tables has been recognised in other Canadian jurisdictions as capable of constituting a change of circumstances justifying variation of pre-October 2025 orders.

Undue Hardship

Section 10 of the Federal Child Support Guidelines allows either parent to apply for a different amount on grounds of undue hardship. Recognised hardship circumstances include: unusually high debts reasonably incurred to support the family before separation; unusually high travel costs to exercise parenting time (a significant issue in the Northwest Territories, where communities are remote and air travel between Yellowknife and smaller communities is often the only practical option); a legal obligation to support another person; a legal obligation to pay support for a child from another relationship; and a child in shared custody with exceptional special-needs costs.

Even where undue hardship is established, no variation is made if the applicant's household would have a higher standard of living than the other household after applying the guideline amount.

Enforcement: The Maintenance Enforcement Program

How the MEP Works

The Maintenance Enforcement Program (MEP), operated by the Northwest Territories Department of Justice, is the territory's primary enforcement body for child and spousal support orders. Its office is located at the YK Centre East in Yellowknife (phone: 867-767-9258, toll-free in NWT: 1-800-661-0798, email: mep@gov.nt.ca).

When a support order or enforceable agreement is registered with the MEP, the program takes over collection and disbursement of payments. The MEP monitors compliance, receives payments from the payor, and forwards them to the recipient. Registered parties can track payment status through the MEP's online support payment tracker.

The MEP uses the full range of territorial enforcement tools available to it. These include:

• Wage garnishment directed to the payor's employer.
• Seizure or garnishment of bank accounts and other financial assets.
• Suspension of the payor's Northwest Territories driver's licence.
• Registration of a lien or charge against the payor's real property.
• Reporting arrears to credit bureaus.
• Contempt of court proceedings where the payor has the means to pay but refuses.

The MEP does not obtain court orders, modify existing orders, or provide legal advice or representation. Those functions remain with the court and with lawyers.

Federal Enforcement Under FOAEA

The federal Family Orders and Agreements Enforcement Assistance Act (FOAEA, RSC 1985, c. 4 (2nd Supp.), with key amendments in force November 15 2023) supplements the territorial MEP with three federal tools.

First, a tracing service enables the MEP or a recipient to obtain the residential address and employer of a defaulting payor from federal data banks, even where the payor has left the Northwest Territories.

Second, federal payment interception under the Garnishment, Attachment and Pension Diversion Act (GAPDA) allows interception of federal payments otherwise owed to the payor: income tax refunds, Employment Insurance benefits, Old Age Security, and other federal disbursements.

Third, federal licence denial allows the denial of a Canadian passport and any federal licence when the payor is more than three months in arrears or owes more than $3,000 in unpaid support.

Interjurisdictional Enforcement

If the payor lives in another Canadian province or territory, the MEP has reciprocal enforcement arrangements with all other Canadian maintenance enforcement programs. If the payor lives in a foreign country, reciprocal enforcement is available with numerous international partners through the Interjurisdictional Support Orders Act, S.N.W.T. 2002, c. 19. The MEP assists with registering NWT orders in other jurisdictions and registering foreign orders for enforcement in the Northwest Territories.

Practical Guidance for Northwest Territories Residents

Keep records of all financial disclosures. Both parents are required to provide updated income information annually. Retain tax returns, notices of assessment, and any other financial documents exchanged with the other parent, as well as written confirmation of receipt.

Use the federal table look-up tool. Justice Canada's 2025 Child Support Table Look-up at justice.gc.ca is free, authoritative, and covers the Northwest Territories specifically. Run the calculation before any court appearance or negotiation.

Factor in section 7 expenses from the outset. Child care, uninsured health costs, and post-secondary education add substantially to the table amount in many families. Negotiate a clear process for approving, documenting, and splitting these expenses at the same time as the basic order is made.

Register with the MEP. Self-enforcement of support orders (relying on the other parent to pay voluntarily) leaves recipients without recourse if payments stop. Registering with the MEP transfers enforcement responsibility to the government and provides access to all provincial and federal enforcement tools without the recipient having to return to court.

Apply for recalculation annually. The NWT Child Support Recalculation Service is free and eliminates the cost of a court application simply to bring an existing order in line with updated income. If both parents live in the territory and the order qualifies, there is little reason not to use it.

Understand the implications of remote geography. Many Northwest Territories communities are accessible only by air or winter road. Travel costs for parenting time can be substantial. Where these costs create genuine hardship relative to the table amount, section 10 of the federal guidelines allows a court to consider an undue hardship claim. Document travel expenses carefully.

Seek legal advice for complex situations. The general framework described here covers most situations, but special circumstances (a parent who is self-employed in a northern resource business, a payor employed in a remote camp on a rotation schedule, a child with complex medical needs, or an international enforcement scenario) benefit from advice from a family lawyer practising in the Northwest Territories.

For the framework that applies across all Canadian provinces and territories, see the Canada Child Support Laws hub.

Frequently Asked Questions

Which child support guidelines apply in the Northwest Territories?

The Northwest Territories uses territorial guidelines (Regulation R-138-98 under the Children's Law Act) that are essentially identical to the Federal Child Support Guidelines (SOR/97-175) and use the same federal tables. For divorced married parents, the Federal Child Support Guidelines apply directly under the Divorce Act. For unmarried or separated-but-not-divorcing parents, the territorial guidelines apply. The table amounts are the same under both sets of guidelines for Northwest Territories residents.

What is the age of majority for child support in the Northwest Territories?

The age of majority in the Northwest Territories is 19. Support does not automatically end at 19. It continues for any child who cannot become self-supporting because of illness, disability, or other cause, including pursuit of full-time, reasonable post-secondary education. Many people incorrectly believe support ends at 19; the obligation persists whenever the statutory test is met.

How is the monthly child support amount calculated in the NWT?

The basic monthly amount is set by the Federal Child Support Tables for the Northwest Territories. The calculation uses three inputs: (1) the payor's annual gross income from line 15000 of their CRA tax return, adjusted per Schedule III of the federal guidelines; (2) the number of children requiring support; and (3) the payor's territory of residence (Northwest Territories). Justice Canada's free 2025 Child Support Table Look-up tool at justice.gc.ca produces the applicable monthly figure.

What are section 7 special expenses, and who pays them in the NWT?

Section 7 expenses are costs above the basic table amount: child care costs arising from a parent's employment or education, medical and dental insurance premiums for the child, uninsured health expenses over $100 per year (including orthodontics, physiotherapy, and prescriptions), extraordinary schooling costs, post-secondary education, and extraordinary extracurricular activity costs. These are shared by the parents in proportion to their respective gross incomes, after accounting for any contribution from the child and any available tax credits or subsidies.

How does shared parenting time affect child support in the Northwest Territories?

If each parent exercises at least 40% of parenting time over the course of a year, section 9 of the Federal Child Support Guidelines applies. The court considers the table amount for each parent, the increased costs of maintaining two households, and each family's circumstances. The set-off of the two table amounts is the starting point, but courts may award more than the set-off to reflect the real cost of shared parenting. Shared parenting does not automatically halve support: the analysis is more nuanced.

How does the NWT Maintenance Enforcement Program work?

The Maintenance Enforcement Program (MEP), based in Yellowknife, collects and disburses support payments, monitors compliance, and enforces court orders using wage garnishment, bank seizure, driver's licence suspension, and other tools. Registration is voluntary for the recipient but strongly recommended. The MEP also handles interjurisdictional enforcement for payors who have moved to another province, territory, or country. Contact: mep@gov.nt.ca, 867-767-9258, toll-free 1-800-661-0798.

Can I change a child support order without going to court in the NWT?

Yes, in two ways. First, if both parents agree on a new amount, they can document it in a consent order or updated agreement. Second, the free NWT Child Support Recalculation Service (recalculation@gov.nt.ca) recalculates existing orders annually based on current income without any court appearance, provided both parents live in the territory and the order qualifies. A court application is necessary only when the parents disagree or when the circumstances involve a material change beyond a simple income update.

What federal enforcement tools are available if a payor stops paying?

The federal Family Orders and Agreements Enforcement Assistance Act (FOAEA) supplements the territorial MEP with three tools: (1) tracing: federal databases can locate a payor who has moved; (2) federal payment interception: income tax refunds, Employment Insurance, Old Age Security, and other federal payments can be redirected to satisfy arrears; and (3) federal licence denial: a passport and any federal licence can be refused when the payor is more than three months or $3,000 in arrears.

Does the NWT have any undue hardship exception to the guideline amount?

Yes. Section 10 of the Federal Child Support Guidelines allows either parent to apply for a different amount on grounds of undue hardship. In the Northwest Territories, high travel costs between remote communities to exercise parenting time are a recognised hardship factor. Other grounds include unusual pre-separation family debts, obligations to support other dependants, or a child with exceptional special needs. Even if hardship is established, no reduction is made if the applicant's household would still have a higher standard of living than the other household.

How do the 2025 federal table updates affect existing NWT support orders?

The October 1 2025 federal table update does not automatically change any existing court order made before that date. A party must apply to court or use the NWT Child Support Recalculation Service to bring an older order into line with the new tables. For retroactive support for any period between November 22 2017 and September 30 2025, the 2017 tables apply. The 2025 update has been treated in other Canadian jurisdictions as a potential change in circumstances justifying a variation application.
