Few parts of a separation cause more anxiety than spousal support. It reaches directly into your monthly budget and can shape your finances for years, and unlike child support, which follows a fixed table, spousal support turns on judgment, argument, and the specific history of your relationship.

The good news is that spousal support is one of the most negotiable and defensible issues in family law. Entitlement, the income figures used, the length of the relationship, whether a party is making reasonable efforts toward self-sufficiency, and how support interacts with property and child support are all live questions that a well-prepared case can shift substantially. At Kazandji Law, our Toronto family lawyers act for both support recipients and payors across Toronto and the Greater Toronto Area. This page explains, in plain language and with sources, exactly how spousal support works in Ontario in 2026, who qualifies, how amount and duration are estimated, how it is taxed, and how it can be changed or ended.

One theme runs through everything below: the Spousal Support Advisory Guidelines are advisory, not law. They are a widely used calculation tool, but they do not decide whether you are owed support in the first place, and they are not binding on a judge.^[4] Understanding the difference between entitlement (a legal question) and quantum (a math question) is the single most important idea on this page.

What is spousal support?

Spousal support is a payment from the higher-income spouse to the lower-income spouse after a relationship ends. It is conceptually separate from child support (which is for the children) and from property division (which divides what the couple built). Spousal support exists to deal with the income consequences of the relationship, for example, where one partner stepped back from a career to raise children or support the other's advancement, or where one spouse is simply left in genuine financial need after a long marriage.

Canada has a no-fault family law system. The reasons a marriage ended, an affair, who "left" whom, do not affect the obligation to pay support. The Divorce Act expressly directs courts not to consider spousal misconduct when making a spousal support order.^[1] Support is about economics, not blame.

Support can be paid two ways: periodic (a set amount each month, the most common form) or as a lump sum (a single payment). It can be time-limited or, in longer relationships, indefinite. It can be agreed in a separation agreement or ordered by a court, and it can later be varied or terminated when circumstances change. Each of these choices carries different legal and tax consequences, which is why the structure of a support deal matters as much as the number.

Two legal regimes: married vs. common-law in Ontario

Which law applies to your case depends on your relationship and what you are asking for. This is a frequent source of confusion, so it is worth getting right.

Married spouses who are divorcing: the federal Divorce Act

If you are married and seeking spousal support as part of a divorce, the federal Divorce Act applies, and its rules are the same across Canada. The support power is in section 15.2, which lets a court order one spouse to pay "such lump sum or periodic sums… as the court thinks reasonable for the support of the other spouse."^[1] Married spouses can also seek support under Ontario's Family Law Act, for instance, when they have separated but are not (or not yet) pursuing a divorce.

Common-law partners: Ontario's Family Law Act

Ontario law extends spousal support to many unmarried couples, but only if they meet a threshold. Under section 29 of the Family Law Act, a "spouse" for support purposes includes two people who are not married to each other and have cohabited (lived together in a conjugal relationship):^[2]

• continuously for at least three years; or
• in a relationship of some permanence, if they are the parents of a child.

Meeting this definition is what makes a common-law partner eligible to ask for support. It does not, by itself, mean support will be ordered, entitlement still has to be established on the merits, exactly as it does for married spouses. If you are unsure whether your relationship qualifies, our lawyers can assess the length and nature of your cohabitation and where the line falls in your circumstances. (Note: Ontario's three-year threshold is provincial; other provinces use different periods, and Quebec does not give de facto spouses a support right at all.)^[3]

The threshold question: are you entitled to spousal support?

Before any dollar figure is calculated, a court (or a negotiation) must resolve entitlement. This is the heart of a spousal support case, and it is where experienced advocacy makes the biggest difference. The Supreme Court of Canada has recognized three legal bases for entitlement, and a case can rest on one or more of them.

1. Compensatory support

This is support to compensate a spouse for the economic advantages and disadvantages that flowed from the relationship, the classic example being a spouse who gave up or scaled back a career to raise children or run the household so the other could work and advance. The leading case is Moge v. Moge, where the Supreme Court of Canada rejected a narrow "sink-or-swim" view of self-sufficiency and held that the economic consequences of the marriage and its roles must be shared fairly.^[5] The Divorce Act captures this idea directly: an order should "recognize any economic advantages or disadvantages to the spouses arising from the marriage or its breakdown" and apportion the financial consequences of child care.^[1]

2. Non-compensatory (needs-based) support

Support can also be based simply on need, even without a clear career sacrifice, where the breakdown of a relationship leaves one spouse unable to meet a reasonable standard of living while the other can afford to help. This basis was recognized in Bracklow v. Bracklow, which confirmed that entitlement can arise from need and dependency created by the relationship, not only from compensable sacrifice.^[6] It reflects the Divorce Act's goal of relieving economic hardship arising from the breakdown.^[1]

3. Contractual support

Entitlement can flow from an agreement, a marriage contract, cohabitation agreement, or separation agreement in which the parties set out (or waive) spousal support. Courts generally respect properly negotiated agreements, but they are not untouchable. In Miglin v. Miglin, the Supreme Court set out a two-stage test for when a spousal support agreement should be followed and when a court may intervene, looking at how the agreement was made and whether it still reflects a fair outcome in the parties' current circumstances.^[7] Full financial disclosure and independent legal advice make an agreement far more likely to hold up.

Critically, a difference in income is not, by itself, an entitlement. The SSAG themselves say so: "a mere disparity of income that would generate an amount under the Advisory Guidelines formulas[] does not automatically lead to entitlement," and there must be a finding on a compensatory, non-compensatory, or contractual basis before the formulas are used.^[4] This is precisely why simply plugging numbers into an online calculator can be misleading.

What courts weigh in deciding entitlement and amount

Both the Divorce Act (s. 15.2(4)) and the Family Law Act (s. 33(9)) direct courts to consider the whole picture, the condition, means, needs, and other circumstances of each spouse. In practice, the factors that matter most include:^[1][2]

• the length of the marriage or cohabitation;
• the roles each person played during the relationship (breadwinner, primary caregiver, both);
• each spouse's income, earning capacity, assets, and financial needs;
• the age and physical and mental health of each spouse;
• the care of the children and its effect on a parent's ability to earn;
• the standard of living the couple enjoyed together; and
• any existing order, agreement, or arrangement about support.

How much and for how long? The Spousal Support Advisory Guidelines (SSAG)

Once entitlement is established, the next question is quantum: how much per month, and for how many years. In Ontario this is estimated using the Spousal Support Advisory Guidelines (SSAG), developed for the Department of Justice. Two points about their status are essential and often misunderstood:

• They are advisory, not law. Unlike the Federal Child Support Guidelines (which are legislated and binding), the SSAG "have not been legislated… They are not legally binding. Their use is completely voluntary", a starting point for negotiation and adjudication, applied within the existing legal framework.^[4]
• They produce a range, not a single number. The formulas generate a range for both amount and duration, leaving room to argue where a particular case should fall.^[4]

The SSAG work by income sharing, they look primarily at the incomes of the parties and the disparity between them. Importantly, "income sharing does not mean equal sharing."^[4] There are two main formulas, and which one applies depends on whether there are dependent children with a concurrent child support obligation.

The "without child support" formula

Where there are no dependent children, this formula applies and leans heavily on the length of the relationship. Under the basic without-child-support formula, as stated in the Guidelines:^[4]

• Amount: 1.5% to 2% of the difference between the spouses' gross incomes for each year of the relationship, up to a maximum range of 37.5% to 50% of the gross income difference for relationships of 25 years or more. (The top end is capped so it does not leave the payor with less than the recipient, the "net income cap.")
• Duration: 0.5 to 1 year of support for each year of the relationship, with support becoming indefinite (duration not specified) after 20 years, or, if the relationship lasted 5 years or longer, when the years of the relationship plus the recipient's age at separation add up to 65 or more (the "rule of 65").

"Indefinite" does not mean "forever." It means no fixed end date is set at the outset; the support can still be reviewed, varied, or terminated later as circumstances change (for example, on retirement or once self-sufficiency is achieved).

The "with child support" formula

Where there are dependent children and child support is being paid, a different and more complex formula applies. Because child support must be calculated first and given priority, and because child and spousal support are taxed differently, this formula works from net incomes rather than gross. It aims to leave the recipient with between 40% and 46% of the couple's combined individual net disposable income (INDI), that is, their net incomes after child support is taken out.^[4] Duration under this formula is more flexible and is tied to both the length of the relationship and the ages of the children.

Ceilings, floors, and why the number is only a starting point

The SSAG set an income ceiling and floor by reference to the payor's gross income: the formulas apply in the ordinary way between a payor gross income of about $20,000 (floor) and $350,000 (ceiling); above the ceiling, support is no longer purely formulaic and the analysis becomes more discretionary.^[4] Real cases also involve determining income accurately (a major issue for the self-employed, business owners, and anyone whose paper income understates their true earning capacity, where a court may impute income), locating a figure within the range, "restructuring" by trading amount against duration, and recognized exceptions that justify departing from the formulas.^[4] This is exactly the terrain where advocacy changes outcomes, and where a firm-specific number should never be published as a promise. We build a defensible income and entitlement position first, then use the SSAG to frame a fair range.

A note of caution: free online "spousal support calculators" only approximate the SSAG, and they cannot decide entitlement, resolve disputed income, or account for exceptions. Treat any calculator result as a rough starting point, not an answer.

How spousal support interacts with child support

When both child and spousal support are in play, the law is clear about the order of priority. The Divorce Act requires a court to give priority to child support: it must determine child support first, and if giving priority to child support means less (or no) money is available for spousal support, the court says so in its reasons.^[1a] Both parents have an obligation to support their children, and that obligation comes first.

This priority is also why the "with child support" SSAG formula uses net incomes after child support is deducted, the child support is carved out before spousal support is estimated. If you are dealing with both at once, the two must be planned together, along with parenting time and decision-making, because the parenting schedule can affect the child support figure, which in turn affects what is available for spousal support.

How spousal support is taxed

Tax treatment depends on how support is paid, and it can change the real value of a deal significantly. The general rules from the Canada Revenue Agency are:^[8]

• Periodic spousal support paid under a court order or written agreement is generally deductible to the payer and must be included as taxable income by the recipient (provided the CRA's conditions are met, including that any child support is fully paid). This is reported on specific lines of the tax return, the payer's deductible amount on line 22000 and the recipient's taxable amount on line 12800.
• Lump-sum spousal support is generally not deductible to the payer and not taxable to the recipient, because a one-time payment is usually not treated as a "support payment" for tax purposes.
• Child support under orders or agreements made after April 1997 is neither deductible nor taxable.

These differences matter enormously when comparing offers. A periodic amount and a lump sum that look equivalent on paper can have very different after-tax values once deductibility is factored in. Structuring support with the tax consequences in mind, and confirming the CRA conditions are satisfied, is a routine but high-value part of what we do. (This page is general information, not tax advice; specific tax questions should be confirmed with an accountant or the CRA.)

How long can you claim spousal support? Timing and limitation issues

Timing is one of the most misunderstood areas of spousal support, so here is the current position for Ontario:

• Married spouses (Divorce Act): There is no fixed statutory limitation period to seek spousal support as corollary relief in a divorce. That said, delay can hurt a claim, a long, unexplained gap after separation can weaken entitlement (particularly a needs-based claim) and complicate the evidence. Seeking advice promptly protects your position.
• Common-law partners (Family Law Act): There is no limitation period to bring a claim for spousal support under the Family Law Act. The Limitations Act, 2002 expressly provides that there is no limitation period for "a proceeding to obtain support under the Family Law Act," and the older two-year limitation that had applied to unmarried partners' support claims (former Family Law Act s. 50) was repealed when that Act came into force.^[11] In practice, however, waiting can still undermine a claim on the merits, and property claims are governed by separate, strict deadlines, so common-law partners should not treat the absence of a firm support deadline as a reason to delay.

Importantly, the no-limitation rule for support is distinct from the deadlines that apply to property (equalization) claims between married spouses: under Family Law Act s. 7(3), an equalization claim must generally be started by the earliest of two years after a divorce, six years after separation, or six months after a spouse's death.^[2] Because the support and property rules interact with divorce steps that do have deadlines, the safest course is to get advice early rather than assume you have unlimited time.

Changing or ending spousal support: variation and termination

A spousal support order or agreement is not necessarily permanent. Support can be varied (increased, reduced, or suspended) or terminated when there has been a material change in circumstances, a change that was not foreseen when the order or agreement was made and that has some continuity to it.

• Under the Divorce Act (s. 17), a court can vary spousal support where there has been a change in the "condition, means, needs or other circumstances" of either former spouse since the order was made.^[9]
• Under Ontario's Family Law Act (s. 37), a court can vary a support order on proof of a material change in the dependant's or payor's circumstances (or where new evidence emerges).^[10]

Common triggers include a substantial and lasting change in either party's income, job loss, serious illness or disability, retirement, or the recipient achieving self-sufficiency (or, in some cases, re-partnering). Not every change qualifies, a temporary dip, or a change that was already anticipated in the agreement, usually will not. Because both variation motions and defences against them turn on careful evidence about what changed and whether it was foreseeable, this is another area where preparation is decisive. If your circumstances have changed, do not simply stop paying or assume support should continue unchanged, apply to vary, or you risk enforcement or arrears.

Enforcing spousal support in Ontario

Once support is set by a court order (or a separation agreement filed with the court), payments in Ontario are typically enforced through the province's Family Responsibility Office (FRO), which collects support from the payor and passes it to the recipient. If payments fall into arrears, the FRO has significant enforcement powers, including garnishing wages and bank accounts, intercepting certain government payments, suspending a driver's licence, and reporting to credit bureaus. If your former partner has stopped paying, or if you are facing enforcement you believe is unfair or based on an outdated order, we can help you enforce, respond, or bring a motion to vary.

Common myths about spousal support in Ontario

"We were never married, so I don't owe (or can't get) spousal support." Not necessarily. Common-law partners who cohabited for at least three years, or who have a child together and were in a relationship of some permanence, can qualify under Ontario's Family Law Act.^[2]

"Whoever caused the breakup pays." False. Canada has no-fault family law, and the Divorce Act tells courts to ignore spousal misconduct when deciding support.^[1]

"The online calculator says $X, so that's what I'll pay or receive." A calculator only estimates the SSAG range and cannot decide entitlement, resolve disputed or imputed income, or apply exceptions. The Guidelines are advisory, and a real result can fall anywhere in (or, with good reason, outside) the range.^[4]

"Indefinite support means I pay forever." "Indefinite" only means no end date is fixed at the start. Support can still be reviewed, varied, or terminated on a material change, for example, on retirement or once the recipient becomes self-sufficient.^[9]

"A lump sum and monthly support worth the same are equivalent." Usually not, once tax is considered: periodic support is typically deductible and taxable, while a lump sum generally is neither.^[8]

"We signed a prenup waiving support, so that's final." Agreements carry real weight, but under Miglin a court can still review a spousal support agreement in some circumstances. Proper disclosure and independent legal advice are what make a waiver robust.^[7]

The spousal support process, step by step

Whether your case resolves by agreement or in court, it generally moves through the same stages. Understanding them helps you see where a strong position is built.

1. Financial disclosure

Everything starts with full, honest financial disclosure from both sides, income, assets, debts, and expenses, usually captured in a sworn Financial Statement. Support cannot be fairly assessed without it, and incomplete or evasive disclosure is one of the most common reasons cases stall. This stage is also where income disputes (especially for the self-employed) begin.

2. Assessing entitlement and the SSAG range

Next, we assess whether there is an entitlement, compensatory, non-compensatory, contractual, or a combination, and, if so, run the SSAG to establish a defensible range for amount and duration based on the correct income figures and the length of the relationship.

3. Negotiation and the separation agreement

Most spousal support is resolved by agreement rather than trial. A negotiated separation agreement can set the amount, duration, tax treatment, and review or termination triggers, and, done properly, with disclosure and independent legal advice, it gives both sides certainty. Many couples reach these terms through negotiation or family mediation.

4. Court application, if needed

If the parties cannot agree, either can apply to court. Interim (temporary) support can be ordered while the case proceeds, and the court can make a final order after considering the statutory factors and the evidence. Contested support cases in the Ontario courts commonly take many months to resolve.

5. Review, variation, or enforcement over time

After an order or agreement is in place, life changes. Support may need to be reviewed or varied on a material change, or enforced through the FRO if payments stop. A good agreement anticipates this by building in clear review points where possible.

How Kazandji Law approaches spousal support

Spousal support rewards preparation and clear thinking. We start by pinning down the two questions that decide everything, is there an entitlement, and what is the right income figure?, because getting those right is worth far more than arguing about the last few dollars of a range. From there, we push for a resolution that is fair, tax-efficient, and durable, whether that means a negotiated separation agreement, mediation, or litigation when a fair deal is not on offer.

We act for both sides of these disputes. For recipients, we work to establish entitlement and secure appropriate, lasting support; for payors, we scrutinize claimed entitlement, challenge inflated income figures, and press for terms and end-points that reflect reality, including reasonable expectations of self-sufficiency. Because spousal support rarely stands alone, we handle it alongside divorce and separation, property division, child support, and parenting arrangements, so the whole settlement fits together.

Frequently asked questions

Is spousal support mandatory in Ontario?

No. Spousal support is never automatic. A person must first establish an entitlement, on a compensatory, needs-based, or contractual basis, and the other spouse must have the ability to pay. A difference in income alone does not create an entitlement.

Do common-law partners get spousal support in Ontario?

They can. Under the Family Law Act, a common-law partner is eligible to claim spousal support if the couple cohabited continuously for at least three years, or were in a relationship of some permanence and are the parents of a child. Eligibility is a threshold; entitlement still has to be established on the merits.

How is the amount of spousal support calculated?

Once entitlement is established, amount and duration are estimated using the Spousal Support Advisory Guidelines, which share income between the spouses. The "without child support" formula uses gross income and the length of the relationship; the "with child support" formula uses net incomes after child support. Both produce a range, and the Guidelines are advisory, not binding.

How long does spousal support last?

It depends on the length of the relationship and the circumstances. Under the without-child-support formula, duration is roughly half a year to a year of support for each year of the relationship, becoming indefinite after 20 years or under the "rule of 65" (years together plus the recipient's age at separation totalling 65 or more). Indefinite means no fixed end date, not necessarily forever.

Is spousal support taxable?

Periodic spousal support paid under a court order or written agreement is generally deductible to the payer and taxable to the recipient, if the CRA's conditions are met. A lump-sum payment is generally neither deductible nor taxable. Child support (post-April 1997) is neither deductible nor taxable.

Does it matter who caused the separation?

No. Canada has no-fault family law, and the Divorce Act directs courts not to consider spousal misconduct when deciding spousal support. Support is based on the economics of the relationship, not on blame.

Can spousal support be changed after it is set?

Yes. Support can be varied or terminated if there is a material change in circumstances that was not foreseen when the order or agreement was made, for example, a lasting change in income, job loss, serious illness, retirement, or the recipient becoming self-sufficient. You generally have to apply to vary rather than simply stopping payments.

What is the difference between spousal support and child support?

Child support is money for the children and follows the Federal Child Support Guidelines (which are binding). Spousal support is for a spouse and addresses the income consequences of the relationship. When both apply, the law gives priority to child support, which is calculated first.

Do we have to go to court to decide spousal support?

No. Most spousal support is resolved by agreement, often through negotiation or mediation, and set out in a separation agreement. Court is available when the parties cannot agree, and a judge can order interim support while the case proceeds.

Can we agree in a prenup or cohabitation agreement to waive spousal support?

You can address or waive support in a domestic contract, and courts give such agreements real weight. However, under the Supreme Court's decision in Miglin, a court can still review a spousal support agreement in some circumstances. Full financial disclosure and independent legal advice for each party make a waiver much more likely to be upheld.

What happens if my ex stops paying spousal support?

Support set by court order (or an agreement filed with the court) can be enforced through Ontario's Family Responsibility Office, which can garnish wages and bank accounts, intercept certain payments, and suspend a driver's licence, among other measures. If payments have stopped, we can help you enforce the order or respond if enforcement against you is based on an outdated order.

How is income determined if my spouse is self-employed or hiding income?

Determining income is one of the most contested parts of a support case. Where a spouse's reported income does not reflect their true earning capacity, common with self-employment, corporations, or deliberate under-employment, a court can impute income. This often requires careful review of financial records and, where needed, expert evidence.

How much does a spousal support lawyer cost?

Fees depend on the complexity of the case and whether it resolves by agreement or proceeds to court. Kazandji Law offers a free initial consultation and will give you a clear picture of the process and likely cost before you decide anything.
