Spousal support in Ontario is not automatic after separation or divorce. The first question is whether a spouse has a legal basis for support. If so, the amount and duration depend on the parties' circumstances, including their incomes, relationship history, roles, needs and any child support obligations.
A large difference in income can be important, but it does not by itself establish entitlement. Nor does a number from an online calculator decide what a court would order. This guide explains the questions in a useful order without predicting an outcome for a particular family.
Key takeaways
- Entitlement comes first. The Spousal Support Advisory Guidelines address possible amount and duration after entitlement is established; they do not create entitlement.
- Married and unmarried partners may qualify under different legal routes. Ontario's Family Law Act includes certain unmarried partners for support purposes; the federal Divorce Act applies to married spouses divorcing.
- A range is not a promise. Income evidence, child support, the length of cohabitation, caregiving and agreements can all affect an assessment.
What is spousal support?
Spousal support is money that one spouse may pay the other after separation or divorce. It may address economic disadvantage from the relationship or its breakdown, hardship arising from separation, or financial consequences of caring for children beyond child support. Support may be periodic or, in some cases, a lump sum. The legal basis and proposed terms need to be considered together.
Three separate questions
1. Entitlement: Is there a legal basis for one spouse to receive support?
2. Amount: If so, what payment or range is appropriate in the circumstances?
3. Duration: For what period, or subject to what review or event, should support continue?
Answering one question does not automatically answer the others.
Who can ask for spousal support in Ontario?
For married spouses who are divorcing, the federal Divorce Act provides a route to request spousal support. Ontario's Family Law Act can apply to married spouses who are separating without a divorce proceeding and to unmarried partners who meet its definition of “spouse” for support purposes.
For an unmarried couple, that definition generally includes partners who cohabited continuously for at least three years, or who cohabited in a relationship of some permanence and are parents of a child as described in the Act. Meeting a relationship threshold permits a support claim to be assessed; it does not guarantee a payment. The facts of cohabitation, parentage and the applicable proceeding matter.
Spousal support and division of property are different legal questions. A person should not assume that rules about property division for married spouses also apply in the same way to an unmarried relationship.
What affects entitlement?
Under the Divorce Act, a court considers each spouse's condition, means, needs and circumstances, including the length of cohabitation, the roles each performed and existing support arrangements. The objectives include recognizing economic advantages or disadvantages arising from the marriage or its breakdown, addressing financial consequences of child care beyond child support, relieving hardship, and promoting self-sufficiency where practicable. Ontario's Family Law Act has its own support framework for claims under that Act.
For example, a spouse who stepped away from work to care for children may raise a different entitlement question from a couple who maintained independent careers and similar earning capacity. Financial need, a relationship-related loss of earning opportunity, and an agreement about support may all need attention. The existence of an income gap alone is not a substitute for that analysis.
How is the amount assessed?
Once entitlement is identified, lawyers and courts commonly use the Spousal Support Advisory Guidelines (SSAG) to help assess possible ranges of amount and duration. The SSAG are advisory, not legislation. They use different approaches depending on whether child support is involved, and their ranges need to be considered alongside the governing law and the particular facts.
Accurate income information is central. Employment income, self-employment, bonuses, commissions, business interests and changes after separation may require different analysis. The amount can also be affected by child support, the spouses' roles and means, a prior order or agreement, and the basis for entitlement. A generic calculator may omit disputed income, tax effects or other important circumstances.
What if child support is also payable?
Child support and spousal support are distinct obligations. Under the Divorce Act, child support has priority when the court considers both. The presence of child support can affect the spousal support analysis and the relevant SSAG approach. It does not automatically rule out spousal support. See our guide to child support in Ontario for the separate child support questions.
How long can spousal support last?
There is no single duration for every Ontario relationship. The length of cohabitation, each spouse's age and circumstances, caregiving responsibilities, economic disadvantage, need and ability to become self-supporting may matter. An order or agreement might specify a period, a review, an event, or no fixed end date.
“Indefinite” means that no end date is stated; it does not necessarily mean support can never change. Conversely, a change such as retirement, a new relationship or a child becoming independent does not automatically end every support obligation. The wording of the order or agreement and the legal basis for a change need review before payments are altered.
What if there is already an agreement or order?
A separation agreement, marriage contract or court order can be central to the assessment. Do not assume a waiver, payment term or review clause is effective or ineffective without examining its wording, the circumstances in which it was made and the applicable law. The SSAG do not themselves override an existing agreement.
If finances or family circumstances change, a support term may need review. For example, a significant change in income may raise a question about variation, but it does not automatically replace the amount in an order or agreement. A person paying under an existing obligation should not simply stop or reduce payments based on an informal calculation. Seek advice about the correct route to change it.
Which spousal support question do you need help with?
- Before an agreement: Assess the possible entitlement, financial disclosure and proposed support terms before signing.
- During separation or divorce: Address support alongside child support, parenting or property issues without conflating them.
- After an order or agreement: Review a material change, a stated review date, arrears or an uncertain ending provision.
- Where income is complex: Identify the records needed for a business owner, self-employed spouse or changing compensation.
What to have ready for a consultation
If available, note the dates of cohabitation and separation, whether you are married, whether there are children and an existing child support arrangement, each person's general income sources, any current order or agreement, and the specific support concern. Identify any upcoming court date, signing date or other deadline. A brief description is enough for the initial inquiry; wait for conflict-check and intake instructions before sending detailed confidential financial records.

Frequently asked questions
Is spousal support automatic after divorce?
No. The person requesting support must establish a legal basis. Entitlement, amount and duration require separate consideration; a divorce or income difference alone does not fix the outcome.
Can an unmarried partner request spousal support?
Potentially. Ontario's Family Law Act includes certain unmarried partners who meet the cohabitation or relationship-and-child criteria. Meeting the definition is the starting point, not an automatic entitlement to payment.
Can an online spousal support calculator tell me what I will pay or receive?
It may generate an estimate using its inputs. It cannot establish entitlement or resolve disputed income, an existing agreement, child support interactions or the appropriate result in a particular case.
Does a spouse have to work or become self-supporting?
Economic self-sufficiency is an objective where practicable, but what is reasonable depends on the facts, including the relationship history, caregiving, health, skills and opportunities. It is not a fixed deadline imposed on every recipient.
Does support end if the recipient starts a new relationship?
Not automatically in every case. The terms of the order or agreement and the effect of the changed circumstances need review before anyone changes payments.
Is spousal support taxable or deductible?
The tax treatment depends on the terms and form of the payment and whether Canada Revenue Agency requirements are met. Periodic support under a qualifying written agreement or court order can be treated differently from a lump sum. Get legal and tax advice before relying on a particular treatment.
