A Practical Guide to Spousal Support in Ontario

When a marriage or common-law relationship ends in Ontario, one of the biggest financial questions is whether one spouse should pay support to the other. It’s referred to as “spousal support” in Ontario and Canada (and “alimony” in the U.S.), and this type of payment is intended to help ensure fairness after a breakup, especially when one spouse was financially dependent on the other.

Let’s break down how spousal support works under Canadian law, how courts calculate it, and what some real-life scenarios might look like.

Factors of Spousal Support in Ontario

1. What Is the Purpose of Spousal Support?

Spousal support is not meant to punish one spouse or reward the other. Instead, it serves several specific legal purposes:

• To compensate a spouse who gave up work opportunities or earning potential to support the family.
• To help a spouse become financially self-sufficient after the relationship ends.
• To address financial hardship resulting from the breakdown of the relationship.

These goals are specifically reflected in both the Divorce Act (for married spouses) and Ontario’s Family Law Act (for common-law couples). Support may be awarded even in shorter relationships, especially if one spouse made sacrifices or is at risk of economic disadvantage after separation.

2. Who’s Entitled to Spousal Support in Ontario?

How does spousal support work in Ontario? Entitlement to spousal support is not automatic. A spouse may be entitled to spousal support because:

• He or she suffered economic disadvantage due to the relationship (e.g., stayed home or sacrificed career),
• He or she has financial need, and the other spouse has the ability to pay, and/or
• The spouses have a pre-existing separation agreement or court order that sets up an entitlement to spousal support.

Courts also consider whether there are children of the marriage, and which spouse they live with, and how primary decision-making and parenting time is allocated.

3. How Long Does Spousal Support Last?

The duration of any spousal support in Ontario depends on the length of the relationship:

• Shorter marriages may lead to support lasting half to one year per year of cohabitation.
• In longer marriages, especially those lasting 20 years or more, support may be ordered on an indefinite basis.

4. The Role of the Spousal Support Advisory Guidelines 

Once entitlement is established, the next step is to determine how much spousal support should be paid and for how long. This is where the Spousal Support Advisory Guidelines (SSAGs) comes in.

The guidelines are developed by the Canadian federal Department of Justice, but they are not mandatory. Instead, they are widely used across Ontario and Canada by Family judges to provide well-accepted ranges for both the amount and duration of spousal support.  For lawyers especially, the figures are used to guide settlements.

The SSAGs outline two formulas:

• Without child support (where you have no dependent children), and
• With child support (where there is a dependent child).

Note that the SSAGs purposely provide “low” and “mid” and “high” ranges – not precise figures.  By giving judges a range to work with, rather than precise figures it allows them to consider:

• Compensatory factors (e.g., such as where one spouse made a career sacrifice, and this should now be factored in),
• Needs-based justification,
• The recipient spouse’s earning ability, and
• Case-specific nuances that Family Courts are entitled to take into account.

Courts can also impute income to a spouse artificially if they’re underemployed or avoiding work.

5. The Two SSAG Formulas

Built into the SSAGs are two separate formulas, for determining a range of spouse support Ontario.  This is because the law recognizes there should usually be different potential support entitlements, depending on whether the spouses did or did not have children.  They are:

The “Without Child” Spousal Support Formula. This applies when there’s no ongoing child support obligation. The SSAGs simply calculate the amount and duration based on income and length of relationship. Among other things, the formula looks at the difference between the spouses’ gross annual incomes, and sets up a range of support accordingly.

The “With Child” Spousal Support Formula. This formula applies when a parent is also paying child support.  It also focuses on the spouses’ relative incomes, but then factors in the child support payments. Once a certain financial threshold is reached, it usually results in support being granted to the lower-income spouse.

6. Settling on a Support Figure

As mentioned, the SSAGs identify a range of appropriate spousal support, not a specific figure.  When making a support order, the Ontario courts are still required to look at all the circumstances of the relationship, and come up with a support arrangement that is fair in the circumstances.

The relevant factors include:

• Length of marriage,
• Age of the youngest child,
• Recipient’s age, and
• Potential crossover to no‑child formula.

The court will also adjust the order in extreme circumstances; for example high income spousal support cases (where the paying spouse earns over $350,000 per year) usually falls outside standard SSAG ranges. On the other end, low income cases (where the payor earns less than $20,000) may see only limited support or no support being ordered.

And an important note:  Even if the spouses have an agreement that covers spousal support, it must still pass certain tests for being reasonable, in line with a Supreme Court of Canada decision called Miglin v. Miglin.

7. Real-Life Examples of Spousal Support

Let’s look at a few simplified examples to show how the SSAGs might apply:

Example 1: 15-Year Marriage, No Children

John earns $120,000 annually; Susan earns $40,000. The income gap is $80,000.

Based on these figures, the SSAG formula suggests that Johns should pay between $18,000 and $24,000 in annual support to Susan each year. At the judge’s option, and based on all the other considerations, this translates to somewhere between $1,500 and $2,000 per month. The duration of John’s support-paying obligation would likely be 7.5 to 15 years.

Example 2: 10-Year Marriage, Two Children

Ayesha earns $100,000; Malik earns $60,000. Ayesha also pays $1,200 per month in child support. After taxes and deductions, their disposable incomes are calculated, and spousal support is set to bring Malik’s share up to around 46% of their combined disposable income.

In this scenario, Ayesha might pay spousal support of about $700–$1,000 per month, in addition to child support. The support duration will be tied to the spouse’s circumstances, but also to the duration of the child support obligation.

8. Support Calculators

SSAGs calculations, especially the “with child” formula, are complex. They typically require specialized software, which is used by most Family lawyers when advising their clients.  For a rough estimate, see MySupportCalculator.ca (which is not formally endorsed by the courts, but are typically used by them as a tool), since it allows for a DIY option.

Final Thoughts

Spousal support in Ontario isn’t “one size fits all.” It depends on entitlement, financial situations, and the broader circumstances of the relationship. While the Spousal Support Advisory Guidelines provide a helpful framework, courts have flexibility to adapt spouse support Ontario orders to fit the facts of each case.
