Spousal Support in Ontario

What is this right?
Spousal support is not automatic — the person asking for it must first establish entitlement. There are three main bases: compensatory (you gave up career opportunities for the family), needs-based (you are at a financial disadvantage after the separation), or contractual (there is an existing agreement).
The Spousal Support Advisory Guidelines (SSAG) provide suggested ranges for amount and duration. While the SSAG are not law, courts rely on them heavily. The without-children formula is 1.5% to 2% of the gross income difference per year of marriage. Duration ranges from half to one year of support per year of marriage.
After 20 years of marriage — or when the "rule of 65" applies (age plus years of marriage equals 65) — support may be indefinite. Periodic spousal support payments are taxable income for the recipient and tax-deductible for the payer.
When does it apply?
Spousal support may apply to:
- Married spouses under the Divorce Act.
- Common-law partners under provincial legislation — most provinces require 2 to 3 years of cohabitation.
- Cases where there is a significant income gap between the partners.
What to Do If Your Spouse in Canada Won't Pay Spousal Support
- Determine entitlement — identify whether your claim is compensatory, needs-based, or contractual.
- Exchange full financial disclosure — income, assets, debts, and expenses.
- Calculate the SSAG range to understand what a court might order.
- Negotiate or mediate before going to court — it is faster and less expensive.
- Consider the tax implications — periodic payments are taxable to the recipient and deductible for the payer.
What should you NOT do?
- Don't assume you're not entitled just because you work — a significant income gap can still justify support.
- Don't delay claiming — waiting too long can weaken your case.
- Don't quit your job — the court can impute income based on what you are capable of earning.
- Don't ignore a support order — enforcement can include wage garnishment and even imprisonment.
- Don't assume a prenuptial agreement is final — courts can set aside agreements that are unfair or were signed under pressure.
How Ontario differs from federal law
Spousal support in Ontario is available to both married and common-law partners. Ontario has broader rights for common-law partners than some other provinces.
- Under Ontario's Family Law Act, a person can claim spousal support if they are married, or if they have lived with their partner continuously for at least 3 years, or if they are in a relationship of some permanence and have a child together.
- Courts consider several factors: the length of the relationship, the roles each person played during the relationship, the effect of the relationship on each person's earning capacity, and each person's financial needs and means.
- The Spousal Support Advisory Guidelines (SSAG) — while not legislation — are widely used by Ontario courts and lawyers to calculate the amount and duration of support based on formulas that account for income, length of marriage, and children.
- Spousal support can be time-limited or indefinite depending on the circumstances. Longer relationships generally lead to longer or indefinite support.
- Like child support, spousal support orders are enforced by the Family Responsibility Office (FRO).
Additional Steps in Ontario
Try to negotiate spousal support through mediation or collaborative family law. You can use the SSAG calculations (available through a family lawyer or online calculators) to estimate a range. If agreement is not possible, apply to court. Legal Aid Ontario provides certificates for eligible applicants. The FRO (1-888-815-2757) enforces spousal support orders automatically.
