You’re paying spousal support and wondering when it will finally end. Or maybe you’re receiving it and need to know how long you can count on it.
How long spousal support lasts in Ontario depends on your specific marriage and circumstances—there’s no one-size-fits-all answer.
Let me break down the actual factors that determine duration so you can plan your financial future.
No Fixed Duration Rules
Ontario doesn’t have automatic end dates for spousal support. The Spousal Support Advisory Guidelines suggest ranges, but they’re not mandatory law.
Courts have discretion to order support for whatever duration fits your situation.
Short marriages typically mean shorter support. Long marriages often result in indefinite support. But lots of factors beyond marriage length affect duration.
Spousal Support Advisory Guidelines
These federal guidelines provide formula ranges for amount and duration. They’re advisory only—judges aren’t bound to follow them exactly.
For marriages without children, the support duration ranges from 0.5 to 1 year per year of marriage. A 10-year marriage might mean 5-10 years of support, typically.
For marriages with children, the duration ranges from the length of the marriage to the youngest child’s graduation from high school, whichever is longer.
Judges’ Discretion
Courts consider way more than formulas. Your specific circumstances matter more than mathematical calculations.
Judges look at age, health, earning capacity, roles during marriage, and countless other factors. Two identical-looking marriages might result in entirely different support durations.
Marriage Length Impact
How long you have been married is the most significant factor affecting the duration of support. Generally speaking:
Short marriages (under 5 years) often result in limited-term support. Maybe 2-3 years to help the lower earner transition to independence.
Medium marriages (5-15 years) typically mean time-limited support for several years. The exact duration depends on factors beyond just the length of the marriage.
Long marriages (20+ years) often result in indefinite support, especially when one spouse sacrifices a career for family. Indefinite doesn’t necessarily mean forever, but it doesn’t have a set end date.
Understanding spousal support calculations helps, even though that resource covers Alberta—the principles are similar.
The “Rule of 65”
When the combined age and marriage years equal 65 or more, support often becomes indefinite. A couple married for 20 years, where the recipient is 45, meets this threshold. This rule isn’t absolute but guides judicial thinking.
The logic? Someone in their mid-40s or older who sacrificed a career during a long marriage can’t easily rebuild earning capacity. Indefinite support acknowledges this reality.
Compensatory vs. Needs-Based Support
Why you’re getting support affects how long it lasts. Two main categories exist with different duration implications.
Compensatory Support
This compensates for economic advantages/disadvantages from marriage or its breakdown. Maybe you stayed home raising kids while your spouse advanced their career. You sacrificed your earning capacity for the benefit of your family.
Compensatory support often lasts longer because it addresses permanent career damage. You can’t easily get back 15 years of lost career advancement.
Needs-Based Support
This addresses the inability to meet basic needs after separation. Maybe you need support while retraining or re-entering the workforce. It’s transitional—helping you become self-sufficient.
Needs-based support typically has a shorter duration because it’s meant to bridge a gap rather than provide permanent income. Once you’re self-supporting, it ends.
Understanding financial aspects of divorce helps you grasp these distinctions.
Time-Limited vs. Indefinite Support
Court orders specify whether support is time-limited or indefinite. This makes a massive difference for planning your future.
Time-Limited Support
Orders with specific end dates or duration ranges. “Spousal support of $2,000 monthly for 5 years.” Everyone knows when obligations end.
These orders might include review dates before termination. Courts can extend duration if circumstances have changed, but there’s a presumptive end.
Time-limited support is appropriate for shorter marriages or situations in which the recipient can reasonably achieve independence within a defined timeframe.
Indefinite Support
No specified end date. Support continues until circumstances change and warrant modification or termination. Indefinite doesn’t mean permanent or unchangeable, though.
Either party can apply to vary or terminate indefinite support when circumstances change significantly. Retirement, remarriage, or achievement of self-sufficiency might end it.
Indefinite support is common in long marriages, especially when the recipient is older or has limited earning capacity.

Events That End Support
Certain events automatically or typically end spousal support obligations. These create natural termination points regardless of court orders.
Death of Either Party
Support obligations generally end upon the death of either spouse. You can’t typically collect support from a deceased person’s estate.
However, separation agreements sometimes require life insurance to secure support. If you die, insurance proceeds may provide a lump-sum replacement.
Remarriage of the Recipient
When the support recipient remarries, obligations usually end. Their new spouse assumes responsibility for financial support.
Some agreements continue to support despite remarriage, but this is unusual. Courts typically terminate support upon remarriage.
Understanding cohabitation effects helps you know when new relationships impact support.
Common-Law Cohabitation
Living common-law with a new partner might end or reduce support. Courts examine whether the new relationship provides financial support.
Not every new relationship ends in support. Courts look at whether cohabitation is stable, long-term, and provides a genuine financial partnership.
Material Change in Circumstances
Significant changes in income, health, or needs can result in termination of support. The recipient getting a high-paying job might end their need for support.
Similarly, the payor losing their job or becoming disabled might end their ability to pay. Courts modify or terminate based on changed realities.
Self-Sufficiency and Independence
Support aims to help recipients become self-sufficient. Once you achieve independence, support typically ends or reduces.
What does Self-Sufficiency mean?
Courts don’t expect you to maintain the marital standard of living on your own. Self-sufficiency means meeting reasonable needs independently.
If you can cover basic living expenses through employment, you’re probably self-sufficient. You don’t need to match your ex’s lifestyle to end support obligations.
Reasonable Efforts Required
Recipients must make reasonable efforts toward self-sufficiency. You can’t just refuse to work and collect support forever.
Courts expect you to pursue education, training, or employment appropriate to your age, health, and circumstances. Refusing available opportunities might end support.
Age and Health Limitations
Older recipients or those with health issues face realistic limits on self-sufficiency. A 58-year-old who has been out of the workforce for 25 years can’t easily achieve high earnings.
Courts consider these limitations when determining whether true self-sufficiency is achievable. Sometimes it’s not, justifying continued support.
Review and Variation
Support orders often include review dates. These aren’t automatic terminations but opportunities to reassess circumstances.
Scheduled Review Dates
Orders might say “reviewable after 5 years.” This means either party can apply to modify or terminate at that point. The review examines whether circumstances have changed to warrant modification.
Reviews don’t automatically end support. They provide an opportunity to revisit whether current arrangements still make sense.
Material Change Applications
Either party can apply at any time to vary support due to a material change in circumstances. You don’t wait for scheduled reviews if situations change dramatically.
Job loss, serious illness, retirement, or the recipient’s increased earnings may justify variations in applications.
Understanding how to create lasting agreements helps you build in appropriate review mechanisms.
Retirement and Support
Does your support obligation continue after you retire? This depends on your circumstances and the original basis for support.
Retirement as Material Change
Retirement at the normal retirement age typically justifies reducing or terminating support. Your reduced income affects your ability to pay.
However, voluntary early retirement might not end support if you could still work. Courts distinguish between legitimate retirement and income avoidance.
Recipient’s Retirement
When the support recipient reaches retirement age, support might continue if they have inadequate retirement income. Long marriages often continue to receive support through both parties’ retirements.
Courts balance both parties’ retirement needs. The payor shouldn’t fund the recipient’s comfortable retirement while living in poverty themselves.
Modifying Duration
Support duration isn’t set in stone. Circumstances change, and courts can modify time-limited or indefinite support.
Extending Time-Limited Support
If your support was supposed to end after 5 years but you’re still not self-sufficient due to unexpected circumstances, courts might extend it. Health issues, economic downturns, or other legitimate factors justify extensions.
However, you need to show you made reasonable efforts toward independence. Courts don’t reward lack of effort with extended support.
Converting Indefinite to Time-Limited
Indefinite support can become time-limited if circumstances change. Maybe the recipient has completed their education and should now be employable within a specific timeframe.
Courts can impose end dates on previously indefinite support when self-sufficiency becomes reasonably achievable.

FAQs
Is there a maximum duration for spousal support in Ontario?
No maximum exists. Long marriages often result in indefinite support. Duration depends on the length of the marriage, roles, ages, and countless other factors.
Does spousal support automatically end after a certain number of years?
No, unless your court order specifies an end date. Indefinite support continues until circumstances change and warrant termination.
How long for a 10-year marriage?
Advisory guidelines typically suggest 5-10 years. Actual duration depends on ages, incomes, roles during marriage, and whether children were involved.
Can spousal support last longer than the marriage?
Yes, especially for shorter marriages where one spouse made career sacrifices. A 5-year marriage might result in 7-8 years of support.
Does support end when I retire?
Possibly. Retirement at the normal age typically justifies reduction or termination. Early voluntary retirement might not end support obligations.
What happens if my ex remarries?
Their remarriage usually ends your support obligation. Their new spouse becomes their primary financial support source.
Can indefinite support ever end?
Yes. Indefinite means no set end date, not permanent. Material changes in circumstances can terminate indefinite support.
Does my ex have to look for work?
Yes, recipients must make reasonable efforts toward self-sufficiency. Refusing available employment might end support obligations.
How long would it take if there were children involved?
Often longer than childless marriages. Duration ranges from the length of the marriage to when the youngest child finishes high school, whichever is longer.
Can the support duration be extended?
Yes, time-limited support can be extended if legitimate circumstances prevent self-sufficiency despite reasonable efforts.
What if my income drops significantly?
File for variation. A significant income reduction might result in reduced or terminated support. Courts consider your current ability to pay.
Does a common-law relationship end support?
Possibly. Stable, long-term cohabitation providing financial support typically ends obligations. Courts examine each relationship individually.
