The Short Answer
Generally, no — spousal support in Ontario is not automatically permanent. Duration is generally assessed based on the specific circumstances of the relationship and the parties, and can range from a defined, time-limited period to an indefinite duration, depending on the facts. See our guide to spousal support in Ontario for the broader framework this fits within.
What Generally Affects Duration
Duration is generally influenced by factors like the length of the relationship, the recipient's ability to become self-sufficient, any compensatory basis for support (such as career sacrifices made during the relationship), and the ages and circumstances of both spouses. Longer relationships, and relationships involving significant economic interdependency, are generally associated with longer potential durations, often referenced through the (non-binding) Spousal Support Advisory Guidelines.
"Indefinite" Doesn't Automatically Mean Forever
Where support duration is described as "indefinite" rather than fixed to a specific end date, that generally means no automatic end date has been set — not that support is guaranteed to continue permanently regardless of future circumstances. Indefinite support can generally still be reviewed or changed later if there's a material change in circumstances, such as the recipient becoming self-sufficient.
Can Duration Be Revisited Later?
Generally, yes. Whether support was originally time-limited or indefinite, it can generally be revisited if circumstances change materially — for example, a significant change in either spouse's income, health, or ability to work. See our guide to changing support for how that process generally works.
Frequently Asked Questions
Does "indefinite" spousal support mean it lasts forever?
Not necessarily — it generally means no fixed end date was set initially, but indefinite support can still generally be reviewed or changed if circumstances change materially later.
What relationship length tends to lead to indefinite support?
There's no fixed cutoff, but longer relationships, particularly those involving significant economic interdependency, are generally more likely to be associated with longer or indefinite support, assessed on the specific facts.
Can time-limited spousal support be extended?
Generally, yes, if there's a material change in circumstances that justifies revisiting the original arrangement, though this isn't automatic.
Does spousal support automatically end at retirement?
Not automatically — retirement can be a material change worth revisiting, but it doesn't generally end support on its own without the arrangement being formally addressed.
Is spousal support duration the same as child support duration?
No, they're assessed separately and can follow very different timelines, since they address different financial relationships — one is about the children, and the other is about the spouses.
