Spousal Support in Ontario: Eligibility, Duration, and Modification

Written by Russell Alexander ria@russellalexander.com / (905) 655-6335

Who is eligible for spousal support in Ontario?

Eligibility applies to legally married and common-law spouses. The court considers length of relationship, roles, financial impact, and existing agreements.

How long does spousal support last?

Support may be indefinite (for long marriages) or fixed-term. The Spousal Support Advisory Guidelines (SSAG) help courts estimate appropriate duration.

What is a material change in circumstances?

A significant, unforeseen shift—like income loss or illness—that may justify modifying a support agreement or order.

Can prenuptial or separation agreements determine support?

Yes. Courts respect agreements if they meet fairness standards and both parties disclosed finances honestly. Learn more about marriage contracts.

How is spousal support modified?

The court reviews evidence of changed circumstances. Either party can request changes through legal process or mediation.

What are legal limitations on modifying support?

Non-modification clauses in agreements may limit changes, but courts can override if unjust or hardship results.
