How Does A New Spouse Affect An Existing Support Plan?
Remarriage does not automatically change existing support obligations. A person who pays child support or spousal support must continue to follow the terms of the current arrangement unless a court changes the order or the parties sign a new enforceable agreement.
Support obligations in Ontario may arise under the Divorce Act, the Family Law Act, a written Separation Agreement, or a court order. Many support orders are also filed with Ontario’s Family Responsibility Office (FRO), which enforces payments and ensures that the support terms are followed.
Child Support Usually Does Not Change When The Payor Remarries
Child support remains one of the most stable legal obligations after separation. Under Canadian law, child support exists for the benefit of the child rather than the former spouse. For that reason, a parent’s remarriage does not remove or reduce the obligation to support their child.
Courts calculate child support primarily using the Federal Child Support Guidelines, which rely on the income of the paying parent and the parenting arrangement between the parties.
Situations Where Child Support Could Change After Remarriage:
Financial or parenting changes connected to remarriage may become relevant if they amount to a material change in circumstances.
Examples may include:
- Significant increase or decrease in the payor’s income
Change in parenting time or decision making arrangements - Changes in special or extraordinary expenses under section 7 of the Federal Child Support Guidelines
- Claim of undue hardship under the Guidelines
- New legal financial responsibilities that substantially affect the payor’s financial situation

Spousal Support Does Not Automatically End When The Payor Remarries
Ontario courts consider the original purpose of the support arrangement when they assess whether support should continue. Spousal support may arise for several reasons, including compensatory support for sacrifices made during the marriage, non-compensatory support based on financial need, or contractual support created through a separation agreement.
When A Payor’s New Marriage May Affect Spousal Support:
The paying spouse must demonstrate a material change in circumstances that makes the current support arrangement inappropriate.
Situations that courts may consider include:
- Major change in the payor’s income
- New legal obligations to support additional children
- Substantial shift in the payor’s financial capacity
- Evidence that the original support arrangement no longer reflects current financial realities
- Financial changes that significantly affect the payor’s ability to continue the existing support payments
Does Remarriage of the Recipient Affect Spousal Support?
Remarriage alone does not automatically terminate support. Courts still consider the factors listed in the Divorce Act and the Family Law Act, including the economic disadvantages created during the marriage, the length of the relationship, and the recipient’s ongoing financial circumstances.
In many cases, spousal support continues after remarriage if the original order serves a compensatory purpose, such as addressing career sacrifices made during the marriage.
To change the existing arrangement, the paying spouse must usually show a material change in circumstances and bring a Motion to Change under section 17 of the Divorce Act or section 37 of the Family Law Act. The final decision is made by the court.
