What Is Spousal Support in Ontario?

The Basics: Why Spousal Support Exists

Spousal support—sometimes called “alimony”—isn’t just about dollars and cents. In Ontario, family law recognizes that one spouse may need financial help after a marriage or common-law relationship ends. The goal? To address economic disadvantages caused by the relationship or its breakdown.

Types of Spousal Support

  • Compensatory: To address lost career opportunities or contributions to the family.
  • Non-Compensatory (Needs-Based): To help a spouse who is struggling financially post-separation.
  • Contractual: Based on what you and your ex agreed to in a separation agreement.

How Amounts Are Calculated

Ontario courts rely on the Spousal Support Advisory Guidelines (SSAGs). They consider:

  • Length of the relationship
  • Ages of both spouses
  • Roles during the marriage
  • Each person’s income and earning potential

The Big Question: Does Re-Partnering End Spousal Support?

Not Always a Simple Yes or No

People often wonder: “If I move in with someone new, will my spousal support stop?” The short answer: maybe—but not automatically.

The Myth of the “Automatic Termination”

Ontario law doesn’t have a magic switch that turns off spousal support the moment you re-partner. Instead, it depends on the circumstances and the wording of your support order or agreement.

What the Law Says

  • Remarriage or cohabitation can be a “material change in circumstances.”
  • This change can justify reducing, suspending, or even ending support.
  • But you have to bring it to court (or negotiate) for changes to take effect.

 

 

 

 

How Ontario Courts Decide: Key Factors in Changing Support

Material Change in Circumstances

To modify spousal support, you need to show a “material change in circumstances.” Re-partnering qualifies—but only if it substantially affects the recipient’s financial situation.

What the Judge Will Ask

Ontario courts look at:

  • Is the recipient now financially supported by their new partner?
  • Has the recipient’s need for support decreased?
  • Was the original support compensatory, non-compensatory, or contractual?
  • What did you agree to in your divorce or separation agreement?

Evidence Matters

Courts don’t just take your word for it. You’ll need to provide evidence—think proof of cohabitation, shared expenses, or remarriage certificates.

 

 

 

 

Cohabitation: Living Together Without Tying the Knot

Cohabitation means you live with a new partner as a couple, but you’re not legally married. In Ontario, the law treats cohabitation seriously when it comes to spousal support.

  • Shared finances and benefits can reduce the need for support.
  • But it doesn’t always mean support ends—especially if the new relationship isn’t financially supportive.

Remarriage: Saying ‘I Do’ Again

Remarriage can have a bigger impact. Courts often see remarriage as a sign the recipient’s financial circumstances have changed significantly.

  • Some support agreements or orders state that remarriage ends support.
  • If not, you may still need to apply to court to change the order.

Key Differences in Legal Impact

  • Cohabitation: May reduce or end support, depending on the financial interdependence.
  • Remarriage: Often leads to termination, especially for non-compensatory support.

 

 

 

 

Common Scenarios: How Re-Partnering Affects Your Case

Scenario 1: The Recipient Moves In With a New Partner

If you’re receiving spousal support and you start cohabiting, your financial needs may decrease. Your ex could apply to reduce or end support. But if your new partner isn’t helping with expenses, support may continue.

Scenario 2: The Recipient Remarries

Remarriage is a strong argument for changing or ending support, especially if your new spouse supports you financially. But if your support order is compensatory, courts may allow it to continue.

Scenario 3: The Payor Re-Partners

If you’re paying support and you re-partner, the law doesn’t automatically reduce your obligation. Your new partner’s income isn’t considered unless your financial situation drastically changes (e.g., new children to support).

Key Takeaways

  • Each case is unique.
  • The financial arrangements of the new relationship matter.
  • The original reasons for support are crucial.

What About Child Custody and Support After Re-Partnering?

Child Custody: Focus Remains on the Child

Re-partnering usually doesn’t affect child custody arrangements. Ontario family law keeps the child’s best interests front and centre, regardless of your new love life.

Child Support: Separate from Spousal Support

Child support is a separate legal obligation. Even if spousal support ends after re-partnering, child support generally continues unchanged unless there’s a major change in income or custody.

Blended Families: Adding Complexity

If your new partner has children, or you have children together, courts look at all sources of support and the needs of every child. But one parent’s new relationship doesn’t erase their financial responsibility to their own kids.

 

 

 

 

Step 1: Identify a Material Change

First, figure out if your new relationship is a “material change in circumstances.” If you’re sharing finances, living together, or remarried, you may qualify.

Step 2: Try Negotiating

Before heading to court, see if you can reach a new agreement with your ex. Mediation or negotiation can save time, money, and emotional energy.

Step 3: File a Motion to Change

If negotiation fails, you’ll need to file a Motion to Change with the Ontario family court. You must provide evidence of your new circumstances.

Step 4: Court Decision

The judge reviews all evidence and may:

  • Reduce spousal support
  • Suspend it temporarily
  • Terminate it completely
  • Leave it unchanged

Step 5: Update Family Responsibility Office (FRO)

If your support is enforced by the FRO, make sure you update them after any court order changes.

 

 

 

 

Mistakes to Avoid When You Find New Love

Not Disclosing Your New Relationship

Trying to keep your new relationship a secret from your ex or the court? Bad idea. Courts take a dim view of dishonesty, and failing to disclose can backfire.

Assuming Support Ends Automatically

Don’t assume your obligation or entitlement stops the moment you re-partner. Legal agreements and court orders must be followed until officially changed.

Not Getting Legal Advice

Ontario family law is complex. Failing to get professional legal advice can cost you financially—and emotionally.

Bonus Tips

  • Review your original separation agreement before making changes.
  • Keep records of your new living and financial arrangements.
  • Consult an experienced family lawyer early in the process.

Often, yes—especially if your new spouse supports you. But compensatory support may continue in some cases.

 

What if I start paying for my new partner’s kids?

Your own support obligations may not change, but the court can consider your new financial responsibilities if you apply to vary support.

 

Can I negotiate support changes without going to court?

Yes! Many people resolve changes through negotiation or mediation. Court is the last resort.
