Key takeaways
  • Married spouses can claim support, and unmarried partners can too if they lived together for at least three years, or had a relationship of some permanence and a child together.
  • A claim in a Form 8 application needs a financial statement (Form 13 or 13.1) and a Certificate of Financial Disclosure (Form 13A).
  • The other person must be served by someone else aged 18 or older, and the usual deadline to answer is 30 days if they receive it in Canada or the US.
  • A separation agreement can set support without going to court, but it must be understood, based on honest disclosure and not signed under pressure.

You have recently separated and money is uncertain. Maybe one of you earned much more, or one of you stepped back from work to raise children. You want to know what applying for spousal support actually involves, and in what order.

This article walks through who can claim, the choice between agreeing and going to court, the filing steps and forms, and how support is usually collected. Every situation is different, so use it as a map and confirm your own details with a lawyer.

Who can claim spousal support in Ontario

Which law applies depends on your relationship. The federal Divorce Act sets the support rules for married couples who divorce. Provinces set the rules for unmarried partners and for married couples who separate without divorcing, and in Ontario that is the Family Law Act.

In Ontario, married spouses can claim. Unmarried partners can claim if they lived together as a couple for at least three years, or if they were in a relationship of some permanence of any length and had a child together.

Being eligible to ask is not the same as being entitled to receive. A claimant generally needs to show at least one of these: a role in the relationship that prevented building their own career, a need for support after separation while the other spouse can pay, or a legal agreement that provides for support on separation.

Agreement first, or court first?

You do not always need a court to start. A separation agreement can set support without going to court. A court may set it aside, though, if it was not understood, was not based on complete and honest financial disclosure, or was signed under pressure.

Many people try to negotiate first and file only if that stalls. Either way, you will need a clear picture of both incomes, which is why gathering financial records early helps. Ontario.ca lists a large income difference, whether there are children and who cares for them, ages, roles in the relationship, health and ability to support oneself as factors affecting the amount.

The filing steps

If you go to court, you start with a Form 8 application. Here is the general order of steps.

Notice that you cannot serve the papers yourself. Ask a friend, relative or process server who meets the requirements, and keep the details of when and how it was done so the affidavit is accurate.

Deadlines, fees and where to file

The respondent has 30 calendar days to file an Answer if they receive the application in Canada or the US, and 60 calendar days if they receive it elsewhere.

There is no fee to file at the Ontario Court of Justice. The Superior Court of Justice and its Family Court branch may charge fees, and fee waivers are available. Which court is right for you can depend on what else you are claiming, such as a divorce or property, so confirm this before filing.

As one local example, the Newmarket Courthouse for York Region is at 50 Eagle St. W., Newmarket, Ontario L3Y 6B1, and the Superior Court of Justice lists family scheduling there at 905-853-4823. Contact details can change, so confirm them before you rely on them.

After you have an order or agreement: collection

Court-ordered spousal support is automatically filed with the Family Responsibility Office (FRO), which collects from the payor and pays the recipient. A separation agreement must first be filed with the court on Form 26B and then registered with FRO with a registration package.

FRO does not pay you when a payment is missed. A recipient completes a Statement of Arrears to collect unpaid support and interest. FRO has a range of enforcement tools, including garnishing bank accounts and deducting from federal tax refunds.

Tax matters too. Spousal support is generally deductible by the payer and taxable to the recipient for orders or agreements made after April 1997 if the order or agreement clearly states the amount and all child support for the current and previous years is fully paid. An accountant can confirm how this applies to you.

What to do next

Frequently asked questions

Can I claim spousal support if we were never married?

Possibly. Unmarried partners in Ontario can claim if they lived together as a couple for at least three years, or were in a relationship of some permanence of any length and had a child together. You still have to show a basis for support, such as a role that hurt your career or a genuine need.

Do I have to go to court to get spousal support?

No. A separation agreement can set support without going to court, as long as it is understood, based on complete and honest financial disclosure, and not signed under pressure. If you cannot agree, a court application is the usual route.

Can I serve the application on my ex myself?

No. Service must be done through someone else aged 18 or older using special service, and then Form 6B proves it was done.

How much will I get?

It depends on your facts, so it is worth confirming with a lawyer. Ontario.ca lists factors such as a large income difference, children and who cares for them, ages, roles in the relationship, health and ability to support oneself. The Spousal Support Advisory Guidelines are not law, but judges often base decisions on them.
