Yes. Under the Ontario Family Law Act, common-law partners can be entitled to spousal support if they have lived together continuously for at least three years, or if they have a child together and are in a relationship of some permanence. However, entitlement is not automatic and depends on income disparity and financial interdependence.
When a long-term relationship ends, the financial shock can be overwhelming. A widespread myth in Canada is that if you are not legally married, you have absolutely no financial obligations to your ex-partner, nor do they have any to you. In Ontario, this is simply not true. The law recognizes that unmarried couples often build intertwined lives, make career sacrifices for one another, and rely on each other financially. If you are navigating a separation, reaching out to a local family lawyer from our directory can help you understand exactly what you might owe or be owed.
Whether you reside in downtown Toronto, Mississauga, or a smaller community like Sudbury, the provincial rules governing unmarried couples are the same. Unmarried partners do not have the same automatic property division rights as married couples, but when it comes to monthly financial assistance, the rules are remarkably similar. Let us explore the precise steps and requirements for claiming or defending against a spousal support claim as a common-law partner in Ontario.
Step-by-Step Process in Ontario
Establishing a claim for financial assistance after a common-law split requires proving your legal status first, followed by demonstrating a genuine financial need. Here is the general process most applicants follow when dealing with the Superior Court of Justice or negotiating privately.
Step 1: Proving Your Common-Law Status
Before any money changes hands, you must prove that your relationship meets the legal definition of common-law under the Ontario Family Law Act. You must demonstrate that you and your partner cohabited continuously for at least three years. Alternatively, if you share a child (biological or adopted), you only need to show that you were in a “relationship of some permanence,” which can be significantly less than three years. Gathering old lease agreements, joint utility bills, and CRA tax returns where you declared your common-law status is crucial here.
Step 2: Establishing Entitlement
Just because you meet the three-year rule does not mean you automatically get a monthly cheque. You must prove “entitlement.” Generally, Ontario courts look for one of three things: compensatory entitlement (you sacrificed your career to raise children or support your partner’s business), non-compensatory entitlement (you are experiencing severe financial hardship following the breakup while your partner is wealthy), or contractual entitlement (you have a written Cohabitation Agreement guaranteeing support).
Step 3: Completing Financial Disclosure
If entitlement is established, both parties must completely open their books. You will both be required to complete a Form 13 Financial Statement (or Form 13.1 if property is also being debated). This involves swearing an oath and providing full disclosure of your income, expenses, assets, and debts. You will need to attach your last three years of CRA Notices of Assessment and recent pay stubs to give an accurate picture of your current earning capacity.
Step 4: Calculating Quantum and Duration
To determine exactly how much should be paid and for how long, lawyers and judges rely on the Spousal Support Advisory Guidelines (SSAG). These guidelines use complex formulas factoring in both incomes, the length of cohabitation, and whether child support is also being paid. While the SSAG is not legally mandatory, the Superior Court of Justice heavily relies on it to ensure fairness across the province. A local family law firm uses specialized software to run these calculations for you.
Step 5: Negotiating or Filing in Court
Most common-law partners choose to resolve their financial disputes outside of court by drafting a legally binding Separation Agreement. This is far less stressful and much cheaper. However, if your ex-partner refuses to negotiate or hides their income, you may need to file an Application at your local Superior Court of Justice courthouse to have a judge formally order the payments.
How Much Does it Cost in Ontario?
The cost of resolving a common-law spousal support dispute depends entirely on the level of conflict between you and your ex-partner. Here are the typical expenses you can expect in Ontario as of May 2026:
- Lawyer Fees: Most family lawyers in Ontario charge between $250 and $600 CAD per hour. Drafting a standard Separation Agreement usually costs between $2,000 and $5,000 CAD.
- Court Filing Fees: If you must go to court, filing an Application costs approximately $224 CAD. Setting the matter down for a trial adds another $445 CAD in government fees.
- Mediation Services: Hiring a private mediator to help you agree on a monthly amount typically costs between $150 and $400 CAD per hour, usually split equally between both partners.
| Resolution Method | Average Cost (CAD) | Level of Conflict |
|---|---|---|
| Amicable Separation Agreement | $2,000 – $4,000 | Low |
| Lawyer-Assisted Mediation | $5,000 – $10,000 | Medium |
| Litigation in Superior Court | $15,000 – $40,000+ | High |
How Long Does the Process Take?
Resolving financial matters can be swift if both parties are transparent. If you mutually agree to exchange your CRA documents and negotiate via lawyers, a finalized Separation Agreement can be signed in 2 to 4 months. Conversely, if you are forced to file an Application in a busy jurisdiction like Brampton or Toronto, it can easily take 1.5 to 3 years to reach a final trial, though a judge can grant a temporary (interim) support order much sooner.
Frequently Asked Questions (FAQ)
Does paying support mean they get half my house?
No. In Ontario, common-law partners do not have automatic rights to the equalization of net family property. Spousal support is strictly about monthly income assistance, not dividing physical assets like the home or your pension, unless an equitable trust claim is successfully proven.
What if my partner refuses to work after we separate?
The law requires the recipient spouse to make reasonable efforts to become self-sufficient over time. If your ex-partner intentionally remains unemployed, your lawyer can ask the court to “impute” an income to them, meaning the support calculation will be based on what they *should* be earning, not their actual zero income.
Can a Cohabitation Agreement prevent spousal support?
Yes. A properly drafted Cohabitation Agreement (often called a common-law prenuptial agreement) can include a mutual waiver of spousal support. However, for the Superior Court of Justice to uphold it years later, both parties must have received independent legal advice and provided full financial disclosure when signing it.
Is common-law support taxable?
Yes. Under Canada Revenue Agency (CRA) rules, periodic (monthly) spousal support payments are tax-deductible for the payor and are considered taxable income for the recipient, provided there is a written agreement or court order in place.
Does having a child change the three-year rule?
Absolutely. If you and your partner have a child together and are living in a relationship of some permanence, you do not need to wait three years to qualify for common-law status under the Family Law Act. You could potentially claim support even if you only lived together for a year.
