Under Ontario’s Family Law Act, both spouses have an equal right to possess the matrimonial home, regardless of whose name is on the title. Therefore, you cannot legally rent out the basement or create a new tenancy agreement without the explicit, written consent of your separating spouse.
Separation almost always brings a wave of financial instability. 💵 When a single household’s income is suddenly split to support two different lives, many people in Ontario look for creative ways to cover the mortgage. If you have an empty basement suite in your Toronto, Brampton, or Ottawa home, renting it out to a tenant might seem like the perfect solution to generate extra cash.
However, family law strictly protects the shared living space of married couples. The matrimonial home holds a special, highly protected status in the province. You cannot treat it like an ordinary investment property. Unilaterally moving a tenant into the basement without your ex’s permission can lead to severe legal penalties. This guide explains the rules surrounding renting out a matrimonial home during a divorce as of June 2026.
Step-by-Step Process for Renting the Home During a Separation
If both spouses agree that rental income is necessary to avoid foreclosure, you can proceed, but it must be done carefully. 📝 Here is how a family lawyer will structure this arrangement to protect both parties.
Step 1: Acknowledge the Equal Right to Possession
The first legal hurdle is understanding Part II of the Family Law Act. Even if you bought the house before marriage, and only your name is on the deed, your spouse has an equal legal right to live in every part of that home. You cannot lock them out, and you cannot lease out a section of their legal residence to a stranger without their consent.
Step 2: Obtain Written Consent from Your Spouse
Before posting an ad online, you must secure your ex-spouse’s agreement in writing. 📧 This is usually handled through a temporary separation agreement or a formal consent order drafted by your lawyers. The document should outline exactly which part of the house will be rented, who will manage the tenant, and how the rental income will be utilized.
Step 3: Draft a Legal Ontario Standard Lease
If consent is granted, you must follow the rules of the Residential Tenancies Act (RTA). You must use the mandatory Ontario Standard Lease form. Keep in mind that once a tenant moves in, they gain massive legal protections. You are suddenly a landlord, and you must maintain the unit, provide heat, and respect the tenant’s privacy, which can be stressful during a bitter divorce.
Step 4: Manage the Rental Income in Trust
The rent money collected from the basement tenant does not belong solely to the spouse who manages the property. 💰 Usually, the temporary separation agreement will mandate that the rental income be used exclusively to pay the joint mortgage, property taxes, and home insurance. Any leftover profit is typically split 50/50, or held in a lawyer’s trust account until the final equalization is completed.
Step 5: Prepare for the Realities of Selling
Eventually, most separated couples sell the matrimonial home. 🏡 Having a tenant in the basement makes selling the property significantly harder. Buyers often want vacant possession. Under Ontario law, you must provide the tenant with at least 60 days’ notice (using an N12 form) and one month’s rent as compensation if the buyer intends to move in themselves.
How Much Does it Cost in Ontario?
Becoming a landlord during a divorce introduces several new expenses that both spouses will have to share. 💵 Consider these costs:
- Legal Fees: Having a lawyer draft the consent agreement to rent the basement typically costs between $800 CAD and $1,500 CAD.
- Insurance Upgrades: Standard home insurance does not cover rental units. Upgrading to a landlord policy will increase your premiums by $300 to $600 CAD annually.
- Tenant Compensation: If you eventually sell the home and the buyer wants the basement empty, you must legally pay the tenant one month’s rent as compensation to leave under an N12 eviction.
- Income Tax: The rental income must be declared to the Canada Revenue Agency (CRA), which could affect your personal tax brackets.
How Long Does the Process Take?
Finding a tenant can happen in a matter of weeks, but the legal entanglement lasts much longer. ⏱ A standard Ontario residential lease commits you to a minimum 1-year term. If your divorce finalizes in 6 months and you are ordered to sell the house, you cannot simply kick the tenant out before their one-year lease expires. This can heavily delay the final payout of your home equity.
| Property Title Status | Can I Rent the Basement Alone? | Legal Consequence of Doing So |
|---|---|---|
| Only My Name is on the Deed | No (if it is the Matrimonial Home). | Spouse can apply for a court order to void the lease and evict the tenant. |
| Both Names are on the Deed | No. | Financial penalties; judge may order you to pay all rent to your spouse. |
| It is an Investment Property (Not where we lived) | Generally Yes (if solely owned). | Income must still be accounted for during the final net family property equalization. |
Frequently Asked Questions (FAQ)
What if my ex-spouse moved out months ago? Can I rent it then?
No. Just because your spouse physically moved out of the home does not mean they abandoned their legal right to possession under the Family Law Act. Until a final separation agreement or court order changes the status of the home, you still need their explicit permission to rent out the space.
What happens if I already rented it out without asking?
Your ex-spouse can file an urgent motion in family court. A judge can legally void the tenancy agreement because you did not have the authority to sign it alone. Furthermore, the judge may penalize you financially for hiding the rental income, reducing your share of the final property division.
Does the rental income affect spousal support?
Yes. Any rental income generated from the basement increases the household income pool. When calculating spousal support and child support under the federal guidelines, this extra cash flow will be factored into the income of whoever is legally receiving the rent money.
What if we are a common-law couple?
The rules are drastically different for common-law couples in Ontario. Common-law partners do not have the special “matrimonial home” protections. If your name is the only one on the deed, you can generally rent out the basement without their permission, though you should always consult a local lawyer to prevent constructive trust claims.
Can a judge force my ex to agree to a tenant?
It is very rare for an Ontario family judge to force a spouse to accept a stranger living in the basement. If the mortgage cannot be paid without a tenant, the judge will typically order that the matrimonial home be immediately listed for sale on the open market instead.
