Can I Change the Locks During Divorce in Ontario? 2026 Legal Guide

No, you cannot legally change the locks on your matrimonial home during a divorce in Ontario without your spouse's written consent or a court order for exclusive possession. Under Ontario Family Law Act, R.S.O. 1990, c. F.3, s. 19(1), both spouses have an equal right to possession of the matrimonial home regardless of whose name appears on the title. Changing the locks unilaterally violates your spouse's statutory possession rights and could expose you to civil liability, a court order requiring you to restore access, or even criminal charges for mischief under Criminal Code, R.S.C. 1985, c. C-46, s. 430. The only legal paths to changing locks are obtaining an exclusive possession order under Section 24 of the Family Law Act, finalizing a written separation agreement that grants you sole possession, or completing the property transfer following your divorce.

Key Facts: Changing Locks During Divorce in Ontario

Understanding Matrimonial Home Possession Rights in Ontario

Ontario law grants both spouses an absolute equal right to possession of the matrimonial home under Section 19(1) of the Family Law Act, regardless of which spouse holds legal title to the property. This equal possession right means neither spouse can unilaterally exclude the other from the home through actions such as changing locks, installing security systems that deny access, or physically barring entry. The right exists from the date of marriage and continues until the spouses are no longer married or until a court order or signed separation agreement terminates one spouse's possession rights. Even if you are the sole owner of the property and purchased it before marriage, your spouse maintains equal possession rights to the matrimonial home throughout the marriage and separation period.

The matrimonial home receives special protection under Ontario law that distinguishes it from all other marital property. Under Section 21 of the Family Law Act, no spouse may sell, mortgage, lease, or otherwise dispose of an interest in a matrimonial home without the other spouse's written consent. This protection applies even when only one spouse holds title to the property. The enhanced protections exist because the legislature recognized the matrimonial home's unique importance as the family's primary residence and the center of family life. Courts interpret these provisions broadly to ensure both spouses maintain access to stable housing during the often turbulent separation and divorce process.

Attempting to lock out your spouse by changing locks during divorce in Ontario violates these statutory protections and can result in serious consequences. Courts have ordered spouses who changed locks to provide new keys within 24 hours, pay the other spouse's legal costs for bringing an emergency motion, and in extreme cases, face findings of contempt of court. The locked-out spouse can call police and request assistance gaining entry to the home based on their equal possession rights. While police may view this as a civil matter in some circumstances, they generally recognize the locked-out spouse's legal right to access and can require the lock-changing spouse to provide keys or permit entry.

When Can You Legally Change the Locks in Ontario?

You can legally change the locks on your matrimonial home in Ontario only when one of three conditions is satisfied: you obtain a court order for exclusive possession under Section 24 of the Family Law Act, you and your spouse sign a written separation agreement granting you sole possession, or ownership of the property has been legally transferred to you alone following property division. Each pathway has specific requirements and procedures that must be followed precisely to avoid legal liability. Changing locks before satisfying one of these conditions exposes you to court orders requiring restoration of access, cost awards against you, and potential criminal charges.

A separation agreement that addresses possession of the matrimonial home must meet Ontario's legal requirements to be enforceable. The agreement must be in writing, signed by both parties, and witnessed by a neutral third party. Both spouses must provide full financial disclosure of their assets and liabilities before signing. Each party should receive independent legal advice, though this is not strictly required for enforceability. The agreement must be entered voluntarily without duress or coercion. Once a valid separation agreement grants you exclusive possession, you may change the locks and your spouse no longer has a legal right to enter the property.

Property transfer following divorce permanently terminates your former spouse's possession rights to the home. If the divorce judgment or separation agreement awards the matrimonial home to you, the title must be legally transferred through a deed registered on title. Once you hold sole title and the transfer is complete, you become the exclusive owner with full rights to change locks, modify security systems, and deny entry to your former spouse. Until the legal transfer is complete and registered, however, your spouse retains possession rights even if the divorce is finalized and the home was awarded to you.

How to Obtain an Exclusive Possession Order in Ontario

An exclusive possession order under Section 24 of the Family Law Act grants one spouse the legal right to occupy the matrimonial home while requiring the other spouse to vacate, regardless of ownership. Only married spouses can apply for exclusive possession under the FLA; common-law partners must seek alternative remedies. The application must be filed with the Ontario Superior Court of Justice, as the Ontario Court of Justice lacks jurisdiction to make exclusive possession orders. The standard filing fee for an application is $224 as of May 2026, with an additional $280 fee for motions and $280 for case conferences. Fee waivers are available for individuals receiving Ontario Works, ODSP, or meeting specific low-income thresholds.

Courts grant exclusive possession orders reluctantly because they constitute a severe remedy that forces one spouse from their home. Section 24(3) of the Family Law Act establishes six factors courts must consider: the best interests of any children affected, any existing family property or support orders, the financial position of both spouses, any written agreement between the parties, the availability of other suitable and affordable accommodation, and any violence committed by a spouse against the other spouse or children. Courts have consistently held that exclusive possession orders require extraordinary circumstances such as domestic violence, an intolerable living situation, or significant hardship to one spouse or the children.

The best interests of children carry the greatest weight in exclusive possession applications. Section 24(4) of the Family Law Act specifies that courts must consider the possible disruptive effects of a move on the children and the children's views and preferences where ascertainable. Courts generally award exclusive possession to the spouse with primary parenting time to minimize disruption to the children's routines, schooling, and social connections. Ontario case law establishes that children should not be exposed to the adult conflict, unpleasantness, and negativity that occurs when separated spouses continue living under the same roof. Where parental conflict is harming the children's wellbeing, courts are more likely to grant exclusive possession to remove the source of conflict.

Emergency Exclusive Possession Orders for Domestic Violence

Ontario courts can grant emergency exclusive possession orders on the same day the application is filed when domestic violence or immediate safety concerns exist. In urgent situations, the court may hold an emergency hearing within hours of filing, and the applicant may not need to appear in person if the judge determines the evidence establishes immediate risk. Emergency orders typically remain in effect for 14 to 30 days pending a full court hearing where both parties can present evidence. If granted an emergency exclusive possession order, you can change the locks immediately and your spouse must vacate the home.

The application for an emergency exclusive possession order requires detailed evidence establishing the safety threat. Courts consider evidence of physical violence or threats of violence, patterns of controlling or coercive behavior, previous police involvement or criminal charges, threats to children in the home, and any history of violating court orders. Applicants should gather documentation including police reports, medical records of injuries, photographs of damage, text messages or emails containing threats, and affidavits from witnesses. The stronger the evidence of domestic violence, the more likely the court will grant emergency relief.

Once granted, an emergency exclusive possession order is enforceable like a restraining order. Under Section 24(6) of the Family Law Act, police have the authority to arrest without warrant any person they believe on reasonable grounds has contravened an exclusive possession order. Your spouse can be charged with a criminal offense for entering the home in violation of the order, potentially facing fines and imprisonment. After obtaining an emergency order, you should immediately change the locks, document the existing state of the home, and keep a copy of the court order accessible at all times to show police if your spouse attempts to enter.

What to Do If Your Spouse Changes the Locks on You

If your spouse changes the locks and denies you entry to the matrimonial home, call the police non-emergency line and request assistance. Bring proof that you are married and that the property is your matrimonial home, such as your marriage certificate, a piece of mail addressed to you at the property, or identification showing the address. Police can require your spouse to provide you with keys or permit entry based on your equal possession rights under the Family Law Act. While police sometimes characterize lockouts as civil matters and decline to intervene, they generally recognize the locked-out spouse's statutory right to access the matrimonial home.

If police do not assist or your spouse refuses to comply, you must pursue legal remedies through the courts. File an urgent motion in the Ontario Superior Court of Justice seeking an order requiring your spouse to provide you with keys and restore your possession rights. You may also seek an order requiring your spouse to pay your legal costs for bringing the motion. Courts take lockouts seriously as violations of statutory possession rights and typically order restoration of access within 24 to 48 hours. Document the date and time your spouse changed the locks, any communications in which your spouse refused entry, and your efforts to resolve the situation before turning to the court.

Consider whether the lockout situation warrants seeking your own exclusive possession order. If your spouse's behavior demonstrates a pattern of controlling conduct, domestic violence, or creating an intolerable living situation, the lockout may strengthen your application for exclusive possession. Courts may view unauthorized lock changes as evidence of bad faith that weighs in favor of granting the locked-out spouse exclusive possession. Consult a family lawyer promptly to assess your options, as delays can complicate your legal position and may be interpreted as acquiescence to the new living arrangement.

Criminal and Civil Consequences of Changing Locks Illegally

Changing locks on the matrimonial home without legal authority can expose you to criminal charges under the Criminal Code of Canada. The offense of mischief under Section 430 includes willfully obstructing, interrupting, or interfering with the lawful use, enjoyment, or operation of property by any person. Denying your spouse their statutory right to possession of the matrimonial home through a lock change meets this definition. While police often treat spousal lockouts as civil matters, persistent denial of access or lock changes accompanied by threats or intimidation increase the likelihood of criminal charges. A mischief conviction can result in imprisonment for up to 10 years if prosecuted by indictment or 18 months by summary conviction.

Criminal harassment charges under Section 264 of the Criminal Code may apply when lock changes are part of a broader pattern of harassment or intimidation. The offense requires engaging in conduct that causes another person to reasonably fear for their safety, including besetting or watching a dwelling-house. If you change locks and then monitor your spouse's attempts to enter, send threatening communications, or engage in other intimidating behavior, you may face criminal harassment charges carrying a maximum sentence of 10 years imprisonment. Even without a conviction, criminal charges create serious complications in family court proceedings and may result in bail conditions requiring you to vacate the home.

Civil consequences of unauthorized lock changes include court orders requiring immediate restoration of access, cost awards requiring you to pay your spouse's legal fees for bringing a motion, and adverse findings that affect other aspects of your family law case. Courts may draw negative inferences about your credibility and good faith when deciding parenting arrangements, property division, and spousal support. Judges have noted that spouses who resort to self-help measures like changing locks rather than following proper legal processes demonstrate disrespect for the law that influences their overall assessment of the party. The short-term satisfaction of changing locks rarely justifies the long-term legal consequences.

Protecting Yourself and Your Children While Living Together During Divorce

When you cannot legally change the locks but need protection from your spouse, Ontario law provides several alternatives that preserve both parties' possession rights while establishing safety boundaries. A peace bond under Section 810 of the Criminal Code is a court order that protects you by requiring your spouse to keep the peace and be of good behavior, stay away from certain locations you frequent, avoid contact with you or your children, and comply with other conditions. Peace bonds last up to 12 months and violating the conditions is a criminal offense punishable by imprisonment. You can apply for a peace bond at no cost through the criminal court system.

Family court restraining orders provide additional protection while allowing both spouses to remain in the home. Unlike exclusive possession orders that remove one spouse from the home, restraining orders can prohibit specific threatening or harassing behaviors while permitting both parties to occupy the residence. Courts can order your spouse not to contact you except regarding the children, not to attend at your workplace, not to communicate directly except in writing, and not to engage in intimidating or harassing conduct. Violating a restraining order is a criminal offense, and police can arrest the violating spouse without a warrant.

Document all incidents of concerning behavior to support future applications for exclusive possession or other protective orders. Keep a written log with dates, times, and detailed descriptions of incidents. Save text messages, emails, voicemails, and other communications. Photograph any property damage or physical injuries. Identify potential witnesses who observed concerning behavior. If an incident rises to the level requiring police intervention, call 911 immediately and request that officers complete a written report. This documentation becomes critical evidence if you later need to seek emergency exclusive possession or other court protection.

Impact on Children and Parenting Arrangements

Changing locks during divorce can significantly harm your position in parenting disputes because courts view such actions as demonstrating poor judgment and disregard for legal processes. Ontario courts prioritize parenting arrangements that serve the best interests of the child under the federal Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 16.1. A parent who unilaterally changes locks and excludes the other parent from the family home demonstrates a willingness to make major decisions without considering the other parent's rights or the children's need for stability. This behavior may cause courts to question your ability to facilitate a positive relationship between the children and their other parent, a key factor in parenting decisions.

Children experience significant stress when one parent locks the other out of the family home. The sudden exclusion of a parent disrupts the children's sense of security and normalcy during an already difficult transition. Courts recognize that children benefit from maintaining strong relationships with both parents and that parental conflict harms children's emotional wellbeing. If you change locks without legal authority, you may be seen as prioritizing your own interests over your children's need for continued access to both parents. Conversely, if your spouse changes locks and denies you access to your children, document the denial immediately and seek urgent court relief to restore your parenting time.

The parent who remains in the matrimonial home often has an advantage in parenting disputes because courts prefer to maintain the status quo for children. This preference reflects research showing that stability benefits children's adjustment to their parents' separation. If you are seeking primary parenting time, maintaining your residence in the family home strengthens your position. However, this advantage should never be pursued through illegal means like changing locks. Instead, focus on demonstrating your commitment to the children's wellbeing, maintaining their routines, supporting their relationship with the other parent, and working cooperatively toward a parenting arrangement that serves their best interests.

Frequently Asked Questions About Changing Locks During Divorce in Ontario

Can my spouse legally lock me out of our house during separation in Ontario?

No, your spouse cannot legally lock you out of the matrimonial home during separation without your written consent or a court order for exclusive possession. Section 19(1) of the Ontario Family Law Act grants both spouses equal possession rights regardless of whose name is on the title. If locked out, call police with proof of marriage and residence, or file an urgent motion seeking restoration of access. Courts typically order the lock-changing spouse to provide keys within 24-48 hours and may award legal costs against them.

What if I own the house solely in my name—can I change the locks then?

No, ownership does not determine possession rights for a matrimonial home in Ontario. Even if you are the sole owner and purchased the property before marriage, your spouse has equal possession rights under Section 19 of the Family Law Act. The law specifically separates ownership from possession to protect both spouses' housing stability during separation. You must obtain an exclusive possession order or signed separation agreement before changing locks, regardless of title.

How quickly can I get an exclusive possession order in Ontario?

In domestic violence or emergency situations, Ontario courts can grant exclusive possession orders on the same day the application is filed. Emergency orders typically last 14-30 days pending a full hearing. For non-emergency situations, obtaining an exclusive possession order takes 2-6 months depending on court schedules and complexity. The application must be filed in Superior Court of Justice with a $224 filing fee, plus $280 for motions. Courts grant these orders reluctantly and require evidence of extraordinary circumstances.

What happens if I change the locks anyway—what are the consequences?

Changing locks without legal authority can result in criminal charges for mischief under Section 430 of the Criminal Code, carrying up to 10 years imprisonment. Civil consequences include court orders requiring immediate key provision, cost awards for your spouse's legal fees, and negative findings affecting parenting and property decisions. Courts have ordered lock-changing spouses to pay thousands in legal costs and have drawn adverse inferences about their credibility and judgment in other family law matters.

Can I change locks if my spouse has been violent toward me?

Domestic violence strengthens your application for an emergency exclusive possession order, which you can obtain within hours when safety concerns exist. Once granted, you can legally change locks and your spouse must vacate immediately. Do not change locks before obtaining the order, as this may complicate your legal position even in domestic violence situations. Call 911 if in immediate danger, then seek emergency exclusive possession through the Superior Court of Justice.

What if my spouse voluntarily moves out—can I change the locks?

Voluntary departure does not terminate your spouse's equal possession rights under the Family Law Act. Even after moving out, your spouse retains the legal right to return to and enter the matrimonial home unless you have a signed separation agreement or court order stating otherwise. Changing locks after voluntary departure still violates possession rights and exposes you to the same consequences. Document your spouse's departure and seek a written agreement addressing possession before changing locks.

How much does it cost to apply for exclusive possession in Ontario?

The application filing fee is $224, with additional fees of $280 for motions and $280 for case conferences. Total legal costs for obtaining exclusive possession typically range from $5,000 to $15,000 depending on whether the matter is contested. Fee waivers are available if you receive Ontario Works, ODSP, or meet low-income thresholds—the full $224 provincial fee is waived but the $10 federal fee remains. The total cost of a complete divorce proceeding is $679 in court fees ($669 provincial + $10 federal).

Does changing locks affect who gets the house in the divorce?

Changing locks does not determine property division outcomes, which are governed by equalization of net family property under the Family Law Act. However, unauthorized lock changes create negative impressions that can influence judicial discretion in contested matters. More significantly, lock changes often entrench the status quo—the spouse remaining in the home may have practical advantages in property division negotiations. Courts consider all circumstances including each party's conduct when making discretionary decisions about property.

Can common-law partners change locks on shared property?

Common-law partners are not protected by the matrimonial home provisions of the Family Law Act and cannot apply for exclusive possession under Section 24. Possession rights for common-law partners depend on ownership—if you own the property, you generally can change locks, though your partner may have claims to recover belongings. If your partner owns the property, you have no statutory possession rights. Common-law partners experiencing violence should seek restraining orders rather than exclusive possession orders.

What should I do if I need to retrieve belongings from the home after being locked out?

Contact police to request a civil standby while you retrieve personal belongings from the home. Provide documentation of your marriage and former residence at the property. If your spouse refuses entry even with police present, file an urgent motion seeking court-ordered access to retrieve belongings. Document what items you need and their locations. Courts routinely order supervised access to retrieve personal effects, often with police attendance to ensure compliance and prevent conflict.
