Residency requirement:
The federal Divorce Act (s. 3) requires that either spouse have been ordinarily resident in Ontario for at least one year immediately before the application is made. "Ordinarily resident" means your habitual and customary home, not just temporary presence. You may file earlier, but the one-year residency must be met at the time of application.
Filing fee:
$450–$650
Waiting period:
The Canadian Divorce Act requires one year of separation before a divorce order can be granted. There is no additional waiting period after filing — the application can be filed at any time, but the divorce judgment will not issue until the one-year mark. The separation clock starts from the date of living separate and apart.

As of June 2026. Reviewed every 3 months. Verify with your local clerk's office.

Ontario family psychologists recommend waiting a minimum of 6-12 months after divorce finalization before introducing a new partner to your children. Under the Divorce Act, R.S.C. 1985, c. 3, s. 16, Ontario courts evaluate all parenting decisions based on 14 best-interest factors, with the child's physical, emotional, and psychological safety as the primary consideration. While no Ontario law mandates a specific timeline for partner introductions, rushing this process can affect parenting arrangements and create grounds for court involvement if the other parent objects.

When Is the Right Time to Introduce a New Partner to Your Children in Ontario

Ontario child psychologists recommend waiting 9-12 months after divorce finalization before introducing a new partner to children. This timeline allows children to adjust to their new family structure before processing another significant change. The 6-12 month window accounts for healing time, as divorce represents a loss that brings grief for both parents and children.

The recommended timeline begins when the divorce is finalized and physical separation has taken place. Key readiness indicators in children include stable daily routines, curiosity about your social life rather than anxiety, positive communication about both parents, and age-appropriate emotional regulation skills. Children who are still struggling with divorce adjustment should wait longer regardless of the relationship timeline.

A relationship should demonstrate stability before children meet your new partner. Mental health professionals recommend a minimum of 6-9 months of exclusive dating, though relationship stability matters more than any specific timeline. The goal is to avoid introducing children to partners who may exit their lives, creating secondary loss experiences.

Under the 2021 amendments to the Divorce Act, R.S.C. 1985, c. 3, Ontario replaced the terms "custody" and "access" with "decision-making responsibility" and "parenting time" to focus on children's needs rather than parental rights. This shift emphasizes that all decisions affecting children, including meeting new partners, should prioritize the child's best interests.

How to Prepare Your Children for Meeting Your New Partner

Before introducing your new partner to your children, have an open and honest conversation about this new individual entering their lives. Allow children to ask questions and express concerns freely without judgment. This conversation should happen 1-2 weeks before the planned introduction, giving children time to process the information.

The preparation conversation should cover who this person is to you, what the first meeting will involve, and reassurances about your relationship with your children remaining unchanged. Children often fear replacement, so explicit reassurances that your love for them is constant and unconditional help reduce anxiety.

Age-appropriate preparation differs significantly across developmental stages. Children ages 3-5 need simple explanations with reassurance about routine stability. Children ages 6-12 may have more detailed questions about the relationship and future implications. Teenagers often require acknowledgment of their feelings and may need more time to adjust before agreeing to meet a new partner.

Consider your child's current emotional state before proceeding. If they are struggling academically, socially, or emotionally, adding a new relationship dynamic may compound their stress. Ontario courts have recognized that children's adjustment periods vary, and parents should respect individual readiness rather than imposing arbitrary timelines.

How to Plan the First Introduction Meeting

Ontario psychologists recommend holding the initial meeting in a neutral, public place such as a park, restaurant, or activity center. Public settings reduce pressure on everyone involved and provide natural conversation topics through shared activities. Subsequent meetings should be gradual over time in terms of location and activities, progressing from public spaces to more intimate family settings.

Keep the first meeting brief, ideally 1-2 hours maximum. Short initial encounters allow children to form first impressions without feeling overwhelmed. Plan an activity that facilitates interaction without forcing constant conversation, such as bowling, mini-golf, or visiting a zoo.

Do not display physical affection with your partner during initial meetings. Children need time to adjust to seeing their parent with someone new. Introducing romantic elements too quickly can increase children's discomfort and resistance to the new relationship.

Allow your children to set the pace for relationship development. Some children warm up quickly while others need multiple casual encounters before feeling comfortable. Forcing closeness typically backfires, creating resentment rather than bonding. Let children initiate physical contact like hugs rather than expecting or requiring affection.

How to Communicate with Your Co-Parent About New Partner Introductions

While Ontario law does not require formal notification before introducing a new partner to children, informing your co-parent 1-2 weeks in advance reduces conflict and supports your children's emotional security. This advance notice demonstrates good-faith co-parenting and allows your former spouse to prepare for potential questions from the children.

Provide basic information including the partner's first name, general background, and planned introduction setting. You are not obligated to provide extensive personal details, but transparency about the introduction helps maintain co-parenting trust. Consider how you would want to be informed if the roles were reversed.

Existing parenting orders may contain specific provisions about introducing new partners to children or notifying the other parent of significant life changes. Review your parenting plan or court order for any clauses addressing this situation. Violating such provisions could create grounds for a Motion to Change at the other parent's request.

If your co-parent objects to the introduction, attempt to address their concerns through discussion or mediation before proceeding. In Ontario, Family Law Information Centres (FLICs) at local courthouses provide free guidance on navigating parenting disputes. While you generally have the right to make decisions about your children during your parenting time, unnecessarily escalating conflict harms children.

What Parenting Orders May Say About New Partners

Some Ontario parenting orders include specific clauses about introducing romantic partners to children. The AFCC Ontario Parenting Plan Guide and Template, widely used in Ontario family courts since January 2020, recommends that parents address when to introduce significant others as part of comprehensive parenting planning.

Common parenting order provisions may include minimum relationship duration before introduction (often 6-12 months), advance notice requirements to the other parent, overnight restrictions when new partners are present, and introduction protocols specifying public initial meetings. Courts have referenced the AFCC Parenting Plan Guide with approval in multiple Ontario decisions.

If your parenting order does not address new partner introductions, you generally have discretion to make this decision during your parenting time. However, decisions that significantly impact children's emotional wellbeing fall under the broader best interests standard. Courts can intervene if introductions demonstrably harm children.

To modify existing parenting orders, either parent may file a Motion to Change (Form 15) with the Ontario Superior Court of Justice. The filing fee is $224, and the moving party must demonstrate a material change in circumstances that affects the child's best interests. A consensual variation can be finalized within weeks, while contested motions typically take 3-12 months.

When Can Your Co-Parent Legally Object to Your New Partner

Under Divorce Act, R.S.C. 1985, c. 3, s. 16(3), Ontario courts evaluate 14 factors when considering parenting arrangements, with the child's safety as the primary consideration. Your co-parent may seek court intervention if your new partner poses documented safety concerns to children, including criminal history involving violence or children, substance abuse issues, or history of family violence.

The threshold for court intervention is high when the concern is simply disapproval of your dating choices. Ontario courts recognize that parents have personal autonomy during their parenting time. However, if your new partner's presence demonstrably affects children's physical, emotional, or psychological safety, courts can modify parenting arrangements.

If your co-parent files a Motion to Change based on your new relationship, they must prove a material change in circumstances under the test established in Gordon v. Goertz (1996) by the Supreme Court of Canada. The change must: (1) affect the condition, needs, or circumstances of the child; (2) materially impact the child's wellbeing; and (3) have been unforeseeable at the time of the original order.

A new relationship existing in preliminary stages at the time of the original order may not qualify as a material change. Courts apply a particularly high threshold to prevent overburdening the judicial system with immaterial claims and to provide families with stability rather than constant litigation.

What If Your Co-Parent Introduces an Unsafe Partner to Your Children

If you have legitimate safety concerns about a person your co-parent has introduced to your children, document specific incidents and behaviors rather than relying on general discomfort. Ontario courts require evidence, not speculation, when modifying parenting arrangements based on safety concerns.

Under Divorce Act, R.S.C. 1985, c. 3, s. 16(4), family violence is a primary consideration in all parenting decisions. Courts must assess the nature, seriousness, and frequency of violence, whether violence was directed at the child, and the impact on the child's safety. Sole decision-making responsibility is commonly ordered when family violence is established.

To address safety concerns formally, you may file a Motion to Change or seek an urgent motion if circumstances warrant immediate court intervention. Evidence that supports safety-based modifications includes police reports, Children's Aid Society involvement, documented substance abuse, criminal convictions, and professional assessments.

Ontario courts can order various assessments to evaluate safety concerns. Voice of the Child reports cost $1,951-$3,250 on average and take approximately 30 days. Section 30 parenting assessments through private assessors cost $5,086-$10,000 and take 60-120 days. The Office of the Children's Lawyer provides court-funded assessments for qualifying families.

How Remarriage or Cohabitation Affects Existing Parenting Orders

Remarriage alone does not automatically trigger modification of parenting orders. However, the introduction of a new spouse into the household may constitute a material change in circumstances that justifies court review. Ontario courts consider how household changes affect children's stability, relationships, and wellbeing.

If your remarriage involves relocation, this triggers specific notice requirements under Divorce Act, R.S.C. 1985, c. 3, s. 16.9. Parents must provide at least 60 days written notice before a relocation that would significantly affect the child's relationship with the other parent. The relocating parent bears the burden of demonstrating the move serves the child's best interests.

Ontario courts have recognized step-parent relationships and sibling bonds as relevant factors in parenting decisions. In cases involving blended families, courts may consider the child's attachment to step-siblings and step-parents when evaluating parenting arrangements. One Ontario court ruled it was in a child's best interest to maintain a parallel parenting schedule with a biological sibling after a step-parent relationship was established.

Cohabitation agreements cannot determine parenting arrangements for children, as these matters must be decided according to the child's best interests at the time of any dispute. Any provisions in a cohabitation agreement addressing children are subject to court review and modification based on current circumstances.

How to Address Children's Negative Reactions to a New Partner

Children's resistance to new partners is common and does not necessarily indicate the relationship should end. Negative reactions often reflect children's ongoing grief about the divorce, loyalty conflicts, or fear of family changes rather than genuine incompatibility with the new partner. Allow children time to express and process these feelings without forcing acceptance.

Maintain open communication about children's feelings without defending your partner or dismissing concerns. Validate emotional responses with statements like "I understand this is a big change" while reinforcing that your relationship with them remains your priority. Avoid putting children in the middle of adult relationship decisions.

Consider individual or family counselling if children's negative reactions persist beyond initial adjustment periods. Ontario offers various mental health resources for families navigating post-divorce transitions. Divorce counselling at private practices in Toronto and across Ontario typically costs $150-$250 per session, while some community agencies offer sliding-scale fees.

If your co-parent is actively undermining your new relationship with children, this may constitute problematic behaviour under best interests factors. Courts consider each parent's willingness to support the child's relationship with the other parent. Parental alienation tactics can affect parenting arrangements, though Bill C-223 (currently under parliamentary review in 2026) proposes amendments addressing how courts handle alienation claims.

How to Build a Healthy Blended Family Over Time

Successful blended family integration typically takes 2-5 years according to family researchers. Set realistic expectations rather than assuming instant bonding. Focus on building individual relationships between your partner and each child rather than forcing family-wide activities before connections are established.

Allow your new partner to take a supporting role rather than a disciplinary role initially. Children accept step-parent authority more readily when it develops gradually from an established relationship rather than being imposed immediately. Primary discipline should continue coming from biological parents during early integration stages.

Maintain one-on-one time with each child separate from your new partner. Children need reassurance that your relationship with them remains primary despite the new romantic relationship. Schedule regular individual activities that demonstrate continued commitment to your parent-child bond.

Create new family traditions while respecting existing ones. Blended families develop unique identities over time through shared experiences. However, maintaining some traditions from the original family structure helps children feel continuity rather than complete replacement of their former family life.

Frequently Asked Questions

How long should I wait to introduce my new partner to my children after divorce in Ontario?

Ontario child psychologists recommend waiting 9-12 months after divorce finalization before introducing a new partner to children. The relationship should demonstrate 6-9 months of stability before introductions occur. This timeline allows children to adjust to divorce before processing another significant change, and avoids secondary loss if the new relationship ends.

Does Ontario law require me to tell my ex before introducing my new partner to our children?

Ontario law does not require formal notification before introducing a new partner to children. However, best practice is to inform your co-parent 1-2 weeks in advance. This demonstrates good-faith co-parenting and allows your ex to prepare for children's questions. Check your parenting order for any specific notification provisions.

Can my ex stop me from introducing my new partner to our children?

Generally, your ex cannot prevent introductions based solely on disapproval of your dating choices. However, they can seek court intervention if your new partner poses documented safety concerns to children. Under the Divorce Act s. 16, courts can modify parenting arrangements when children's physical, emotional, or psychological safety is at risk.

What should the first meeting between my new partner and children look like?

Ontario psychologists recommend initial meetings in neutral public places such as parks or restaurants. Keep the first meeting brief (1-2 hours) with activity-based interactions like bowling or mini-golf. Avoid displaying physical affection with your partner. Allow children to set the pace for relationship development over subsequent meetings.

Can introducing a new partner affect my parenting arrangements in Ontario?

Introducing a new partner can affect parenting arrangements if it constitutes a material change in circumstances under the Gordon v. Goertz test. Changes must materially affect the child and have been unforeseeable when the original order was made. The filing fee for a Motion to Change is $224, with contested motions taking 3-12 months.

How do I handle my children's negative reactions to my new partner?

Negative reactions are common and often reflect divorce grief or loyalty conflicts rather than genuine incompatibility. Validate children's emotions without dismissing concerns or defending your partner. Maintain open communication and consider counselling if reactions persist. Allow adequate adjustment time before expecting acceptance.

What if my ex introduces someone unsafe to our children?

Document specific safety concerns with evidence such as police reports or professional assessments. Under Divorce Act s. 16(4), family violence is a primary consideration in parenting decisions. File a Motion to Change or urgent motion if circumstances warrant. Courts can order assessments costing $1,951-$10,000 to evaluate safety concerns.

Should my new partner meet my children before we move in together?

Yes, children should have multiple interactions with your new partner over several months before cohabitation. This allows gradual relationship building rather than sudden household integration. Children adjust better when they have established comfort with a new partner before sharing daily living space.

How do I include new partner provisions in my parenting plan?

The AFCC Ontario Parenting Plan Guide recommends addressing new partner introductions in comprehensive parenting plans. Common provisions include minimum relationship duration (6-12 months), advance notice requirements, and introduction protocols. Under Divorce Act s. 16.6(1), courts include parenting plans in orders unless they conflict with children's best interests.

How long does it take for a blended family to feel normal?
