How to File for Divorce in Mississauga: A Step-by-Step Guide

Published on November 7, 2025
Navigating the divorce process in Mississauga can feel overwhelming, especially during an emotionally challenging time. Understanding the step-by-step procedure for filing for divorce in Ontario is crucial for anyone considering ending their marriage.
This comprehensive guide will walk you through every aspect of the divorce process in Mississauga, from initial considerations to the final decree, ensuring you have the knowledge needed to make informed decisions.
Understanding Divorce Laws in Ontario
Before diving into the procedural steps, it’s essential to understand the legal framework. Canada operates under a no-fault divorce system, meaning you don’t need to prove wrongdoing by your spouse to obtain a divorce. The Divorce Act is federal legislation that sets out the grounds and procedures.
Grounds for Divorce in Ontario
In Ontario, there is only one ground for divorce: the breakdown of the marriage. This breakdown can be established in one of three ways:
- One-Year Separation: You have lived separate and apart for at least one year. This is the most common ground.
- Adultery: Your spouse has committed adultery.
- Cruelty: Your spouse has treated you with physical or mental cruelty, making it impossible to continue living together.
Most people use the one-year separation, as it doesn’t require proving fault and is generally less contentious. You can file your application *before* the year is up, but the court will not grant the divorce until the 12-month period is complete.
What “Separation Under the Same Roof” Means
The one-year separation period doesn’t necessarily mean you must live in different homes. You can be considered separated while living under the same roof if you’ve stopped living as a married couple. This means:
- Sleeping in separate bedrooms
- No longer sharing meals or household chores
- Not attending social functions together
- Living separate lives within the same household
Residency and Court Jurisdiction in Mississauga
To file for divorce in Ontario, at least one spouse must have been “ordinarily resident” in Ontario for at least one year immediately before filing the application.
Mississauga falls under the jurisdiction of the Superior Court of Justice for the Central West Region. The courthouse handling family law matters in Mississauga is located at:
Mississauga Courthouse
Superior Court of Justice
7755 Hurontario Street, Brampton, ON, L6W 4T1
Note: While the courthouse is geographically in Brampton, it serves the entire Peel Region, including Mississauga.
Before You File: The Separation Agreement
A divorce legally ends your marriage, but it does not settle issues like property division, spousal support, or child custody. These issues are typically handled in a Separation Agreement.
A Separation Agreement is a legally binding contract that you and your spouse create. It is highly recommended to have a Separation Agreement drafted by a lawyer *before* you file for an uncontested divorce. This ensures all financial and parental matters are resolved, making the divorce application a simple, final step.
The 7-Step Process for Filing a Divorce in Mississauga
Step 1: Determine Your Type of Divorce
The first step is to determine if your divorce will be contested or uncontested.
- Uncontested Divorce (Simple Divorce): This occurs when both spouses agree to the divorce and have resolved all issues (property, support, children). This is the fastest, cheapest, and least stressful path.
- Contested Divorce: This occurs when spouses cannot agree on one or more issues. This requires court intervention and can significantly extend the timeline and cost.
You can also file a Joint Divorce Application, where both spouses sign and file the paperwork together. This is only for uncontested divorces.
Step 2: Gather Required Documents
Before completing your application, you will need several key documents:
- Original Marriage Certificate: This is mandatory. If you were married outside of Ontario, you’ll need the original certificate from that jurisdiction.
- Separation Agreement (if you have one): This shows the court you have settled your other issues.
- Financial Statements (Form 13 or 13.1): Required if there are any claims for support or property division.
- Children’s Information: Birth certificates and details on living/support arrangements.
Step 3: Complete the Divorce Application (Form 8A)
The main document to start your divorce is Form 8A (Application – Divorce). This form requires detailed information about:
- Both spouses (names, addresses, dates of birth)
- Details of the marriage (date and place)
- Information about any children
- The grounds for divorce (e.g., one-year separation)
- The relief you are seeking (e.g., a divorce, spousal support, child support)
Step 4: File Your Application with the Court
Once your application is complete, you must file it with the Superior Court of Justice.
Filing In-Person: You can file your documents at the family court counter at the Hurontario Street courthouse.
Filing Online: Ontario now offers an online portal to file for divorce. You can submit your Form 8A and other documents electronically. This is often faster and more convenient.
Filing Fees: You must pay the court filing fee, which is approximately $669 (as of late 2025). This is typically paid in two installments:
- $224 when you file your initial application (Form 8A).
- $445 when you file your final documents (Form 36, Affidavit for Divorce).
Once filed, the court clerk will “issue” your application and assign a court file number.
Step 5: Serve Your Spouse (For Sole Applications)
If you filed a sole application (not a joint one), you must “serve” your spouse with a copy of the issued documents. Service is the formal process of delivering the documents.
- This must be done by someone other than you (e.g., a friend, family member, or professional process server).
- Service can be done in person, by mail, or by courier.
- The person who serves the documents must complete an Affidavit of Service (Form 6B), which you must file with the court.
Your spouse has 30 days (if served in Canada) to file a response.
Step 6: Wait for Response or Proceed Uncontested
If your spouse files an Answer (Form 10) and disagrees with your claims, the divorce becomes contested.
If your spouse does not file an Answer within the deadline (or if you filed a joint application), you can proceed as an uncontested divorce. You will file your final set of documents, which includes:
- Affidavit for Divorce (Form 36): A sworn statement confirming all the facts in your application.
- Draft Divorce Order (Form 25A): The final order you want the judge to sign.
Step 7: Obtain Your Final Divorce Order
In an uncontested divorce, you will likely not have to go to court. A judge will review your application and all supporting documents. If everything is correct and the judge is satisfied that all legal requirements are met (especially regarding children), they will sign the Divorce Order.
Your divorce is not final yet. The Divorce Order becomes legally effective 31 days after it is signed by the judge. This 31-day period is for appeals.
After the 31 days, you are legally divorced and can request a Certificate of Divorce from the court. This certificate is the official proof of your divorce and is required if you plan to remarry.
What to Expect in a Contested Divorce
If your divorce is contested, the process becomes much more complex and lengthy. It will involve several additional steps:
- Mandatory Information Program (MIP): Both parties must attend a session that explains the family court process.
- Case Conferences: Meetings with a judge to identify issues, explore settlement options, and set timelines.
- Settlement Conferences: A conference focused specifically on helping you and your spouse settle the issues without a trial.
- Trial: If no settlement is reached, your case will go to trial, where a judge will make final decisions on all disputed matters.
Contested divorces can take 12-24 months or more and cost thousands of dollars in legal fees.
Divorce Timelines & Costs in Mississauga
How Long Does a Divorce Take?
- Uncontested Divorce: Typically 4-6 months from the date you file your final documents, assuming all paperwork is correct.
- Contested Divorce: Can take 12 to 24 months, or even longer, depending on the complexity of the issues and court backlogs.
Remember, these timelines are in addition to the mandatory one-year separation period.
How Much Does a Divorce Cost?
- Uncontested Divorce: The minimum cost is the court filing fee (approx. $669). If you hire a lawyer for document preparation or review, this can add $800 – $2,500.
- Contested Divorce: This is much more expensive. Costs can range from $10,000 to $50,000 or more, depending on how long the disputes last.
Do I Need a Mississauga Family Lawyer?
While it is possible to represent yourself in a simple, uncontested divorce (a “DIY divorce”), it is strongly recommended to seek legal representation in many situations. You should hire a lawyer if:
- Your divorce is contested.
- There are significant assets, properties, or pensions to divide.
- There are disputes about child custody or parenting time.
- There are allegations of domestic violence or child protection concerns.
- Your spouse has hired a lawyer.
A family lawyer ensures your rights are protected and that all documents are correct. Many lawyers offer “unbundled services,” allowing you to hire them for specific tasks (like drafting a Separation Agreement or reviewing your forms) to help manage costs.

Frequently Asked Questions
Can I file for divorce online in Mississauga?
Yes, Ontario offers an online filing portal for divorce applications. You can file a simple (sole) application or a joint application online. For a joint application, the entire process can be completed online. For a simple/sole application, you must still formally serve the divorce papers to your spouse using traditional methods (e.g., in person, by mail).
What is the difference between a Separation Agreement and a divorce?
A Separation Agreement is a legally binding contract that you and your spouse create to settle issues like property division, spousal support, and child custody. A divorce is the legal court order that officially ends the marriage. You do not need a Separation Agreement to get a divorce, but it is highly recommended to have one to finalize all other issues.
How much does a simple divorce cost in Mississauga?
The mandatory court filing fees for a divorce in Ontario are approximately $669 (as of late 2025). This is typically paid in two installments: $224 when you file your application (Form 8A) and $445 when you file your Affidavit for Divorce (Form 36). This does not include legal fees for a lawyer, which can range from a few hundred dollars for document preparation to thousands for a contested case.
What happens if my spouse ignores the divorce papers?
If you have properly served your spouse with the divorce application and they do not file a response (Form 10 – Answer) within the 30-day deadline (in Canada), you can proceed with an uncontested divorce. This is sometimes called a ‘divorce by default.’ You can file your Affidavit for Divorce and other final documents to have the court grant the divorce without your spouse’s participation.
Do I need a lawyer for an uncontested divorce in Mississauga?
While you are not legally required to hire a lawyer for a simple, uncontested divorce, it is highly recommended. A family lawyer can ensure your documents are filed correctly, your rights are protected, and any agreements (like a Separation Agreement) are fair and legally sound. Many lawyers offer ‘unbundled services’ to just review your paperwork at a lower cost.
How long is the 1-year separation period?
The one-year separation is the most common ground for divorce. It means you and your spouse must have lived ‘separate and apart’ for at least 12 consecutive months before the court can grant your divorce. You can file your application *before* the year is over, but the divorce order will not be signed until the full year has passed.
Can we be ‘separated’ but live in the same house?
Yes. You can be considered ‘separated’ while living under the same roof if you are no longer living as a married couple. This means sleeping in separate rooms, managing finances separately, not sharing meals, and not attending social functions together. You will have to provide evidence of this in your affidavit.
When am I officially divorced and able to remarry?
Your divorce becomes legally effective 31 days after the judge signs the Divorce Order. You are not officially divorced on the day the judge signs it. After this 31-day period, you can request a ‘Certificate of Divorce’ from the court, which is the official proof you need to remarry.
Who gets the matrimonial home in a divorce in Ontario?
Under Ontario law, both spouses have an equal right to *possession* (the right to live in) the matrimonial home, regardless of whose name is on the title. The division of the home’s *value* (its equity) is a separate issue, calculated under property division rules. A court can make an order for ‘exclusive possession’ for one spouse in certain circumstances, but this does not change the ownership or value-sharing.
What is Form 8A (Application – Divorce)?
Form 8A (Application – Divorce) is the primary court document used to start a divorce proceeding in Ontario. It’s where you provide the court with information about you, your spouse, your marriage, any children, and the grounds for your divorce (e.g., one-year separation). You can file this as a ‘sole’ application (by yourself) or a ‘joint’ application (with your spouse).
