Windsor Courthouses: Where to File, Swear an Affidavit, and What to Bring

Which Windsor court handles your case, counter hours, what you can file online, where to get an affidavit sworn, and how LTB hearings work. Plain English, with an official source for every fact.

Windsor has two provincial courthouses. The one at 245 Windsor Ave. is the Superior Court of Justice building: civil cases, Small Claims, family cases including divorce, enforcement and some criminal matters. The one at 200 Chatham St. E. is the Ontario Court of Justice: criminal, youth and family matters. Provincial offences tickets are handled by the City of Windsor at City Hall, and the Landlord and Tenant Board has no Windsor office, because most of its hearings happen by video. Below is where to go, what you can do online instead, and where to get an affidavit sworn, with a link to the official source for each point.

The City runs provincial offences court administration and prosecution for the Windsor/Essex County court service area. Ontario explains that some Ontario Court of Justice locations are operated by municipalities. Parking tickets are handled separately by the City.

Family cases: which court?

Some Ontario cities have a Family Court Branch that hears every type of family case. Windsor is not on Ontario's list of Family Court Branch locations, so in Windsor the type of case decides the court:

  • Superior Court of Justice (245 Windsor Ave.) hears divorce, division of family property and claims about the family home, as well as parenting, child support and spousal support.
  • Ontario Court of Justice (200 Chatham St. E.) hears parenting time and decision-making responsibility, child support, spousal support, support enforcement, adoption and child protection. It does not hear divorce or property division.

Family Law Information Centres are free across Ontario and give information about separation, divorce and court processes (not legal advice). Ask the family court office where the nearest one is.

What you can file online instead

Outside Toronto, Ontario runs separate online filing portals for each type of case. You need an Ontario.ca Login.

  • Small Claims: Small Claims Court Submissions Online takes most Small Claims documents. Ontario says claims filed on weekdays between 8:30 a.m. and 5 p.m. are processed the same day, and staff review submissions within 3 business days. Filing fees are paid by Visa, Mastercard or debit, and fee waivers are available.
  • Civil (Superior Court): Civil Claims Online issues a statement of claim or notice of action and emails the issued document back. Civil Submissions Online takes other civil documents, reviewed within 3 business days.
  • Family: Family Submissions Online covers both the Ontario Court of Justice and the Superior Court, for example a simple or joint divorce, or an application for child or spousal support.

All three portals exclude the same things: a request for an urgent hearing, documents for a court date 3 business days or less away, and documents needed to meet a deadline 3 business days or less away. For Small Claims, Ontario says those can be filed in person, by mail or by email.

Out-of-town lawyers, note: since October 14, 2025, Toronto-region filings go through the Ontario Courts Public Portal. A Windsor file still uses the portals above.

Where to swear or commission an affidavit

An affidavit has to be signed in front of a commissioner for taking affidavits. Bring identification and the unsigned document, and do not sign it until the commissioner asks you to. Your options in Windsor:

  • Small Claims documents: Ontario's Small Claims guide lists "a Small Claims Court staff member who is a commissioner for taking affidavits (there is no fee for this service)".
  • Family court forms: Ontario's family court guide says "There are commissioners for taking affidavits at all family court offices who will commission your forms for free."
  • Other Superior Court documents: the Superior Court fee regulation (O. Reg. 293/92) sets a fee for taking an affidavit, so expect to pay at the counter for civil affidavits.
  • Lawyers and paralegals: every lawyer and paralegal licensed in Ontario is automatically a commissioner. Each sets their own fee.
  • Community Legal Aid (University of Windsor): the clinic serves low-income and vulnerable people, and affidavits and notarial copies are by appointment only at the Ron W. Ianni Law Building. Call 519-253-7150 to ask whether you qualify.

Before you make the trip, phone 519-973-6620 (or 519-973-6670 for family matters at Chatham St.) to confirm a commissioner will be available during counter hours. Ontario's own commissioner page points court users to the courthouse where they are filing, and notes that ServiceOntario does not commission oaths for certain legal purposes.

Swearing an affidavit by video

Under Ontario Regulation 431/20, an oath or declaration can be taken without being in the same room as the commissioner if:

  • it is done by a method that lets everyone see, hear and talk to each other in real time for the whole transaction;
  • the commissioner confirms the identity of the person swearing;
  • a modified jurat is used that says the oath was taken under the regulation and gives where the commissioner and the person swearing each were at the time;
  • the commissioner takes reasonable precautions, including making sure the person understands what they are signing, and keeps a record of the transaction.

This can help an out-of-town client whose own lawyer commissions the document.

Landlord and Tenant Board matters

The LTB does not list a Windsor office. Its mailing address is in Toronto, and in-person filing is not accepted there. Tribunals Ontario says most LTB mediations and hearings are held by video on Zoom, and you can join by video or by phone. In-person hearings are only scheduled on an approved accommodation request.

To file, use the Tribunals Ontario Portal (it takes L1, L2, L3, L4, L9, L10 and several tenant applications, plus a Certificate of Service after an application is filed), mail or courier, or file in person at a ServiceOntario location that accepts LTB applications. The LTB contact centre is 1-888-332-3234, Monday to Friday, 8:30 a.m. to 5:00 p.m.

Accessibility

Both Windsor courthouses list the same accessibility coordinator: 519-973-6669 or James.Marentette@ontario.ca. Contact the coordinator as early as possible, with the court address, file number, and the date and time of your proceeding, and say what accommodation you need.

When you need a process server

Filing and serving are separate steps. Once a claim, application or notice is ready, it usually has to be delivered to the other side, and the person who delivered it signs proof of that. Rose City Process Servers serves documents across Windsor and Essex County, with a sworn Affidavit of Service included:

We do not draft documents or give legal advice. When your papers are ready, order online or call (226) 773-4813.

Windsor courthouse questions

Which Windsor courthouse handles Small Claims Court?

Small Claims Court is at the Windsor Courthouse, 245 Windsor Ave. (Superior Court of Justice). The phone line is 519-973-6620 and the Small Claims email is Windsor.SCC@ontario.ca. Most Small Claims documents can also be filed online through Small Claims Court Submissions Online.

Can I get an affidavit commissioned for free at the Windsor courthouse?

Ontario's Small Claims guide says a Small Claims Court staff member who is a commissioner charges no fee, and Ontario's family court guide says family court offices commission family forms for free. Other Superior Court affidavits carry a fee set by regulation. Bring identification and the unsigned document, and call ahead to confirm a commissioner is available.

What are the counter hours at the Windsor courthouses?

Ontario lists counter service at both 245 Windsor Ave. and 200 Chatham St. E. on weekdays from 9:00 to 11:00 a.m. and 2:00 to 4:00 p.m. The court offices are open weekdays from 8:30 a.m. to 5:00 p.m.

Where do I file for divorce in Windsor?

Windsor has no Family Court Branch, and the Ontario Court of Justice does not hear divorce or property division, so a divorce goes to the Superior Court of Justice at 245 Windsor Ave. A simple or joint divorce can also be filed online through Family Submissions Online.

Is there a Landlord and Tenant Board office in Windsor?

The LTB does not list a Windsor office. Most LTB mediations and hearings are held by video on Zoom, and you can join by video or phone. Applications can be filed through the Tribunals Ontario Portal, by mail or courier, or in person at a ServiceOntario location that accepts LTB applications.

Can I swear an affidavit by video in Ontario?

Yes, under Ontario Regulation 431/20, if the commissioner and the person swearing can see, hear and talk to each other in real time for the whole transaction, the commissioner confirms identity, a modified jurat records that it was done under the regulation and where each person was, and the commissioner keeps a record.
