Affidavit of Service in Toronto: A Step-by-Step Guide
An affidavit of service in Toronto is a sworn record describing how legal documents were served. It can help prove that service took place and provide the court with details about the delivery. In Ontario, the affidavit must follow the requirements that apply to the proceeding and be based on accurate facts.
Step 1: Understand What an Affidavit of Service in Toronto Records
An affidavit of service in Toronto is completed by the person who served the documents. It records facts such as who was served, what was served, when service occurred, where it occurred, and how the documents were delivered.
Under Ontario’s Rules of Civil Procedure, an affidavit used in a proceeding must follow specified requirements. It must be expressed in the first person, identify the deponent, use numbered paragraphs, and be sworn or affirmed before an authorized person.
Read the current Ontario Rules of Civil Procedure (O. Reg. 194) before preparing an affidavit for a court proceeding.
Step 2: Record the Service Details Accurately
When preparing an affidavit of service in Toronto, record the facts while they are fresh.
Depending on the matter, the record may include:
- The name of the person served
- The documents delivered
- The date and time of service
- The location of service
- The method used to serve the documents
- Relevant facts describing how service occurred
The affidavit should contain facts within the deponent’s personal knowledge, unless the applicable rules provide otherwise.
Avoid guessing or adding information that the server did not personally observe.
Step 3: Complete and Swear the Affidavit
An affidavit of service in Toronto is not simply a document that the server signs. The affidavit must be sworn or affirmed in accordance with the applicable requirements.
Ontario states that a commissioner for taking affidavits or notary public can administer an oath or affirmation. Lawyers and paralegals in Ontario are also automatically commissioners for taking affidavits.
Ontario also permits remote administration of oaths or declarations when the conditions under the applicable regulation are met.
Do not sign an affidavit before confirming how it must be sworn or affirmed for your matter.
Step 4: Check the Affidavit Before Filing
Before filing an affidavit of service in Toronto, check every detail against the server’s records.
Look for:
- Correct names
- Correct dates and times
- Accurate service location
- Clear description of the service method
- Complete paragraphs
- Required signatures and jurat
- Properly identified exhibits, where applicable
Ontario’s rules contain requirements for exhibits referred to in affidavits. Some exhibits must be attached and filed with the affidavit.
[CONFIRM] From our operating experience, one of the most common problems is a mismatch between the server’s notes and the final affidavit. Checking the details before swearing can help prevent avoidable corrections.
Step 5: File the Affidavit Correctly
An affidavit of service in Toronto may need to be filed with the court as part of the proceeding. The exact filing process depends on the court and type of matter.
Do not assume that preparing the affidavit completes the process. Check the applicable court’s current filing requirements and keep copies of the completed documents.
If you are unsure about a procedural requirement, consult the court or a licensed Ontario lawyer or paralegal. A process serving company can assist with service and related document handling, but it does not provide legal advice.

Avoid Common Affidavit of Service Mistakes
Errors in an affidavit of service in Toronto can create unnecessary procedural problems. Common issues include missing information, unclear descriptions, incorrect dates, incomplete jurats, and improperly handled exhibits.
An affidavit should tell the court what happened without requiring the reader to guess.

When Professional Help With an Affidavit of Service in Toronto Helps
A professional process server can document service attempts and prepare service information for an affidavit of service in Toronto based on what the server personally observed.
This can be useful when the recipient is difficult to locate, several attempts are required, or detailed service records are needed.
The service itself and the affidavit should remain fact-based. Professional assistance does not replace the need to follow the rules that apply to your specific proceeding.
