Affidavit of Service in Ontario: What It Is and Why It Matters

If you have been asked to serve court documents in Ontario, you may eventually hear the term "Affidavit of Service."

An Affidavit of Service is used to provide evidence about how, when, where, and on whom documents were served.

For people involved in litigation, this document can be an important part of demonstrating that service took place.

At Quick Serve and File, we assist lawyers, law firms, businesses, and self-represented individuals with professional process serving and related legal support services throughout Ontario.

What Is an Affidavit of Service?

An Affidavit of Service is a sworn statement setting out details concerning the service of documents.

Depending on the circumstances, it may identify:

  • The person who was served

  • The documents served

  • The date of service

  • The time of service

  • The location of service

  • The method of service

  • Other relevant details concerning the service

The exact requirements can vary depending on the proceeding and applicable court rules.

Why Is an Affidavit of Service Important?

Simply saying "I served the documents" may not be enough.

A properly completed affidavit can provide a formal record of what occurred.

This can become particularly important if the recipient later claims:

  • They were never served

  • They received the documents late

  • They were served at the wrong location

  • The wrong person received the documents

  • The required method of service was not followed

A detailed service record can help establish what actually occurred.

Who Can Prepare an Affidavit of Service?

The person who actually carried out the service may be required to swear or affirm the affidavit, depending on the applicable requirements.

The affidavit should accurately describe what the person knows and observed.

It should not contain assumptions or information that the person cannot properly attest to.

What Information Should Be Included?

The precise information required depends on the proceeding, but service documentation may include:

Date

The date on which service occurred.

Time

The approximate or exact time of service, as appropriate.

Location

Where the documents were served.

Person Served

The identity or identifying information of the person who received the documents.

Documents

The documents that were served.

Method of Service

How the documents were delivered or served.

Circumstances

Any relevant circumstances surrounding the service, including refusal or other unusual events.

Accurate details matter.

What If the Person Refuses to Accept the Documents?

Refusal does not necessarily mean that the process server should simply walk away and consider the assignment finished.

The appropriate response depends on the circumstances and the applicable service rules.

A process server should document what occurred as accurately as possible.

This may include recording the recipient's words, conduct, location, and other relevant observations.

What If Service Was Not Successful?

An unsuccessful attempt should also be documented.

For example, the process server may record:

  • The date and time of the attempt

  • The address visited

  • Whether anyone was present

  • Whether contact was made

  • What was observed

  • Any information obtained during the attempt

This can help the client determine what to do next.

What Happens After the Affidavit Is Completed?

Depending on the proceeding, the affidavit may need to be sworn or affirmed and then filed with the appropriate court or used as evidence of service.

The exact procedure depends on the type of proceeding and applicable court requirements.

If you are self-represented, it is particularly important to understand what your specific court requires.
