Substitutional Service in Alberta: When You Cannot Serve the Defendant

The Problem: You Filed Your Claim but Cannot Find the Defendant

You paid the filing fee, the registry stamped your Civil Claim, and now you need to serve it. You can hand it to the defendant, leave it at their usual residence with a resident who appears to be at least 16, or use recorded mail signed by the defendant or someone on their behalf. But the defendant has moved, is dodging you, or simply never answers the door.

This is where substitutional service comes in. The Alberta Court of Justice allows you to apply for an order permitting an alternative method of delivery — email, social media, posting to a door, or service on a family member — when conventional methods have genuinely failed.

What Counts as Valid Primary Service

Before seeking a substitutional service order, understand what the Court of Justice normally requires for commencement documents like a Civil Claim (Form CTS1461).

For an individual, service may be made by handing over the claim, leaving it at the defendant's usual residence with a resident who appears to be at least 16, or sending it by recorded mail signed by the defendant or someone on their behalf. For a corporation, approved methods include leaving or sending recorded mail to its registered office, serving a director, or serving a person who appears to have management and control at a qualifying place of business. An extra-provincial corporation is served through its Alberta attorney for service.

For recorded mail to an individual, the defendant or someone signing on their behalf may acknowledge receipt. Keep the receipt and signed acknowledgment for the Affidavit of Service.

Ordinary email, text messages, and regular letter mail are not valid primary service for a Civil Claim. That restriction is exactly why substitutional service orders exist.

How to Apply for a Substitutional Service Order

You need two documents:

1. Application (Form CTS1475) — requesting the court grant an alternate service method
2. Affidavit in Support of Substitutional Service (Form CTS11421) — sworn evidence showing what you tried and why it failed

The affidavit is the critical piece. A Justice will not grant your order unless you demonstrate genuine, documented attempts to serve the defendant through normal channels. Include:

• Dates, times, and results of your attempts to use an approved service method. There is no fixed number of attempts; explain what you tried and why it was unsuccessful.
• If you also attempted recorded mail, include its tracking showing delivery was attempted and returned or unsigned
• Skip-tracing efforts — CORES searches, phone directory checks, social media profiles confirming the person's identity
• Any evidence of evasion — lights on but no answer, vehicles in the driveway, unsigned delivery notices

The affidavit must also propose the alternative method you want the court to approve. Be specific: "service by email to [address] which the defendant uses for business correspondence" or "service on the defendant's adult daughter residing at [address]."

What Alternative Methods Get Approved

The test is whether the proposed method is "reasonably calculated to bring the claim to the defendant's attention." Common court-approved alternatives include:

• Email to an address the defendant actively uses (business email is stronger than a personal address you are guessing at)
• Service on an adult household member at the defendant's last known residence
• Posting to the door of the defendant's residence or business, combined with regular mail
• Social media message (rare, but courts have approved it when other channels are exhausted and the profile is verifiably the defendant's)

A Justice can also combine methods — for instance, ordering email service plus posting to the door.

After the Order: Follow the Terms Exactly

Once the Justice signs the substitutional service order, follow it to the letter. If the order says "serve by email to [email protected] and post a copy to 123 Main St, Calgary," do both. Do not improvise.

After completing substitutional service, file an Affidavit of Service of Commencement Documents (Form CTS11420) proving you followed the order. Attach the order itself and any delivery confirmations (email sent receipts, photos of posted documents, tracking records).

The substitutional service order sets the defendant's response deadline. Follow the number of days stated in the order.

What Happens If the Defendant Still Does Not Respond

If the defendant does not file a Dispute Note within the response period, you can apply for default judgment, just as you would after conventional service. The court treats properly executed substitutional service the same as personal service for procedural purposes.

If you skip the substitutional service application and simply serve the claim by an unauthorized method, you risk having the entire action set aside later — even after obtaining a judgment.
