The post is damaging and clearly false. But the name attached to it is a fake, a pseudonym, or just a username with no identifying information. Can you sue someone you cannot identify? And how do you find out who they are?
Suing an anonymous online poster in Ontario is possible, but it requires an additional legal step before you can serve a statement of claim: obtaining a court order that compels the platform, internet service provider, or other third party to disclose the poster's identity. This type of order is called a Norwich order in Ontario practice.
Why Anonymous Posting Creates a Legal Obstacle
To sue someone in Ontario, you must name them in your statement of claim and serve them with court documents. You cannot serve a username or a blank space. Until you know who posted the content, the lawsuit is stalled at the starting line.
The challenge is that platforms and internet service providers (ISPs) hold whatever identity information exists — email addresses, IP addresses, account registration details, phone numbers — and will not hand it over without a legal obligation to do so. A Norwich order creates that obligation.
What Is a Norwich Order?
A Norwich order (named after a UK case that established the principle, adopted into Canadian law) is a pre-litigation disclosure order directed at an innocent third party — the platform or ISP — that requires them to produce identifying information about the anonymous poster.
It is not a judgment against the platform. The platform has done nothing wrong. The order simply compels them to assist you in identifying who did.
What You Must Show to Get a Norwich Order in Ontario
Ontario courts apply a multi-factor test when deciding whether to grant a Norwich order to unmask an anonymous poster. The key considerations are:
1. A valid claim against the anonymous person
You must show that you have a viable cause of action against the unidentified person — typically that the content they posted could be defamatory if the factual allegations in your proposed claim are proven. You do not need to prove the case at this stage, but you need to show it is not frivolous.
2. The anonymous person is the only practical source of the information
If you can identify the poster through other means — a mutual contact, a visible profile photo that is identifiable — you must explore those avenues. Courts grant Norwich orders when the third party (the platform) is the only practical way to get the identifying information.
3. The third party (platform) has the information
There is no point ordering a platform to disclose information it does not have. For major platforms — Google, Meta, Yelp, Reddit, X — they typically hold some account information (registration email, IP address logs for the period at issue). Smaller or older platforms may have deleted logs.
4. Disclosure is not unfair to the anonymous person
Courts balance the plaintiff's right to seek redress against the poster's interest in privacy and free expression. If the alleged defamation is trivial, the privacy interest may outweigh the disclosure interest. If the defamation is serious, the balance tips toward disclosure.
5. Disclosure is proportionate and appropriate
The court considers whether the order is narrowly targeted — seeking only the information needed to identify the person — rather than a broad fishing expedition into the poster's account history.
How the Process Works in Practice
Step 1: Obtain and preserve evidence Screenshot the post and document all available metadata — the username, profile page, posting date and time, any platform badges or identifiers, and the URL.
Step 2: Apply to court Your lawyer brings an application for a Norwich order in Ontario court, supported by an affidavit setting out the defamatory content, the harm suffered, the steps taken to identify the person through other means, and why the platform likely has identifying information.
Step 3: Platform is notified The platform is given notice of the application. Major platforms (Google, Meta, etc.) often have dedicated legal teams that respond to these requests. They may contest the order, comply without objection, or respond that they do not hold the information sought.
Step 4: Court grants or denies the order The court weighs the factors above and either grants or denies disclosure. Courts in Ontario have regularly granted Norwich orders in genuine defamation cases.
Step 5: Identify the poster and serve the claim Once you have identifying information — typically an email address or IP address — your lawyer can investigate further (an IP address leads to an ISP, which may require a second order to identify the subscriber). Once you have a name and address, you can issue and serve the statement of claim.
Limitations and Practical Realities
Platforms may have limited information
A fake email address used to register an account, an IP address routed through a VPN, or a platform that has already deleted its logs can defeat a Norwich order practically even if it is legally granted.
Chain of orders may be needed
An IP address alone identifies the ISP, not the individual. A second order to the ISP for subscriber records may be required. This adds time and cost.
Foreign platforms complicate enforcement
US platforms are subject to Canadian court orders affecting Canadian users, but enforcement varies. Most major platforms respond to properly served Canadian court orders even though they are US-based.
Time-limited logs
Platforms and ISPs do not retain IP logs indefinitely. If too much time passes, the relevant records are gone. Acting promptly is important.
Frequently asked questions
How long does it take to get a Norwich order?
Timeline depends on court scheduling, whether the platform contests the order, and whether follow-up steps (ISP orders) are needed. Simple cases where the platform does not contest may be resolved in a few months — verify current timelines with your lawyer.
Can I get a Norwich order against a foreign platform?
Canadian courts have asserted jurisdiction over foreign platforms that direct services to Canadian users. Major platforms like Google, Meta, and Reddit have responded to Canadian orders. Smaller or less cooperative foreign hosts are more challenging.
What if the platform says the information was deleted?
If the platform deleted the logs before the order was served, the information is gone. This is why acting quickly after discovering defamatory content is so important — the evidentiary window closes.
Is a Norwich order the same as a search warrant?
No. A search warrant is a criminal law tool. A Norwich order is a civil court order in pre-litigation or ongoing civil proceedings. It is directed at a third party who has done nothing wrong, not at the defendant.
