  • Almost anything posted publicly, and often content shared privately with a limited audience, can potentially be relevant, including: - Photos and videos showing physical activity,…
  • Setting an account to private, or limiting a post to "friends only," reduces who can see it casually — it does not create a legal shield against disclosure in litigation.
  • Once a dispute is underway, or reasonably anticipated, deleting content connected to it carries real risk — even content that seems embarrassing or unhelpful rather than dishonest.

A photo from a weekend trip. A comment made in frustration. A check-in at a location that contradicts what someone told an insurance adjuster. None of it feels like evidence when it is posted — until a dispute turns into a lawsuit and the other side's lawyer starts looking.

Social media evidence in a lawsuit in Ontario comes up far more often than most people expect, in personal injury claims, employment disputes, family matters, and business litigation alike. Understanding how it gets used — and what not to do with your own accounts once a dispute starts — matters more than many people realize.

What Social Media Content Can Be Used as Evidence

Almost anything posted publicly, and often content shared privately with a limited audience, can potentially be relevant, including:

Courts do not automatically accept everything found online at face value — context, timing, and authenticity still matter — but the content itself is fair game to raise.

Privacy Settings Do Not Make Content Off-Limits

Setting an account to private, or limiting a post to "friends only," reduces who can see it casually — it does not create a legal shield against disclosure in litigation. Ontario courts have generally taken the view that a party cannot simply put content behind a privacy wall and treat it as untouchable, particularly when it appears relevant to the issues in the case.

Why Deleting Posts After a Claim Starts Is Risky

Once a dispute is underway, or reasonably anticipated, deleting content connected to it carries real risk — even content that seems embarrassing or unhelpful rather than dishonest. If it later comes out that relevant posts existed and were removed, a court can view that unfavourably, regardless of the original reason for the post.

The safer approach is almost always to stop posting about the dispute, resist the urge to clean up an account, and speak with a lawyer about what — if anything — needs to be preserved or produced.

What About Posts Made Before the Dispute Existed?

Old posts — vacation photos from years ago, an old comment, a since-forgotten status update — are treated differently than content created or deleted after a dispute began. There is usually no special obligation to preserve every historical post just because a dispute has now arisen. The concern is narrower: do not selectively delete or alter existing content, old or recent, once it looks like it may be relevant to a live or reasonably anticipated claim. If you are unsure whether something old might matter, the safest move is to leave it alone and ask a lawyer rather than deciding on your own that it is irrelevant.

How Opposing Parties Typically Find This Evidence

Lawyers and investigators routinely check public profiles, search for tagged photos and check-ins, and rely on mutual connections or witnesses who may have seen relevant content before it was removed. In some cases, a party can formally request production of specific social media content through the normal document disclosure process in a lawsuit.

Frequently asked questions

Can the other side get a court order for my private social media account?

It is possible in some circumstances, particularly where there is a good reason to believe relevant content exists behind privacy settings. It is not automatic, and courts weigh relevance against privacy concerns case by case.

What if a friend or family member posts about my situation?

That content can still potentially become relevant, even though you did not post it yourself. It is worth being mindful of what people close to you post about an ongoing dispute.

Should I just deactivate my accounts once I'm involved in a lawsuit?

Speak with a lawyer first. Deactivating or deleting an account after a dispute has started can look like destroying evidence, even if that was not the intention, and can create problems that outweigh whatever the account might have shown.

Does this apply to messaging apps too, not just public posts?

Yes. Direct messages and private chats can be just as relevant as public posts, and are subject to the same basic preservation principles.
