Deleted Snapchat or Dating App Messages in a Sexual Assault Case? A Calgary Criminal Lawyer Explains Why You Must Act Fast

As a criminal lawyer in Calgary who defends sexual offence charges every week, we see the same problem again and again. The messages that could help a client's case were sent on Snapchat, Instagram or a dating app like Tinder, Bumble or Hinge, and they have since been deleted, either by the client, by the other person, or automatically by the app.

This article explains why those messages matter, how the Criminal Code allows an accused person to ask a court for records held by someone else, how quickly the major platforms erase messages, and what you should do today if your message history may be needed in court. If you have been charged, speak with a sexual assault lawyer in Calgary as soon as possible. The evidence you need may disappear within days.

A Common Scenario in Calgary Sexual Assault Cases

Mark and Jenna matched on a dating app and moved their conversation to Snapchat. For several weeks they flirted and made plans. One Saturday they ran into each other at a bar. Mark left first. Around 1:30 a.m., Jenna messaged asking where he went, called him twice, and invited him to come over. He did, and they had sex.

A week later, Mark is charged with sexual assault. In her police statement, Jenna says she barely knew Mark and that he showed up at her home uninvited after the bar.

Mark says the messages tell a different story. The problem: he deleted the chat after a falling-out, Jenna blocked him, or Snapchat erased the messages automatically after they were read.

Why Deleted Messages Can Matter

In Canada, consent must be given at the time of the sexual activity. A prior invitation or a flirtatious history is never consent on its own, and a court will not allow the evidence to be used that way. But if the complainant's account of the relationship, and of how the accused came to be at her home, is contradicted by her own written words, that goes directly to the reliability and credibility of her evidence. In a case that often comes down to one person's word against another's, that can decide the outcome.

The challenge is getting those messages back before they are permanently destroyed.

Getting Records From a Third Party: The Criminal Code Process

When evidence about a sexual offence complainant is held by someone other than the Crown or the accused, such as a social media company, the Criminal Code requires the accused to follow a special application process. Defence lawyers have long called this the "section 278" application. As of July 18, 2026, Bill C-16 (the Protecting Victims Act) renumbered these rules. Third-party production is now governed by sections 278.11 to 278.19.

Is a message history a "record"? A record is anything containing personal information for which there is a reasonable expectation of privacy. In R. v. J.J., 2022 SCC 28, the Supreme Court confirmed that electronic messages between an accused and a complainant can qualify, although more mundane content, like arranging where to meet, often will not. Messages with sexual content can also trigger the separate rules in section 276.

What the application requires:

• It must be brought before the trial judge, not at a preliminary inquiry.
• It must be in writing, identify the specific record and who holds it, and explain why the record is likely relevant to an issue at trial.
• Bare assertions are not enough. The Code says that claiming a record may reveal a prior inconsistent statement, or may relate to the complainant's credibility, is not sufficient on its own. The application needs an evidentiary foundation, usually an affidavit.
• It must be served on the Crown, the record holder (with a subpoena), and the complainant at least 60 days before the hearing.

How it is decided. At a closed hearing, where the complainant may appear with her own lawyer, the judge decides whether the record should be produced to the court for review. The judge weighs the accused's right to make full answer and defence against the complainant's privacy and equality rights. If the judge orders production and reviews the record, the judge then decides whether any part should go to the defence, often with conditions attached.

The timing problem. A trial judge must be assigned, 60 days' notice must run, and two stages of hearings must follow. Realistically, this takes months. Most platforms erase messages in days or weeks.

There is a second obstacle. Snapchat, Instagram and the major dating apps are American companies. U.S. law generally prohibits them from giving the contents of messages to private parties, and they routinely take the position that this applies to criminal defendants, even with a court order. A Canadian production order can be very difficult to enforce against them. By the time an order could be obtained, the data is often gone, and even if it survives, the platform may refuse to release it.

How Long Do Snapchat, Instagram and Dating Apps Keep Your Messages?

Based on each company's published policies (which change often):

• Snapchat deletes chats by default within 24 hours after both people have read them, and unopened messages after about 31 days. Some users set chats to delete immediately after viewing.
• Instagram and Facebook Messenger (Meta) give a 30-day grace period after an account is deleted, and deleted data can take up to 90 days to clear from backups. Many Messenger chats are now encrypted, meaning Meta may never have readable copies at all.
• Tinder keeps account data for about three months after an account is closed.
• Hinge also keeps account data for about three months after closure.
• Bumble allows 28 days to restore a deleted account, after which it starts erasing the data.
• On all three dating apps, unmatching removes the conversation from both users' screens.

The bottom line: even the longest of these windows is shorter than the time it takes to bring a court application. On Snapchat, the window can be as short as a day.

Can You Get the Messages Yourself, or Do You Need a Court Order?

For your own account, you usually do not need a court order. Every major platform lets users download a copy of their own data, such as Snapchat's "My Data" or Meta's "Download Your Information" tool, and the dating apps accept data requests. You can also make a formal request for your personal information under Canadian privacy law. Because you were a party to the conversation, this is often the fastest way to recover it, as long as the platform still has it.

The limits:

• A download only includes what the platform still stores. Messages already purged will not appear.
• If you were blocked or unmatched, or the account was deleted, the conversation may be missing or only your side may appear.
• Encrypted chats may exist only on the phones themselves.

Having the messages is not the same as being able to use them. When an accused wants to use a complainant's private records that he already has, the Criminal Code requires a separate admissibility application with a supporting affidavit, filed at least 60 days before the hearing (sections 278.29 to 278.34). Your lawyer needs to plan for this well before trial.

What you cannot do yourself is force a platform to preserve or release data you can no longer access. Formal preservation requests are a police tool. In Canada, a peace officer can issue a preservation demand for computer data, and the platforms honour law enforcement requests. Your criminal lawyer can ask the Crown and police to preserve and obtain the messages. Police may already have extracted the complainant's phone, and the Crown can disclose communications between the accused and the complainant. A forensic examination of your own phone and cloud backups can sometimes recover messages the app no longer shows.

What to Do Right Now

If you have been charged, or expect to be, and your messages with the complainant matter:

1. Stop deleting anything. Do not delete the app, the account, or any further messages. Do not change auto-delete settings to shorter periods.
2. Download your data today from every platform you used to communicate with the complainant. Save the downloaded files somewhere safe and do not alter them.
3. Preserve your phone and backups. Keep the device, and do not reset it. Existing iCloud or Google backups may contain message data.
4. Send the platform a written request. Write to the platform's privacy or legal team asking it to preserve your account data and the specific conversation, and make a formal request for access to your personal information. Platforms generally act only on law-enforcement preservation requests, so do not rely on this alone, but a dated written request costs nothing, sometimes produces results, and shows you acted promptly.
5. Do not contact the complainant to ask for the messages. Your release conditions almost certainly prohibit it, and doing so can lead to new charges.
6. Call a criminal defence lawyer immediately. Every day matters when the retention window is measured in days. Your lawyer can ask the Crown and police to preserve evidence and plan the applications that will be needed to use it at trial.
