Almost every Ontario lawsuit today involves some form of electronic discovery — emails, text messages, shared drives, cloud storage, and sometimes social media posts. Paper files still exist, but the bulk of relevant evidence in most disputes now lives on a server, a phone, or in an inbox.
That shift creates real practical challenges. Digital records multiply fast, get deleted casually, and blend personal and business communications in ways paper never did. Here's how e-discovery generally works in an Ontario civil case, and what to do the moment you suspect a dispute is heading toward litigation.
Why Digital Records Matter in Litigation Today
Ontario's discovery rules require parties to produce relevant documents to each other, and the definition of "document" is broad enough to capture electronic records just as much as paper ones. That means:
- Emails and email attachments
- Text messages and messaging app conversations
- Documents stored on shared drives or in cloud storage
- Internal chat platforms and collaboration tools
- Metadata attached to electronic files (creation dates, edit history, authorship)
Courts don't treat digital evidence as less important simply because it's easy to create and easy to delete — if anything, that makes preserving it properly more important, not less.
Your Preservation Obligations Once a Dispute Starts
A common and costly mistake is assuming preservation duties only begin once a lawsuit is formally filed. In reality, once a dispute is reasonably anticipated — not necessarily started — steps should be taken to preserve potentially relevant records.
- [ ] Suspend routine auto-deletion policies for relevant accounts, folders, or systems
- [ ] Identify who is likely to hold relevant records (not just senior staff — anyone involved in the relevant events)
- [ ] Preserve records in their original electronic format where possible, rather than only printing them
- [ ] Avoid forwarding, editing, or "cleaning up" documents once a dispute is anticipated
- [ ] Get legal advice early if you're unsure whether something needs to be preserved
Deleting or losing relevant electronic records after a dispute is reasonably anticipated can have serious consequences for how a court views your conduct in the case, separate entirely from the merits of the underlying claim.
What Counts as a "Document" for Discovery Purposes
It's easy to think of "documents" as formal letters and contracts, but Ontario's discovery framework treats the concept far more broadly. Relevant electronic material can include:
| Type | Examples |
|---|---|
| Correspondence | Emails, text messages, direct messages |
| Records | Spreadsheets, databases, accounting software exports |
| Communications | Voicemails, recorded calls, chat logs |
| Metadata | Timestamps, authorship, edit history |
| Social media | Posts or messages relevant to the dispute |
If it exists in electronic form and relates to the issues in the case, it's fair game for discovery consideration — subject to the usual limits like privilege and relevance.
Common E-Discovery Challenges
Electronic discovery brings problems paper-based litigation rarely faced:
- Volume — a single email account can contain years of correspondence, most of it irrelevant, that still has to be searched and reviewed.
- Mixed personal and business use — a personal phone or account used partly for business raises questions about how much of it is fair game.
- Deleted or missing records — messages get deleted routinely, sometimes long before anyone thought about litigation, which can raise hard questions about what should have been preserved.
- Format and metadata disputes — the other side may want records produced in their original electronic format (with metadata intact) rather than as printed pages or static images.
Working Out a Practical Approach with the Other Side
Because electronic discovery can spiral into enormous cost if handled carelessly, parties and their lawyers typically discuss a practical approach early in the case — what sources will be searched, using what search terms or date ranges, and in what format documents will be exchanged. Agreeing on this scope early tends to save both sides significant time and expense compared to negotiating it after documents have already been gathered piecemeal.
Frequently asked questions
Do I have to produce my personal text messages in a lawsuit?
If the messages are relevant to the issues in the case, they generally have to be considered for production, even on a personal device — subject to privilege and proportionality arguments. This is a fact-specific area where legal advice matters, especially where personal and business communications overlap.
What if I already deleted relevant emails before I knew about the dispute?
Ordinary deletion that happens before any dispute was reasonably anticipated, as part of a routine and consistently applied practice, is treated differently than deletion after a dispute arises. Talk to a lawyer promptly if you're unsure whether something you deleted should have been preserved.
Does social media count as discoverable evidence?
It can, if it's relevant to the issues in the case. Courts have increasingly treated social media content the same way as other electronic records for discovery purposes.
Who pays for the cost of e-discovery?
Each party generally bears the cost of gathering and reviewing its own documents for production, though the overall approach to costs in the litigation, including any dispute-specific arguments, is something a lawyer should advise on for your case.
