Redacting a Court Document in Canada: What the Rules Actually Require

Why Court Document Redaction Is Different From Everything Else

When a document is filed with a Canadian court, it generally becomes part of the public record. Court files are accessible — to parties, to the media, to researchers, and to anyone else who makes the request. The privacy calculus is fundamentally different from other document sharing: you're not controlling distribution to a known recipient, you're making information permanently accessible to an unknown audience.

The rules governing what must be redacted from court documents reflect this. They're not based on PIPEDA — courts have their own procedural rules about personal information in filed documents, separate from privacy legislation. But the obligations they create are real and enforceable, and violations have consequences ranging from judicial criticism to procedural orders to professional conduct implications for lawyers who file non-compliant documents.

Federal Court Rules

The Federal Court Rules contain specific provisions about personal information. Rule 152 governs the protection of personal information in documents filed with the court. It requires that the following identifiers be omitted from or redacted in documents filed with the court: the date of birth of any person (use the year of birth only), the personal information number of any person (which includes SINs and other government identifiers), the name of any person known to be a minor, the account number of any financial instrument, and the record of any criminal conviction of any person.

The mechanisms for compliance under the Federal Court Rules include: omitting the information entirely and replacing it with a description, filing the document in a sealed record, or filing a public version with redactions alongside an unredacted version in a sealed file.

What catches litigants off guard: the rules apply to exhibits as well as pleadings. A contract filed as an exhibit that contains the SINs of the parties, a financial statement with banking details, a medical record with a health card number — all of these must be redacted before filing even if they're exhibits the parties consider routine.

Provincial Variations

Ontario: The Rules of Civil Procedure and the Family Law Rules both contain provisions for the protection of personal information. Family proceedings are subject to stronger restrictions — names of minor children and certain financial information in family proceedings may be redacted by default or subject to sealing orders. The Succession Law Reform Act and related proceedings in the Estates List have additional considerations for personal information about deceased persons and beneficiaries.

British Columbia: The Supreme Court Civil Rules include provisions for the filing of confidential information. The Court of Appeal Rules address sealed records. The Family Law Act provides that certain financial disclosure documents — which contain extensive personal and financial information — are protected from public access by default in family proceedings.

Quebec: Quebec's Code of Civil Procedure addresses the protection of personal information in legal proceedings specifically in the context of Law 25. The CAI can receive referrals from courts about privacy matters arising in proceedings. Quebec's rules around protection of personal information in court proceedings are evolving in the context of Law 25 implementation.

Where Litigants and Lawyers Get It Wrong

Not reviewing exhibits before filing. The most common failure is filing exhibits without review. Parties in commercial litigation produce large volumes of documents in discovery, and the documents eventually filed as exhibits are often drawn from that production. Production review is done for relevance and privilege — not always for personal information redaction. The SIN in a customer file produced in a commercial dispute doesn't get redacted because nobody's job was to look for it.

PDFs with inadequate redaction. A PDF redaction that looks correct but hasn't been applied properly — where the "redacted" content is actually just a black rectangle layered over visible text — is no redaction at all. The underlying text is still there, accessible to anyone who copies the text layer or removes the overlay. Proper PDF redaction burns the redaction into the document, destroying the underlying content. Many lawyers and their administrative staff don't know the difference.

Metadata in filed documents. Court documents often carry metadata from the word processing environment in which they were drafted — revision history, author information, tracked changes that were accepted rather than removed, comments. Filing a document without stripping metadata can disclose information about the litigation strategy, the drafting process, and communications that were never intended to be filed.

Forgetting court reporter transcripts. Trial transcripts and examination transcripts filed with the court contain whatever was said during the proceeding. If a witness provided their SIN for identification purposes, if a party described their banking details during cross-examination, if health information was disclosed through testimony — all of that is in the transcript. Filing an unredacted transcript with this information makes it public.

Practical Compliance for Legal Practice

A document review checklist for personal information before court filing should check for: government identifiers (SIN, health card numbers, passport numbers, driver's licence numbers), financial account information (account numbers, routing numbers, credit card numbers), dates of birth (replace with year of birth), names of minors, and criminal records of any person.

For exhibits, the check should extend to embedded metadata, OCR'd content in scanned documents, and financial statements or tax documents that routinely contain the full complement of personal identifiers.

The effort to do this systematically before filing is considerably less than the effort to remedy a filing after the fact — which may require a motion to seal or amend the public record, court approval, and in some cases individual notification to the people whose information was inadvertently made public.
