Law360 Canada (September 15, 2026, 2:49 PM EDT) -- The Sept. 1 amendment to Ontario’s Rules of Civil Procedure is narrow in wording but broad in effect. Ontario Regulation 275/26 now requires the person signing the statement in a factum to certify not only that every cited authority is authentic, but also that every quotation accurately reproduces its source text. It also adds a quotation-accuracy statement to expert reports under Rule 53.03.
The change matters because quotation verification is now an express filing checkpoint, not merely an assumed drafting practice.
The amendment is technology-neutral. It neither requires disclosure of every use of generative AI nor prohibits AI-assisted drafting. A quotation can change through copying, editing, optical character recognition, a research platform, a drafting tool or human error. The rule focuses on the filed result: whether words presented as a quotation accurately reproduce their source. Its significance therefore extends beyond any one technology cycle.
The distinction from authenticity matters. Since Dec. 1, 2024, Rule 4.06.1 has required a factum to include a signed statement that the signer is satisfied as to the authenticity of every cited authority. Ontario Regulation 275/26 adds a separate inquiry. Authenticity asks whether the authority is genuine; quotation accuracy asks whether the quoted words are actually there. A genuine case maybe quoted inaccurately, while an exact quotation may still be used for a proposition the authority does not support.
That makes the amendment a workflow issue. The rules prescribe the certification, but not one internal method for reaching the required satisfaction. A quotation may be correct when inserted, shortened during editing, moved to another proposition and then survive into the filing version. The practical challenge is maintaining verification as a document moves among researchers, drafters, reviewers and the signer.
Start with source discipline. Where possible, the reviewer should open the authority from a source the rules already treat as presumptively authentic, including a government source, a court website or a commercial publisher of court decisions. A link supplied by a colleague, client, research system or drafting tool can be useful, but it should be a route to verification, not a substitute for reviewing the source.
The next step is direct comparison against the filing version. Every quotation should be located in the underlying authority and compared with the words that will actually be filed. Small edits matter. An omitted qualifier, changed punctuation, misplaced ellipsis or quotation mark left around a paraphrase can alter meaning. A check against an earlier draft may therefore say little about a later version. The useful question is whether the quotation is correct when the document is signed.
Proposition checking should remain separate. Ontario Regulation 275/26 does not create a new certification that every authority supports every proposition for which it is cited. Literal quotation accuracy is not the same as sound legal use. A quotation can be exact while the surrounding reasoning, procedural posture or limiting language changes its significance. In practice, reviewers should distinguish three questions: Is the authority authentic? Is the quotation exact? Does the authority support the proposition advanced? The third remains a matter of professional legal judgment, not a new certification.
Traceability can make that process more reliable without turning it into bureaucracy. The rules do not require a forensic audit trail for every factum. A modest record of who checked the quotation, when and against which version may be enough. A document-management field, closing checklist or verification table can connect the review to the final filing version, giving the signer a clearer basis for certification and the firm a control it can test.
Expert reports require a related but distinct approach. Rule 53.03 already contains authenticity requirements, subject to stated exceptions, and Ontario Regulation 275/26 adds a signed statement that the expert is satisfied that every quotation from an authority, document or record appearing in the report accurately reproduces that material. Experts may work with scientific literature, technical records, industry materials, documents supplied by counsel and sources outside case-law databases.
Counsel and experts should decide early how materials will be verified, while ensuring the expert remains independently satisfied before signing the report.

The management lesson is simple. Firms do not necessarily need another broad technology policy. They need a filing control that survives drafting pressure. My preferred sequence is five steps: open the authoritative or presumptively authentic source, verify the citation, compare each quotation word for word, test whether the cited material supports the proposition, and record the reviewer against the final version. Those steps support the certification process; proposition checking remains an
additional professional safeguard rather than a requirement newly created by Ontario Regulation 275/26.
Ontario’s Sept. 1 amendment is modest in wording but significant in operation. It separates the existence of an authority from the accuracy of the words attributed to it and makes that distinction part of the filing process. Its value is not tied to one technology or one category of error. It asks litigation teams to examine a familiar but often invisible step: how a quotation moves from source to signed filing. That is a practical question worth answering before the next deadline, not after it.
