A Plaintiff’s Reply to a Statement of Defence Explained

When is a reply to a defence necessary?

This is the most important question to answer before deciding whether to file a reply, and it is where many plaintiffs make mistakes in both directions: filing replies that were not needed, or failing to file replies that were.

When a reply is necessary

A reply is necessary when the statement of defence raises new material facts that the plaintiff disputes and wishes to specifically address. This includes situations where:

• The defence alleges facts that, if left unaddressed, could be interpreted as accepted by the plaintiff
• The defence raises an affirmative defence (such as limitation period, contributory negligence, or set-off) that the plaintiff wants to specifically respond to
• The defence introduces a version of events that contradicts the plaintiff's claim in ways not already addressed in the statement of claim
• The defence alleges facts that support a positive case the plaintiff wants to make in reply
• The defence raises a point that, if not specifically addressed in a reply, could limit the plaintiff's arguments at trial

When a reply is not necessary

A reply is not required when the statement of defence simply denies the allegations in the claim without raising new material facts. In that situation, the deemed denial rule under Ontario's Rules of Civil Procedure means the plaintiff's position is already preserved without a formal reply.

Filing an unnecessary reply can create problems. It adds to the court record, may introduce inconsistencies or admissions, and can sometimes narrow the plaintiff's position in ways that were not intended. The decision whether to reply should always be made deliberately, ideally with legal advice.

Deadlines: how long do you have to file a reply?

Under Rule 25.04 of Ontario's Rules of Civil Procedure, a plaintiff has 10 days after service of the statement of defence to serve and file a reply. This is a short deadline that begins running from the date the defence is served, not the date it is received or read.

As with all pleading deadlines in Ontario civil litigation, missing the 10-day window does not automatically bar the reply: a plaintiff can seek consent from the defendant or bring a motion for an extension of time. However, relying on extensions adds procedural complexity and cost. If you receive a statement of defence and are considering a reply, act immediately.

What a reply must and must not include

A reply is governed by the same pleading rules that apply to all pleadings in Ontario under the Rules of Civil Procedure. Getting the content right is important: a reply that oversteps its permitted scope may be struck, and a reply that omits necessary responses can limit the plaintiff's position at trial.

What a reply must include

• A response to each new allegation of material fact raised in the defence that the plaintiff disputes
• Any new affirmative facts the plaintiff relies on in response to new matters raised in the defence
• Clear and specific denials of new facts the plaintiff does not accept
• The plaintiff's version of any new events or circumstances introduced by the defence

What a reply must not include

• Repetition of facts already pleaded in the statement of claim
• Legal arguments or submissions (these belong in factums and at trial, not in pleadings)
• Evidence or documentary details (pleadings contain material facts, not evidence)
• New causes of action not already pleaded in the statement of claim
• Responses to the portions of the defence that simply deny the claim's allegations

Sample reply to statement of defence: annotated structure

The following is an annotated sample showing the format and structure of a reply to a statement of defence in Ontario. This is a generic illustrative example only. It is not legal advice, and a reply in your specific case should be drafted by a litigation lawyer based on the actual pleadings.

Reply to a defence to counterclaim

When a defendant files a counterclaim against the plaintiff, the pleading sequence becomes more complex. Understanding how the reply fits into this extended sequence is important for plaintiffs facing a counterclaim.

The pleading sequence when a counterclaim is filed

When a defendant files a statement of defence that also includes a counterclaim, the plaintiff must serve a defence to counterclaim in addition to any reply to the defence. The defence to counterclaim is the plaintiff's response to the defendant's claims against them, and it follows the same rules as any defence: it must respond to each allegation in the counterclaim, admit what is not disputed, and deny what is.

After the plaintiff serves their defence to counterclaim, the defendant may serve a reply and defence to counterclaim. This document responds to any new facts raised in the plaintiff's defence to counterclaim and sets out the defendant's defence to any claim raised therein. If that document raises new material facts, the plaintiff may in turn need to serve a reply to the defendant's reply and defence to counterclaim.

Key practical points

• The plaintiff's defence to counterclaim and reply to the defence can be served as a single combined document, which is common practice in Ontario
• The same pleading rules apply to all these documents: material facts only, no argument, no evidence
• Each document in the sequence has its own service deadline, and tracking these carefully is essential
• The close of pleadings is the point at which no further pleadings may be served without leave, and it determines when the litigation moves into the discovery phase

Strategic considerations when deciding whether to reply

The decision whether to file a reply involves both legal and strategic considerations. A reply is not always the right move even where one is technically available.

When a reply strengthens your position

A well-drafted reply can crystallize the issues in dispute, prevent the defendant from relying on unchallenged allegations, and ensure the court has a clear picture of the plaintiff's position on every material issue. In complex commercial litigation where the defence raises multiple affirmative defences or introduces a detailed alternative narrative, a reply is usually valuable.

When a reply can create risk

A poorly drafted or unnecessarily detailed reply can introduce admissions the plaintiff did not intend to make, narrow the plaintiff's position in ways that limit arguments at trial, and add unnecessary complexity to the pleadings record. Sometimes the stronger strategic position is to leave the deemed denial rule to operate and address the defence's allegations at the discovery and trial stages rather than through additional pleadings.

This strategic judgment requires familiarity with Ontario pleading rules and the specific facts of the case. It is one of the reasons why consulting a litigation lawyer before deciding whether to reply is time well spent.

Reply to a statement of defence in British Columbia

In BC, the pleading sequence and documents have different names but serve the same functions. The plaintiff's initial document is a notice of civil claim rather than a statement of claim. The defendant responds with a response to civil claim rather than a statement of defence. The plaintiff's reply document is called a reply.

BC's Supreme Court Civil Rules (BC Reg 168/2009) govern the form and content of all pleadings in BC Supreme Court proceedings. The same general principle applies: a reply is used to respond to new facts raised in the response to civil claim, not to repeat the original claim. The deadline for serving a reply in BC is 14 days after service of the response to civil claim.

If you are involved in BC civil litigation and have received a response to civil claim that raises new facts, the same considerations apply: assess whether a reply is necessary, act within the deadline, and consult a litigation lawyer familiar with BC procedure.
