Documentary discovery is a key step in most Ontario personal injury lawsuits. Early in the litigation process, the parties are required to identify and exchange relevant documents. For injured people pursuing compensation in Ottawa or elsewhere across Ontario, this stage often forms the foundation for a successful personal injury claim.
In a personal injury case, documentary discovery helps each side understand the evidence relating to:
- liability,
- injuries,
- treatment,
- income loss,
- future care needs, and
- damages
Disclosing private documents like tax returns, medical records, or employment files, can understandably feel intrusive for plaintiffs. It doesn’t always feel great sharing intimate details about your life with a stranger. However, under Ontario’s Rules of Civil Procedure, this step is a necessary part of the litigation process.
It is typically in the Plaintiff’s interest to disclose these documents because they are often the foundation of their claim. Well-organized productions can strengthen a plaintiff’s position, narrow the issues in dispute, and support meaningful settlement discussions.
What Is Documentary Discovery?
In Ontario civil litigation, parties must disclose documents that are relevant to the issues in the action. Rule 30 of the Ontario Rules of Civil Procedure defines “document” very broadly. It includes not only paper records, but also electric information.
Ontario Law states that:
“ (a) “document” includes a sound recording, videotape, film, photograph, chart, graph, map, plan, survey, book of account, and data and information in electronic form; and
(b) a document shall be deemed to be in a party’s power if that party is entitled to obtain the original document or a copy of it and the party seeking it is not so entitled. R.R.O. 1990, Reg. 194, r. 30.01 (1); O. Reg. 427/01, s. 12; O. Reg. 132/04, s. 6.”

Each party typically serves an affidavit of documents. This document lists the records in the party’s possession, control, or power that are relevant to the lawsuit.
Some documents may be produced for inspection, while others may be listed but withheld on the basis of privilege. This may include communications with counsel or certain litigation-related materials.
The purpose of documentary discovery is to avoid surprises and prevent parties from hiding important evidence. Ontario’s civil justice system is built on full and fair disclosure.
If you fail to disclose a document that helps your own case, you will generally not be allowed to rely on it later at trial. This is commonly referred to as the “no surprises” rule.
The failure to disclose a document that benefits the other side, may lead to the court:
- ordering you to pay costs
- draw an adverse inference (assuming the undisclosed document would have hurt your case)
- exclude evidence
- strike all of part of your claim or defence
What Documents Must Plaintiffs Produce?
In an Ontario personal injury case, the plaintiff typically produces:
- medical and rehabilitation records,
- hospital records,
- family doctor notes,
- specialist reports,
- prescription records,
- physiotherapy or chiropractic records, and
- documents relating to out-of-pocket expenses.
Where income loss is claimed, documentary discovery usually includes:
- tax returns,
- notices of assessment,
- pay stubs,
- employment records,
- disability benefit records, and
- business records if the plaintiff is self-employed.
If housekeeping, caregiving, or future care claims are advanced, additional supporting documents may be relevant.
What Documents Do Defendants Produce?
Defendants, including insurers and institutional parties, may produce:
- incident reports,
- surveillance footage,
- photographs,
- maintenance records,
- policies and procedures,
- correspondence, and
- expert reports where appropriate.
In motor vehicle accident cases, additional documents may include:
- police reports,
- repair records,
- insurance materials, and
- accident benefit documentation
Why Relevance and Proportionality Matter
Not every document in a party’s possession must be produced. The guiding question is whether the document is relevant to the issues in dispute.
In personal injury litigation, the accident has typically affected almost every aspect of your life – so the disclosure obligation is wide ranging. There are lots of relevant documents.
At the same time, discovery should be proportionate. The scope of production should reflect the:
- amount in dispute,
- complexity of the issues,
- importance of the records to the case.
Overbroad requests can increase cost and delay, while incomplete production can lead to undertakings, refusals motions, adjourned discoveries, or credibility concerns.
Social Media, Photos, and Electronic Evidence
Electronic records are increasingly important in personal injury cases. Photos taken after an accident, text messages discussing symptoms, emails about missed work, fitness tracking data, and social media posts can all become relevant.
Plaintiffs should assume that publicly available online content may be reviewed by opposing parties. Posts showing:
- travel,
- physical activity,
- work,
- hobbies, or
- social events
may be scrutinized, particularly when a plaintiff’s post shows them doing the very things they say they can’t do anymore.
That does not mean an injured person cannot live their life, but the documentary record should be accurate and consistent with the claims being advanced and the plaintiff’s own evidence.
Parties should also avoid deleting or altering potentially relevant records once litigation is anticipated. Preservation of evidence is important. Destruction of relevant documents can create serious litigation problems.
Privilege and Confidentiality
Some documents do not have to be produced, even if they are relevant. Communications between a party and their lawyer are generally privileged. Documents created for the dominant purpose of litigation may also attract privilege. In personal injury cases, this can include:
- certain expert communications,
- investigation materials, and
- legal strategy documents.
Privilege is an important legal protection, but it must be properly claimed and documented.
Why Good Organization Can Strengthen Your Case
Documentary discovery is far more than a procedural formality.
For plaintiffs, a clear record of treatment, expenses, and functional limitations can help demonstrate the impact of the injury.
For defendants, complete records can assist in testing:
- causation,
- mitigation,
- pre-existing conditions, and
- the quantum of damages.
Poor document management can have the opposite effect. Missing records, unexplained gaps in treatment, inconsistent employment information, or late-produced documents can create avoidable disputes and weaken a party’s credibility.
Practical Tips for Plaintiffs During Documentary Discovery
Documentary discovery in Ontario personal injury cases requires early attention. Parties should identify:
- relevant records,
- preserve electronic evidence,
- organize medical and income documents, and
- address privilege carefully.
Addressing potential issues early is almost always easier than dealing with them later in the litigation.
Protect Your Personal Injury Claim During Document Discovery
A thoughtful approach can reduce procedural disputes and help move the case toward resolution. In many personal injury lawsuits, the documentary record is the foundation on which the case is built.
A plaintiff would also be wise to assume that nothing relevant to their case is private. Trying to hide evidence typically ends poorly (see high profile examples like the Conrad Black case, or the SS&C Technologies case).
The defendant has many tools at their disposal to get at your records. It’s unwise to think that you can get away with hiding something.
You should and must let your lawyer know about all documents that may be relevant to your personal injury claim. If you are worried about disclosing a certain document, tell your lawyer and discuss it with them. It’s better to address it early than get caught breaking the rules later.
