Digital Evidence and Data-Driven Discovery In Personal Injury Cases

October 23, 2025, Kitchener, Ontario

Posted by: Robert Deutschmann, Personal Injury Lawyer

In today’s injury claims, digital evidence isn’t just extra information—it can be decisive. From health records to smartphone data and dashcam footage, data can clarify timelines, causation, and the real impact of an injury. If you’re pursuing a personal injury claim in Ontario, understanding how digital evidence works and how a knowledgeable lawyer can use it is essential. Deutschmann de Koning Law can help you build a data-driven case that stands up in court or at the negotiating table.

What counts as digital evidence in Ontario personal injury cases?

• Electronic health records (EHR) and medical data: Detailed treatment histories, imaging, and notes that document the severity of injuries and the need for ongoing care.
• Wearable and device data: Fitness trackers, smartwatches, and medical devices that can provide information about activity levels, sleep patterns, pain episodes, or rehabilitation progress.
• Smartphone and app data: Location history, communication logs, and app usage that can support timelines, accident circumstances, or functional limitations.
• Telematics and vehicle data: In auto-related claims, data from vehicle systems, GPS, speed, braking, and crash data can illuminate how an accident happened and how injuries have affected driving.
• Dashcam and CCTV footage: Video evidence of the incident and post-accident behaviours that corroborate or dispute conflicting accounts.
• Social media and online activity: Posts, photos, and check-ins that may reflect activity levels, mood, or lifestyle changes after an injury.
• Medical device data: Data from implants or pumps that can show usage patterns, malfunctions, or adverse events.

Why digital evidence matters

• Timeline clarity: Data can fill gaps in when injuries occurred, when treatment started, and how recovery progressed.
• Causation and intensity: Objective measurements (like pain scores, activity limits, or functional tests) help demonstrate the real impact of injuries on daily life.
• Damage calculation: Documentation of medical costs, rehabilitation needs, assistive devices, and lost wages is often more precise when supported by digital records.
• Credibility and fairness: Data reduces reliance on memory alone and can level the playing field between individuals and well-funded defendants or insurers.

Navigating privacy, admissibility, and compliance

• Privacy laws in Canada and Ontario: Personal health information and other sensitive data are protected. Lawyers must balance the need for evidence with privacy rights under laws and  provincial health information rules.
• Admissibility and authenticity: Digital evidence must be properly preserved, authenticated, and shown to be relevant and reliable. This often requires expert analysis and a clear chain of custody.

• Risk management: Over-collection or invasive data requests can backfire. A careful, targeted approach helps protect your privacy while obtaining useful information.

How a personal injury lawyer helps you with digital evidence

• Early preservation and strategy: We identify what data will likely matter, implement preservation steps, and avoid spoliation (destroying evidence) that could jeopardise your claim.
• Coordinating technical expertise: We work with digital forensics specialists, medical informatics professionals, and accident reconstruction experts to interpret complex data accurately.
• Tailored discovery requests: We draft precise information requests and search terms to gather relevant data without overreaching or infringing privacy rules.
• Data interpretation for damages: Our team translates raw data into meaningful evidence of medical expenses, disability, and loss of earning capacity.
• Transparent handling of sensitive information: We explain what data is being sought, why it’s needed, and how it will be used, giving you confidence and control over your information.

Practical steps for clients to strengthen a data-driven claim

• Preserve devices and accounts: Avoid deleting messages, restricting location history, or altering data settings after an incident. Keep phones, tablets, wearables, cars, and relevant accounts accessible.
• Document data-related actions: Note when and where data was collected, who accessed it, and any interruptions in data capture (e.g., device downtime).
• Be mindful of privacy boundaries: Share only data that directly supports your claim and is legally permissible. We’ll guide you on what to disclose and how.
• Monitor changes in data sources: If a device or app updates, tell your lawyer so we can assess any new data that could help or hurt your case.
• Communicate health and recovery openly: Digital data is powerful, but it works best when paired with honest medical input and documented treatment plans.
