About behaviour
Pseudonymous data
  • User research queries, prompts, and interactions entered by GC employees into the AI assistant at runtime. These queries shape the outputs generated but do not constitute personal information about third parties.

What it is for

Research & DevelopmentEducation & Learning

Lexis+ AI is a pilot AI assistant used by Government of Canada employees at the Department of Justice to help with legal research, drafting, and summarization tasks. It draws on LexisNexis's proprietary legal content — including case law and legislation — to generate text, answer research questions, and summarize documents. The system does not process personal information, and users are informed when AI capabilities are in use.

What it collects and what happens to it

Data taken in

Operational data
Anonymized data
  • Existing proprietary legal publications and datasets from LexisNexis, including case law and legislation. No personal information is included in the data sources.
About behaviour
Pseudonymous data
  • User research queries, prompts, and interactions entered by GC employees into the AI assistant at runtime. These queries shape the outputs generated but do not constitute personal information about third parties.

Processing

Language Models
  • Large language model capabilities underpinning the AI research assistant, drafting, and summarization functions within the Lexis+ AI platform provided by LexisNexis.
Search & Retrieval
  • Semantic search and retrieval over LexisNexis's legal content collection, surfacing relevant case law, legislation, and practical guidance to support user queries.

What it does

Creating (Generative AI)
Human decides
  • Generates draft text, summaries, and legal analysis in response to user queries. GC employee users review and decide what to use or act upon.
Understanding (Semantic AI)
Human decides
  • Retrieves and matches relevant legal content — case law, legislation, and practical guidance — from LexisNexis's proprietary databases in response to research queries.
Deciding (Analytical AI)
Human decides
  • Performs analysis and summarization on legal content, producing structured insights for GC employees who retain final decision-making authority.

Outputs

Generated content
Anonymized data
  • AI-drafted text, summaries, and legal analysis outputs produced by the system in response to GC employee queries. These are advisory outputs reviewed by human users before any action is taken.
A recommendation or prediction
Anonymized data
  • Research results, relevant legal authorities, and suggested analysis surfaced by the AI assistant to guide GC employees in legal work. All recommendations are advisory; human review is required.

How to read the colours

Can it identify you?

Anonymized data
Data about people with the link to who is broken. Stripped of identifiers, blurred, aggregated, or noised so this system can’t reasonably tie a record back to an individual.
Pseudonymous data
Each person’s data is tied to a token (hash, ID, template) that lets this system recognise the same person across events, but the token itself doesn’t reveal a name. Reidentification is possible with extra information.
Identifiable data
The data either contains a direct identifier (name, address, account name, recognisable face or voice, plate number) or carries a token this system uses to look up legal identity during processing.

Who completes the loop?

Human decides
This mode suggests; a person decides what to do next. The AI is always advisory — a human is in the loop on every decision. Example: a triage tool ranks cases for a clinician who chooses which to see first.
Human executes
This mode decides; a person carries out the result. Example: an optimizer plans the day’s trash-collection routes, and drivers run them.
Autonomous
This mode decides and acts on its own. No person reviews each decision or carries out the resulting action.

Definitions from the DTPR standard. Amber is about your data, violet about who decides. The fuller the shape and the deeper the colour, the more identifying the data or the less a person is involved.

Your rights

  • Right to Be Informed of AI UseGC employees are informed when AI capabilities are in use within the Lexis+ AI platform. The register confirms AI use is disclosed to users.
  • Right to Algorithmic TransparencyUsers have access to information about how the AI research assistant functions as part of the pilot evaluation. For more information, contact the Department of Justice Canada.

Risks and safeguards

  • Societal & cultural harmAI-generated legal analysis may contain errors, hallucinations, or outdated content that could mislead GC employees if accepted uncritically.Safeguard: The system is in a pilot evaluation phase; AI use is disclosed to users; outputs are advisory and require human review before any action is taken.
  • Reputational harmIncorrect legal citations or fabricated case law generated by the AI could damage the Department of Justice's credibility if used in official documents without verification.Safeguard: Users are informed of AI use; pilot evaluation ensures controlled deployment; human review is required before outputs are used in official contexts.
