Legal AI Enters a New Phase in Canada with Rollout of Lexis+ with Protégé

The conversation surrounding artificial intelligence in the Canadian legal sector has fundamentally shifted. No longer a novel concept or a distant future projection, AI has become a baseline reality for modern legal practices. Today, the real challenge facing law firms and corporate legal departments is operational: how to move past isolated, ad-hoc digital experiments and turn generative AI into a dependable, structured part of how legal work actually gets done.

The recent market introduction of Lexis+^® with Protégé^TM in Canada marks a significant evolution in this landscape. By moving the industry away from standalone AI utilities and introducing end-to-end, automated legal processes, this launch represents a major turning point in how the Canadian legal profession applies technology to everyday practice.

The recent market introduction of Lexis+^® with Protégé^TM️ in Canada marks a significant shift in the legal tech landscape, moving the industry away from standalone AI functionality and into a new phase that where AI is woven into the fabric of legal work. This shift is worth paying attention to because it marks an important turning point in how the Canadian legal profession is applying the technology to legal practice.

The Limits of the Ad-Hoc Approach

The first wave of legal AI adoption was defined by the prompt. A lawyer would open a tool, type a question, evaluate the answer and repeat. It was useful and often impressive, but it was also fragmented as each task started from a blank box.

Moreover, early results varied depending on who was prompting and how the models were trained. Many professionals responded to this inconsistency by toggling between multiple AI tools, each with its own strengths, gaps and security considerations.

For a profession built on precedent, consistency and defensibility, that ad-hoc model can only carry a firm so far. If AI is going to meaningfully assist legal practice, it has to support the professional’s holistic workflow, not interrupt it.

From Point Tools to Agentic Processes

The next phase in the evolution of legal AI for Canada is now upon us. The concept is to make available to legal professionals “agentic” AI systems that are capable of executing guided, multi-step processes that transform how lawyers approach research, document drafting, summarization and analysis, and complex legal tasks. So rather than asking a series of one-off prompts, professionals can run an entire process — with legal rigor built in at each step.

The recent general availability of Lexis+ with Protégé in Canada puts this idea into practice at scale. The platform — which replaces Lexis+ AI^TM as the LexisNexis^® flagship — delivers purpose-built, end-to-end legal AI workflows through a redesigned interface built around a single, conversational prompt box. From that one starting point, legal professionals can access pre-built workflows for litigation, transactional work and everyday legal tasks, such as drafting a motion, generating lease agreements or summarizing interviews.

These workflows are powered by LexisNexis-enhanced and secure general AI models from Anthropic and OpenAI. They are designed to help legal teams complete complex work faster improve consistency across matters and deliver high-quality results at scale, whether the work draws on authoritative LexisNexis Canada content, a firm’s documents or both.

Why Authority Still Decides Everything

Speed matters, but in legal practice, trust determines whether a tool gets used twice. What separates purpose-built legal AI from general-purpose alternatives is what sits underneath it.

Every response in Lexis+ with Protégé is grounded in the comprehensive LexisNexis Canada collection of primary law, exclusive secondary sources and Practical Guidance spanning more than a dozen practice areas. Citations can be validated for status and treatment directly within the research and drafting workflow. For Canadian practitioners, this means that Lexis+ with Protégé can navigate both common law principles and jurisdiction-specific requirements, drawing from the comprehensive LexisNexis repository of Canadian legal content, case law and regulatory materials.

All legal AI tools developed by LexisNexis are created by a team of more than 2,000 technologists, data scientists and subject matter experts, following the RELX Responsible AI Principles, which incorporate human oversight mechanisms and ethical AI development practices. This approach addresses important concerns within the Canadian legal profession about AI reliability and accountability in legal work product.

“Canadian legal professionals are under real pressure to do more with less, and they need tools that actually reflect how legal work gets done,” said Sam Puchala, President and General Manager of LexisNexis Canada. “Lexis+ with Protégé brings together comprehensive legal content and verifiable, citable sources in a secure environment. It is designed specifically for legal practice, not adapted from general-purpose AI, which means teams can work through matters from start to finish and trust that what they are producing is consistent and defensible.”

That last word — defensible — is the one that still matters most in the practice of law. Efficiency gains mean little if the output can’t stand up to scrutiny from a partner, client or trier of fact.

Legal AI for Canada

The arrival of this new phase of legal AI in Canada signals something bigger than a new product milestone, it suggests the profession is moving past the experimentation stage and into an era where AI is woven into the fabric of legal work … structured, secure and grounded in authority.

For Canadian legal teams weighing their next move, the opportunity isn’t just to work faster; it’s to work with greater consistency and confidence, from start to finish.
