Thomson Reuters has launched CoCounsel Legal Canada, bringing its AI-powered legal assistant to Canadian legal professionals.
Announced today in a blog post by Rinaldo Huriptyo, Head of Canada at Thomson Reuters, CoCounsel Legal Canada is described as a comprehensive AI solution built for Canadian legal practice, combining advanced AI capabilities with the legal authority of Westlaw and the applied guidance of Practical Law.
The launch comes as Canadian lawyers face rising pressure to manage increasingly complex matters, larger volumes of documentation, multi-jurisdictional work, and growing client expectations.
“Finding an AI solution they can trust with high-stakes legal work is essential to their practice,” Huriptyo wrote.
CoCounsel Legal Canada is designed to support legal professionals across research, document analysis, drafting, and organizational know-how. According to Thomson Reuters, the platform brings Westlaw and Practical Law together into a single query-and-response experience, allowing users to surface both legal authority and practical guidance within one workflow.
The company said the result is intended to help legal professionals move from legal question to strategy to execution more efficiently.
Beyond research, CoCounsel Legal Canada includes document analysis capabilities for tasks such as due diligence, disclosure review, compliance assessment, and privilege review. Thomson Reuters said the platform can surface risks across multiple issues, link findings to source documents, and generate draft reports designed to be reviewed and challenged by legal professionals.
The platform also supports enhanced drafting in Microsoft Word, allowing lawyers to create first drafts without leaving the tools they already use. The drafting experience can draw on Practical Law content and an organization’s own precedents, with the goal of helping lawyers move more quickly from instruction to a verified final draft.
CoCounsel Legal Canada also includes an expert library of prompts and the ability to create custom prompts, aimed at helping legal teams accelerate adoption and standardize best practices across an organization.
The platform integrates with Microsoft 365, leading document management systems, and HighQ, allowing it to fit into existing legal technology infrastructure rather than requiring firms to build parallel workflows.
Thomson Reuters is positioning the Canadian launch around what it calls Fiduciary-Grade AI, a term the company uses to describe AI designed for high-stakes professional environments. Huriptyo wrote that this means outputs grounded in authoritative, curated content rather than the open internet, with privacy, security, transparency, traceability, and expert oversight built into the system.
The company also signalled that more capabilities are coming, including additional agentic drafting features, more efficient lawyer verification of outputs, and next-generation tools that can respond to plain-language questions by forming a theory and executing a plan using Westlaw, Practical Law, and firm content.
“The decisions being made now—the tools adopted, the workflows built, the institutional knowledge developed around how to deploy AI effectively—are the foundations of what Canadian legal practice looks like on the other side of this transition,” Huriptyo wrote.
The launch of CoCounsel Legal Canada marks another step in the legal industry’s shift from AI experimentation toward workflow-integrated tools built for professional practice.
For Canadian firms and legal departments, Thomson Reuters is betting that the next phase of legal AI will be defined not only by productivity gains, but by trust, verification, and integration with the sources and systems lawyers already rely on.
