Canadian legal professionals are under growing pressure to do more with less, handling increasingly complex matters across multiple jurisdictions, meeting rising client expectations, and managing larger volumes of documentation. Finding an AI solution they can trust with high-stakes legal work is essential to their practice. 

CoCounsel Legal Canada was built for that purpose. 

Introducing CoCounsel Legal Canada 

​​CoCounsel Legal Canada is the only comprehensive AI solution for Canadian legal professionals that combines advanced AI capabilities with the authoritative depth of Westlaw content and the applied guidance of Practical Law, in a single integrated solution built for the way legal professionals work. Where other tools address parts of the legal workflow, CoCounsel Legal Canada is built to handle the full span of it. The result is faster, more confident legal work across research, document analysis, drafting, and organizational know-how.​ 

Here is what that looks like in practice: 

• Research that produces work product. Canadian legal professionals have had access to Deep Research on Westlaw Advantage, grounded in authoritative Westlaw content. CoCounsel Legal Canada takes that further. Through CoCounsel Legal Canada, Westlaw and Practical Law now are combined into a single query and response, surfacing answers for the user from both premium content sources. Westlaw’s legal authority and Practical Law’s applied, expert-created guidance surfaces the law and how to use it, moving from question to strategy to execution in a single workflow.   
• Document analysis at genuine scale. Tabular analysis allows legal teams to work through large volumes of documents in ways that weren’t previously feasible without significant resource commitment. Whether the task is due diligence, disclosure review, compliance assessment, or privilege review, CoCounsel Legal Canada surfaces risks across multiple issues simultaneously, links findings to source documents, and generates draft reports. The results are designed to be reviewed and challenged, because that is how legal work functions. 
• Drafting within existing environments. Enhanced drafting within Microsoft Word allows lawyers to produce high-quality first drafts without leaving the tools they already use, drawing on Practical Law content and their own organizational precedents. The goal is not to replace professional judgment. It is to compress the distance between instruction and a verified, defensible final draft. 
• An expert library. Access expert-created prompts and create custom prompts designed to help legal professionals get started faster and work with greater confidence. The library accelerates AI adoption across an organization while codifying best practices, so teams can build capability consistently rather than starting from scratch on every matter. 

​​​CoCounsel Legal Canada integrates with Microsoft 365, leading document management systems, and HighQ, working within the infrastructure Canadian legal practices have already built rather than requiring parallel workflows or new platforms. ​​ 

​​​Because the work of legal professionals doesn’t stand still, neither does CoCounsel Legal Canada. Looking further ahead, Thomson Reuters will continue to build on its foundation, introducing additional agentic drafting capabilities, ways to enable more efficient lawyer verification of outputs, and next-gen capabilities that respond to a plain-language question by forming a theory and executing a plan at the level of a senior associate, drawing on Westlaw, Practical Law, and firm content throughout the workflow.​​ 

“Lawyers don’t want to just operate software, and that’s not what great AI should do. CoCounsel keeps them in the analytical mindset they were trained for: going back and forth, challenging answers, and steering the work. With sourcing directly from Westlaw and Practical Law, they’re not wasting time second-guessing the results. We’re seeing adoption from associates to partners across every practice area. When it spreads that quickly, the experience just works.”
— Andrew M. Medeiros, Managing Director of Innovation, Troutman Pepper Locke LLP 

CoCounsel Legal Canada is built to the standard legal work demands 

Powerful capabilities matter only if professionals can trust the results they produce. Legal work carries liability. Outputs inform advice. Advice affects outcomes. In that environment, “almost right” is not a workable standard. 

​​Thomson Reuters uses the term Fiduciary-Grade AI™ to describe what AI must be in order to function reliably in high-stakes professional environments, and it is the architectural foundation of CoCounsel Legal Canada. ​ 

​​​​It means outputs grounded in authoritative, curated content, not the open internet. It means privacy and security built into the system’s architecture, not layered on as policy. It means transparent, traceable reasoning that a lawyer, client, court, or regulator can examine and challenge. And it means the continuous involvement of credentialed subject-matter experts. Thomson Reuters employs thousands of lawyer editors whose work is not incidental to the product’s reliability. It is the product’s reliability.​​​ 

“The reality is from what we’re seeing out there, it’s not a fair fight right now. CoCounsel nailed it in terms of the user interface and making it easy for even non-technical people like me to use.”
— Ian Hull, Co-Founding Partner, Hull & Hull LLP 

The practices built today define the profession tomorrow 

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. Getting there successfully means choosing AI built for professional work, not just productivity, and investing in the workflow integration that turns capability into a competitive advantage. 

Canada has something valuable to contribute to the global conversation about what responsible AI adoption in regulated professions should look like. A professional culture built on precision, accountability, and trust is not an obstacle to AI adoption. It is the foundation for doing it right. The legal profession has always been defined by the trust placed in it. The practices that move deliberately now will be the ones defining what excellent Canadian legal work looks like in the years ahead. 

CoCounsel Legal Canada is available now, and we’re proud to bring it to the professionals who set that standard.
