On June 1, Thomson Reuters launched CoCounsel Legal Canada — described as the only comprehensive AI solution for Canadian legal professionals, combining Westlaw Advantage content and Practical Law applied guidance in a single query and response interface. The platform covers research, document analysis (including tabular analysis for due diligence, disclosure, and privilege review), and drafting within Microsoft Word, drawing on both Practical Law content and a firm's own organisational precedents. A prompt library codifies best practices to enable consistent capability building across an organisation — a direct KM operating model feature. In parallel (May 12), Thomson Reuters confirmed it is integrating Anthropic's Claude into the CoCounsel Legal product, expanding model flexibility. Integrations include Microsoft 365, leading DMS platforms, and HighQ.
