This document summarizes a case study on how Canadian law firms are using social media. It finds that adoption has been limited except by the largest firms. Barriers include concerns over privacy and ethics. Through interviews, the document examines one Toronto law firm's social media use and challenges, such as lack of strategy and resources. It reviews best practices from the US and recommends platforms and content approaches. The literature review covers diffusion of innovation and other theories to explain slow adoption rates. Overall, the document finds Canadian law is late to adopt social media, but its use can help with branding, business development and thought leadership if barriers are addressed.
