About Advocan Law LLP

Advocan Law LLP is a small firm based in Toronto, with an office at 157 Adelaide Street West. David Latner started the firm in November 2016 after a career as in house counsel, and it has since grown to two lawyers. The firm concentrates on three areas: technology, financings, and commercial litigation. It advises entrepreneurs, investors, and technology companies on matters like intellectual property ownership, client and vendor contracts, and venture financings, and it represents clients in court, before tribunals, and in mediation. The firm describes its client base as extending well beyond Toronto, including companies and investors outside Canada.

Before co-founding Advocan, David Latner spent about a decade as general counsel to BlueCat Networks, an enterprise software company, and was earlier general counsel and partner at XDL Capital, a Toronto venture capital firm. Latner also mentors founders through the University of Toronto's Health Innovation Hub (H2i). The firm's other lawyer, Gabriel Latner, holds an LLM and is admitted to practice in both Ontario and New York after training in the UK and the US. Gabriel Latner's work combines transactional and strategic advice with courtroom advocacy, including acting for a defendant in Ang v Second Closet Incorporated, a commercial dispute valued at 16.6 million dollars that was covered by Canadian Lawyer magazine.
