About Natalie S. Rizkalla-Kamel

Natalie S. Rizkalla-Kamel helps businesses secure, defend and enforce their trademark rights, in Canada and around the world. A Toronto partner in Gowling WLG's Intellectual Property Group and a registered trademark agent, Rizkalla-Kamel concentrates on managing global trademark portfolios, trademark prosecution, IP enforcement and corporate IP strategy. The client list runs from startups to multinationals, in fields as different as cosmetics, pharmaceuticals, retail and cannabis. On deals, the work extends to the IP side of mergers and acquisitions.

Cannabis has been a particular focus ever since recreational use became legal in Canada in 2018. Rizkalla-Kamel helps Canadian cannabis companies plan how to build their brands and has represented them in trademark disputes over those brands, both in court and outside it. That experience has taken the partner onto panels in Montreal and Mexico City, and World Trademark Review sought Rizkalla-Kamel out for an interview on cannabis branding and trends in Canada.

Engineering came before law. Rizkalla-Kamel earned civil engineering degrees at the University of Manitoba and at Queen's University, where the master's was funded by an NSERC scholarship, and worked as a structural engineer before joining the firm. The PEng licence in Ontario is still held today. Called to the Ontario bar in 2006 after a JD at the University of British Columbia, Rizkalla-Kamel later headed the firm's Toronto IP department and sat on its Toronto Management Committee.
