About Henderson & Co.

Henderson & Co. is an entertainment, media, and trademark law firm in Toronto, founded in 2000 by Kate Henderson. Before starting the practice, Henderson worked as an associate in the intellectual property department at Gowling, Lafleur, Henderson, handling complex intellectual property licensing arrangements and trademark prosecutions after being called to the Ontario bar in 1996 and earning an LLB from the University of British Columbia in 1994. Henderson left Gowlings in 2000, attended the Ontario College of Art and Design, and opened a solo practice focused on the creative industries.

The firm advises musicians, filmmakers, advertising agencies, and small to medium-sized businesses on trademark registration along with music, film, television, and advertising contracts. Associate Devin Fulop, also a registered trademark agent, completed articles at the firm and was called to the Ontario bar in 2015 after undergraduate studies at the University of Victoria and a law degree at Western Law. The firm's client list has included the company that manages the literary estate of Anne of Green Gables author L.M. Montgomery, several musicians and producers, and Toronto hospitality group INK Entertainment.

The neighbourhood

Henderson & Co.'s office is on Vine Avenue in Toronto's High Park North neighbourhood, an area that took shape after the old Keele estate was subdivided into house lots in 1882 to house workers and residents connected to the nearby Junction's commercial district. Vine Avenue sits among the semi-detached houses built in the early twentieth century that give the neighbourhood its Victorian, Edwardian, and Tudor style character, a residential setting a fair distance from Toronto's downtown legal towers. Three subway stations on the Bloor-Danforth line, Dundas West, Keele, and High Park, serve the surrounding area.
