About Alexander Stack Professional Corporation
Alexander Stack Professional Corporation is a solo intellectual property and commercial law practice in Toronto, run by lawyer Alexander Stack. The firm handles patents, trademarks, trade secrets, industrial designs, copyrights, and commercial agreements, with particular depth in the technology and pharmaceutical sectors. It also acts as local representative in Canada for foreign law firms, companies, and individuals pursuing patent, trademark, and other intellectual property protection here. Clients come from Toronto, Hamilton, Kitchener, Waterloo, and Ottawa, as well as further afield across Canada and globally.
Before founding the firm, Stack practiced at one of Canada's largest law firms, then at a small firm focused on litigation and regulated-industry advice, and later worked as in-house counsel for a pharmaceutical company. Stack is called to the bar in Ontario and is a registered patent and trademark agent in both Canada and the United States, with an educational background in chemical engineering and chemistry and a master's degree in nonlinear modelling and control in the chemical industry. Stack also teaches intellectual property law and strategy in the University of Toronto Faculty of Law's Global Professional LLM program, teaches intellectual property and business law courses at Ryerson University's Ted Rogers School of Management and the Chang School, and has authored or co-authored two books on intellectual property law.

Good to know
Wheelchair accessible
By appointmentWho handles what
The neighbourhood
The firm's office is on Pleasant Boulevard in Toronto, near St. Clair station. St. Clair subway station has a secondary, wheelchair-accessible entrance at concourse level on Pleasant Boulevard itself, so clients arriving by TTC can reach the building without a detour onto St. Clair Avenue.
Because the firm's clients are spread across Toronto, Hamilton, Kitchener, Waterloo, and Ottawa, and further afield across Canada and internationally, the practice works less like a neighbourhood storefront and more like a base for a portable technology and pharmaceutical intellectual property practice. The midtown Toronto address keeps it close to transit and to the downtown core for the clients who do come in person.
