The neighbourhood

The firm's Toronto office is located in midtown Toronto. The firm describes Toronto itself as the heartland of Canadian business, home to the Toronto Stock Exchange and the head offices of most major Canadian banks, a framing that fits a practice built around commercial contracts, procurement, and project finance rather than courtroom litigation.

Derman Law also lists offices in Montreal and New York, and connects both cities to its practice rather than treating them as an afterthought. Montreal is home to the International Air Transport Association and the International Civil Aviation Organization, relevant to the firm's aviation work, while the firm describes New York as the legal hub of North America for cross-border transactions.
