About Greybox Legal LLP
Greybox Legal LLP is a small law firm based in Toronto, Ontario, with its office on Yonge Street in the North York City Centre business district. It was co-founded by partners Eli Leibowitz and Jason Rosen, who describe the firm's approach as working at the intersection of business, tax, and private capital, or in the firm's own words, "strategy, structure, and legacy."
The firm's practice spans four areas: corporate structuring, tax planning, mergers and acquisitions, and private client matters, including wills, estates, and wealth preservation across generations. Its clients are described as founders, owner-operators, family enterprises, private investors, and high-net-worth individuals who need precise, discreet advice on transactions and succession planning.
Greybox Legal is a small team. Alongside its two founding partners, the firm has an associate who focuses on wills and estates, plus corporate, tax, and estate-planning law clerks and other support staff who round out the practice.
