Garfinkle Biderman LLP is a Toronto business law firm founded in 1948. It's based at 1 Adelaide Street East, Suite 801, at the southeast corner of Yonge and Adelaide in downtown Toronto, with an office connected to the King subway station and a short walk from Union Station. The firm organizes its barristers and solicitors across corporate and commercial law, mergers and acquisitions, securities and capital markets, real estate, franchise and licensing, employment, and litigation, among other business practice areas. It describes its clients as ranging from entrepreneurial start-ups and industry associations to large corporations and financial institutions.

The firm's real estate group has advised lenders, developers, and property owners for more than 70 years, on acquisition and construction financing, commercial leasing, and condominium and new home development.

Its litigation team appears at all levels of court in Ontario and before many tribunals, on matters that range from shareholder and franchise disputes to mortgage enforcement and professional negligence claims.

The neighbourhood

Garfinkle Biderman's office sits at 1 Adelaide Street East, on the southeast corner of Yonge and Adelaide in downtown Toronto.

That transit link suits a firm whose corporate, securities, and real estate work draws clients from across the country, not just the surrounding blocks.
