About Grundy, Cass & Campbell Professional Corporation
Cass and Campbell is a small business law, litigation, and estates practice in midtown Toronto, with an office in the Yonge Eglinton Centre at Yonge and Eglinton. Steve Cass started in 1982 after a first law degree from the University of Western Ontario and a graduate degree from the University of Cambridge, and now focuses on corporate and commercial law, wealth management, estates, and succession planning for business owners and their families. John Campbell started in 1980, also with a law degree from Western Ontario, and practised at WeirFoulds LLP from 1980 to 2011 before continuing a commercial litigation practice at Cass and Campbell.
The firm's business law work centres on closely-held and family businesses: the acquisition and sale of non-public companies, shareholder and partnership agreements, and succession planning that can touch on wills, trusts, marriage contracts, and estate freezes. On the litigation side, the firm handles breach of contract, wrongful dismissal, professional negligence, insurance coverage, and shareholder oppression disputes, and describes much of its work as coming through referrals from other lawyers and national or specialty firms in fields like tax, intellectual property, and family law.

Who handles what
The neighbourhood
The firm's office is in the Yonge Eglinton Centre, a two tower, retail-anchored development at the northwest corner of Yonge Street and Eglinton Avenue in midtown Toronto. The 2300 Yonge Street tower opened in 1974, and a 2016 renovation added seven floors along with a new glass curtain wall and a rooftop patio. The complex connects by a concourse-level underground tunnel to Eglinton subway station. Since much of the firm's work comes through referrals from other lawyers, clients and referring counsel can reach the office through the connected concourse without going outside.
