CCSB Law LLP is a Toronto business law firm whose full name, Cummings Cooper Schusheim Berliner LLP, comes from its founding partners. The firm was founded in 1995 by lawyers who had all previously worked at large downtown Toronto firms and decided to build a smaller, more personal practice where they could get to know clients, their families, and their businesses directly. Today the firm has nine lawyers working from an office on Yonge Street in Toronto, focused on corporate law, commercial real estate, tax law, and wills, trusts, and estate planning for entrepreneurs and privately held and family-owned businesses.
Several of the firm's lawyers bring teaching and cross-border experience to that work. One founding partner has taught corporate taxation at Osgoode Hall Law School and lectured for the Law Society's Bar Admission Course, and one of the firm's real estate partners was called to the bar in Quebec before being called in Ontario. The firm's practice areas include international tax, and the corporate practice handles everything from shareholder agreements to the purchase and sale of businesses, including business expansion both in and out of Canada.
Wheelchair accessible
By appointmentCCSB Law's office is in the Yonge Corporate Centre at 4100 Yonge Street, one of three six storey office buildings on the site built between 1985 and 1989. A pedestrian tunnel connects the complex to the York Mills subway station, so clients meeting with the firm's corporate, tax, and estate planning lawyers can reach the office by transit rather than driving to a downtown tower.
