About Piller & Ross

Piller & Ross is a small Toronto law firm based in Law Chambers, an office arrangement built specifically for independent lawyers. Rather than running a stand-alone office, the firm leases space at 181 University Avenue and shares administrative support and infrastructure with other independent practices in the same building. Law Chambers has a second Toronto location at 393 University Avenue, and together the two buildings house lawyers across a wide range of practice areas, each running a separate practice.

Leslie A. Piller, a lawyer at the firm, holds a B.A. from McMaster University in Hamilton and an LL.B. from Queen's University in Kingston. Piller was called to the Ontario bar in 1973 and has over 40 years of experience in family law and wills and estates law, practising from the University Avenue office.

The neighbourhood

The firm's office is in DBRS Tower at 181 University Avenue, at the corner of Adelaide Street West, in Toronto's financial district. St. Andrew subway station is close by, and the building connects directly into the PATH, the underground network linking downtown offices to shops and restaurants across the core.

Piller & Ross doesn't run a typical stand-alone law office. It operates out of Law Chambers, where independent lawyers lease private offices in the same building and share administrative support and infrastructure rather than merging into a single firm.
