About Perez Procope Leinveer LLP (PBP Lawyers)
Perez Procope Leinveer LLP, known as PBP Lawyers, is a Toronto firm focused on health law, estate advocacy, and civil rights. The firm was founded in 2016 and works out of an office at 55 University Avenue, representing clients before administrative tribunals and all levels of court in Ontario. Lisa Leinveer joined the firm as a partner in January 2025, and the firm's name was updated to reflect the new partnership.
The founding partners bring long backgrounds in capacity and mental health law. Mercedes Perez was called to the Ontario bar in 2003, co-instructs a Law and Psychiatry course at Osgoode Hall Law School, and has served as amicus curiae in Charter cases, including a 2023 Ontario Superior Court ruling on encampment evictions in the Waterloo Region. Alexander Procope, called to the bar in 2007, focuses on capacity, guardianship, and estate disputes and received the Ontario Bar Association's Hoffstein Book Prize in 2022 for contributions to wills, trusts, and estates law. The firm describes its retainer terms as fair and transparent, without hidden fees.

Who handles what
The neighbourhood
The firm's office is on University Avenue in downtown Toronto, in the stretch of the street known locally as Hospital Row for its concentration of teaching hospitals, including Toronto General, Mount Sinai, and the Hospital for Sick Children. The same corridor runs past the Toronto Courthouse and Osgoode Hall and sits within the MaRS Discovery District. For a firm built around health law, capacity work, and litigation, that mix of hospitals and courts is close to home.
The office is a short walk from St. Andrew and Union subway stations and the King streetcar line. Meetings run by appointment, and the firm will accommodate evening or weekend appointments on request.
