About Ballantyne Family Law

Ballantyne Family Law is a Toronto firm that practices family law exclusively, working out of an office at 10 Alcorn Avenue in the Summerhill area of midtown Toronto. Karen Ballantyne leads the firm and has practiced family law since being called to the Ontario Bar in 2003, after graduating from Osgoode Hall Law School in 2002 and articling at a Bay Street firm. The team of three lawyers handles cohabitation agreements, marriage contracts, separation agreements, parenting issues, support claims and property division.

The firm is trained in the collaborative method and generally steers clients toward negotiation, mediation or arbitration where that fits, while litigating in the Ontario Court of Justice, the Superior Court of Justice and the Court of Appeal when a matter needs to go to court. The team includes Nadine Waldman, called to the bar in 2008, who can advise clients in French and English, and Lily Chapnik, called in 2022, who trained as a social worker before becoming a lawyer. Law clerk Bonnie Frieday, who has worked as a court reporter and legal researcher, handles financial statements and simple divorce applications and liaises with courts and clients.

The neighbourhood

The firm's office at 10 Alcorn Avenue sits in a building constructed in the 1930s that was home to hardware wholesalers, including Walker and Sons and White's Hardware, between 1925 and 1950, before it was restored into office space in 1991. It's a low rise brick and stucco building with a landscaped interior courtyard, in the Summerhill area of midtown Toronto just west of Yonge Street.

The area mixes restaurants and small shops with a residential feel and sits a short walk from Summerhill subway station. For a firm whose lawyers appear in courts across southern Ontario, an office that's easy for clients to reach by transit, and easy to find among the neighbourhood's older commercial buildings, is a practical fit.
