About Frenkel Tobin LLP

Clients rate this firm highly on Google.

Frenkel Tobin LLP is a Toronto law firm that practises family law exclusively. David Frenkel, called to the Ontario bar in 2008, and David Tobin, called in 2014, are the firm's name partners. They lead a team of five lawyers working from an office on Adelaide Street West in the city's downtown core. The firm handles parenting arrangements and custody, child and spousal support, division of property, marriage contracts and cohabitation agreements, and separation agreements, and it represents clients across Ontario along with some national and international matters.

David Frenkel and David Tobin edit the Ontario Family Law Monthly, a publication the firm has produced since at least 2023 with contributions from several authors on current family law topics. Frenkel's writing on separation date principles and psychological testing has appeared in the Canadian Family Law Quarterly, and portions of that research were referenced in House of Commons debate on federal family law reform. The firm describes itself as an LGBTQ+ safe space, and one of its lawyers is fluent in Mandarin.

The neighbourhood

Frenkel Tobin's office sits in the Commodore Building at 317 Adelaide Street West, a ten storey structure built in 1929 by architect Benjamin Brown. The building originally served as a warehouse and now sits within the King Spadina Heritage Conservation District, one of the city's designated heritage areas. The block mixes converted industrial buildings with newer office towers a short walk from Toronto's financial district, a setting suited to a firm whose clients come from across Ontario and beyond rather than a single local neighbourhood.
