Clients rate this firm highly on Google.

Posner Craig Stein LLP is a small Toronto firm focused on criminal defence, working out of a single office on Parliament Street. Richard Posner, Alison Craig, and Gabriel Gross-Stein founded the firm in 2022, and its name reflects those three founding partners. All three had built their careers together before that: Posner had managed the firm Lockyer, Campbell, Posner for 17 years, Craig had joined that same firm as an articling student in 2005 and made partner there in 2011, and Gross-Stein had joined in 2013 and made partner in 2019. By the time PCS opened its doors, the founding group already had a long shared history in criminal defence work.

The firm handles criminal charges at every stage, from investigations and bail hearings through trial, sentencing, and appeals. Alongside that, it has built a professional discipline practice representing doctors, nurses, lawyers, accountants, engineers, and other regulated professionals in complaints and discipline proceedings before their licensing colleges.

The neighbourhood

Posner Craig Stein's office is on Parliament Street in Cabbagetown, a downtown Toronto neighbourhood. Cabbagetown holds the largest continuous stretch of preserved Victorian housing in North America, built up mostly in the late 1800s and early 1900s. The name comes from Irish immigrants who settled the area in the 1840s and, according to local history, grew cabbages in their front yards. The neighbourhood declined for much of the twentieth century before its Victorian homes were restored starting in the 1970s, and it's now known for that mix of heritage architecture and small, independent businesses.

The Toronto Necropolis, a cemetery dating to 1850, and Riverdale Park West both sit close to the firm's Parliament Street address.
