About Rotenberg Shidlowski Jesin (RSJLAW)

RSJLAW, formally Rotenberg Shidlowski Jesin, is a small criminal defence practice in downtown Toronto. Robert Rotenberg and Alvin Shidlowski founded the firm in 1992 to offer one on one client service, and Jacob Jesin joined as a partner in 2006, giving the firm its current name. The three lawyers practise in association and, together, count more than 70 years of combined courtroom experience. They take on criminal and regulatory matters across the Greater Toronto Area and Southern Ontario, from theft and impaired driving to sexual assault, large scale fraud, and murder.

Each partner brings a different background to the practice. Shidlowski started in corporate and merger and acquisition law at Torkin Manes, then built a criminal practice focused on commercial crime, and continues to advise on business law alongside it. Jesin has developed a niche representing complainants and witnesses in sexual assault and domestic violence matters, and both Jesin and Shidlowski sit as panel lawyers for Ontario's Independent Legal Advice for Survivors of Sexual Assault program. Rotenberg is also the author of five novels and a screenwriter, alongside the criminal law practice.

The neighbourhood

RSJLAW's office sits on King Street East, in Toronto's old St. Lawrence neighbourhood. King Street was one of the first streets laid out in the 1793 town plan of York, and once the St. Lawrence Market opened nearby in 1803 it grew into the main commercial street of early Toronto. The original commercial blocks burned in the Great Fire of 1849 and were rebuilt afterward, and today King Street East is known for its concentration of furniture and design showrooms, a different kind of commercial district than it started as, but one that still trades on the same stretch of road.

It's a fitting setting for a firm built around long standing relationships rather than a high volume practice: a historic, walkable corner of downtown Toronto rather than a tower on Bay Street.
