Bay Street power broker and political fundraiser Ralph Lean has left the firm of Heenan Blaikie after learning it was contemplating chopping the headcount in its Toronto office by half. Mr. Lean has joined the Toronto office of Gowling Lafleur Henderson LLP as counsel just eight months into his two-year contract with Heenan Blaikie. What happened? Apparently about 30 partners have left Heenan Blaikie in recent weeks after a drop in revenue has led to less pay. The cause of this decline wasn’t specified. The firm has announced it will embark on a “major restructuring” in the near future. Some speculation suggests a break up of its network of eight offices across the country. The 68-year-old Mr. Lean worked for 23 years with law firm Cassels Brock and Blackwell in Toronto until last year, when he reached that firm’s mandatory retirement age.
