Meet Peter W. Kryworuk

Plaintiff Class Actions Lawyer

"I was a senior counsel in one of the longest class action trials in Canadian history. It's a unique challenge and is different from general litigation. Class action law is constantly evolving. Each case requires us to integrate and balance our strategic, intellectual and procedural skills in a different way."
