About Kawaguchi Krajden LLP

Kawaguchi Krajden LLP, known as K2LLP, is a Toronto civil litigation firm on Castlefield Avenue. Heather L. Kawaguchi and Ari Krajden founded the practice after each spent years litigating insurance and personal injury claims, and the firm has since grown to seven lawyers. It represents individuals, businesses, and insurers in insurance litigation, personal injury, and medical malpractice matters, appearing before the Superior Court of Justice, the License Appeal Tribunal, and Small Claims Court.

Krajden holds the Law Society of Ontario's Certified Specialist designation in Civil Litigation, a credential the Law Society reports is held by less than 1% of lawyers in the province. Krajden and Kawaguchi both offer mediation services, and Kawaguchi also acts as a private arbitrator in priority and loss transfer disputes. Several of the firm's lawyers have been named to Best Lawyers in Canada or Best Lawyers: Ones to Watch in Canada for personal injury and insurance law, and the firm's associates regularly write and speak on developments in Ontario's accident benefits system, including the Statutory Accident Benefits Schedule.

The neighbourhood

K2LLP's office sits on Castlefield Avenue, the main street of what locals call Toronto's design district, known for its concentration of furniture and interior design showrooms in converted industrial buildings. It's a working commercial strip rather than a courthouse row, which suits a litigation practice whose lawyers spend most of their court time downtown at the Superior Court of Justice.
