Our History
The history of Aird & Berlis LLP dates back to 1919 when its predecessor opened its doors for business. In 1974, the firms of Zimmerman, Grant, Hugo, Paddon, Worley & Bennett merged with Edison, Aird & Berlis to form Aird, Zimmerman & Berlis. The name was changed to Aird & Berlis circa 1978, and the LLP suffix was added later.

John Aird was appointed to the Senate of Canada in the 1960s and served as Ontario's 23rd lieutenant governor from 1980 to 1985. Doug Berlis was the gold medalist in his graduating year at law school. Together, they built a firm of people-focused, bright, technical lawyers and created an atmosphere of entrepreneurship and teamwork. This atmosphere continues to drive the firm's success today and into tomorrow.
