About Walker Sorensen LLP

Walker Sorensen LLP is a small business law firm in Toronto focused on insurance and reinsurance, corporate governance, and law firm professional liability risk management. It was founded in April 2007 by John L. Walker and Sean G. Sorensen; Sorensen had previously been a partner in McCarthy Tetrault LLP's Business Law Group. The firm has stayed small by design, with four partners, an associate, a law clerk, and an executive assistant working from an office on Bloor Street East. From there it advises private corporations, insurers, reinsurers, banks, and professional associations across Canada and abroad.

The firm's insurance and reinsurance practice covers incorporating and licensing new insurers, registering foreign insurer branches, drafting and negotiating reinsurance treaties and commutation agreements, and advising banks on the insurance business rules under the Bank Act. It also runs a niche practice auditing law firms' own professional liability risk, drafting risk management policies and offering online assessment surveys and courses for other firms and insurers. Several of its lawyers have been repeatedly recognized in the Canadian Legal Lexpert Directory and ranked in Chambers Canada for insurance work.
