About Radnoff Haworth LLP

Radnoff Haworth LLP is a small Toronto law firm on University Avenue that handles tax disputes, employment law, shareholder and franchise conflicts, and reviews of lawyers' billing. Jeffrey Radnoff started the practice as Radnoff Law Offices and has worked in tax matters for more than 20 years. Charles Haworth articled at the firm in 2015, was called to the Bar of Ontario in 2016, and later became a partner, when the firm took its current name. In 2019, while it still operated as Radnoff Law Offices, Canadian Lawyer Magazine named it one of Canada's Top 10 Boutique Tax Law firms.

Radnoff has more than 25 years of litigation experience, including cases before the Ontario Court of Appeal, the Federal Court of Appeal, and the Tax Court of Canada, where the firm has appealed a range of tax assessments. Radnoff also served on the Ontario Bar Association's Council, held terms as chair, vice chair, and secretary of its Civil Litigation Section, and taught the province's Bar Admission Course. Haworth qualified as a barrister in England and Wales in 2013 and earned a Master of Laws degree the year after, before joining the Ontario bar. In employment and shareholder or franchise disputes, the firm represents clients on either side, whether an employer or employee, a franchisor or franchisee.
