    WeirFoulds LLP has established itself as one of Canada’s premier regional law firms, and has provided strategic, cost-effective and innovative legal advice to clients since 1860. WeirFoulds has thrived by becoming a true partner to clients, ensuring that legal advice addresses their priorities. The firm is repeatedly ranked as one of the Canadian Lawyer 'Top 10 Ontario Regional Firms', and is regularly listed in Novae Res Urbis' 'Top 10 Development Law Firms in the GTA'. These listings are testaments to the firm’s client-service focus. With roots firmly planted in the Greater Toronto Area, and a client base that is large and diverse, the firm offers responsive and effective client service in four broad areas of practice: corporate, litigation, property and government.
