About Paterson MacDougall LLP
Paterson MacDougall LLP is a Toronto law firm that traces its roots to 1953, when Alastair Paterson, a partner at the London aviation law firm Beaumont and Sons, emigrated to Toronto and began practising law. Other lawyers joined the practice over the following years, and in 1977 it took the name Paterson, MacDougall, known today as PM Law.
That connection shaped the firm's early focus. PM Law says it's provided aviation legal services for more than 50 years, representing airlines and their insurers in aviation accident, cargo, and product liability matters across Canada. Its insurance and reinsurance practice, which the firm describes as having over 45 years of experience, advises insurers on coverage questions and defends insured parties. Since then PM Law has built out practices in municipal and government liability, professional and product liability, transportation, media and defamation, and wills and estates. Its lawyers have written on aviation and municipal liability law, including a chapter on Aviation and Space Law in Halsbury's Laws of Canada and a book, The Law of Municipal Liability in Canada.
