History

Miller Thomson was founded on Canada’s 90th birthday – July 1, 1957 – by six lawyers who decided to leave an established large firm and embark on their own adventure. Almost sixty years later, their namesake has grown and evolved into one of the largest law firms in Canada.  Through a series of mergers with other well-respected firms, Miller Thomson has expanded to 12 offices and close to 550 lawyers.  Today, we cover Canada better than any other national business law firm, with deep roots in the communities where we work and live.
