Miller Thomson office in Markham

Miller Thomson LLP is a full-service national law firm established in Toronto, Ontario, Canada in 1957.[1] The firm provides a complete range of business law, advocacy, and personal legal services to Canadian and international corporations, entrepreneurs, institutions, governments and not-for-profits.

Miller Thomson is currently Canada's seventh largest law firm[2] with over 550 lawyers and 12 offices located in Vancouver, Calgary, Edmonton, Saskatoon, Regina, London, Kitchener-Waterloo, Guelph, Toronto, Vaughan, Markham, and Montréal.[3]

Notable firm alumni include former Canadian Prime Minister, The Right Honourable John Turner, P.C., C.C., Q.C.[4] (retired Partner),[5] Supreme Court of Canada Justice Russell Brown, who was associate counsel to the firm prior to his appointment, and former Alberta Minister of Justice & Attorney General Jonathan Denis.[6]


Miller Thomson was founded on Canada's 90th birthday - July 1, 1957 - by six lawyers who decided to leave a large firm and establish their own firm which was then known as Miller, Thomson, Hicks & Sedgewick. The original partners were J. A. F. Miller, Q.C., J. H. Thomson, Q.C., R. V. Hicks, Q.C., R. M. Sedgewick, C. W. Lewis, and J. Wilfred Healy.

Today, their namesake has grown and evolved into one of the largest law firms in Canada. Through a series of strategic mergers, the firm has expanded to 12 offices and over 550 lawyers.[7]

Innovative & Leading Law Firm

Open Plan Concept Offices

Miller Thomson's Vancouver office relocated to a hybrid open plan concept office space in 2016,[14] located above the Nordstrom department store in the redeveloped Pacific Centre building.

Miller Thomson sought to have space reflect what the firm stands for and what sets it apart from the competition. "We see ourselves as part of the community and we take energy from collaborating with clients and from their resulting success. So our office had to cater to our clients," said Mike Walker,  Office Managing Partner for Vancouver at the time of the move. "We also wanted to be more prominent in the legal market itself with space that would get the competition talking about us and pique the interest of great lawyers at other firms with a similar perspective, energy and entrepreneurial spirit."[15]

The firm's newest location in Vaughan, which opened in the summer of 2017, has followed with a similar open-concept workspace.[16]
