Toronto History

Miller Thomson's Toronto office was founded on July 2, 1957. From four founding partners at 55 Yonge Street, the office complement climbed to about 30 lawyers by the mid-1970s.

Despite the economic recession of the following decade, the Toronto office began positioning itself for the future — relocating in August 1981 to larger premises in the new south tower of the landmark Toronto Eaton Centre. By 2004, with a corporate client base that continued to flourish and close to 200 lawyers and staff, the office began planning a move in February 2006 to its current location, the prestigious Scotia Plaza.

Today, the Toronto and nearby Markham offices include over 170 partners, associate counsel and associates.


Miller, Thomson, Hicks & Sedgewick was located at 55 Yonge Street. Starting out as specialists in corporate, tax, estates and labour, the Toronto firm was small but vibrant.


Elaine McCallum was the firm's first female lawyer and first female partner. Jane Roffey was the firm's first hired female lawyer. Today almost 40% of all lawyers at the office are women.


Known then as Miller, Thomson, Sedgewick, Lewis & Healy, the firm expanded its footprint by opening an office in Markham.


Common usage and trends of the day prompted the firm to change its name to Miller Thomson.


Hiring former Canadian Prime Minister John Turner lifted the firm to a new level.


Six of the Toronto partners have been elevated to the Bench. Four of them are still active: Gans, Sproat, Daley, Lauwers. Two sit as Supernumerary Judges — Mogan and Sheppard.
