Miller Thomson’s History

Formed in 1957 as Miller, Thomson, Hicks & Sedgewick, it is now one of Canada’s leading business law firms.

Starting with just six Toronto lawyers, Miller Thomson’s practice underwent two dramatic periods of growth. The first was through the 1960s, and again between 1992-2007 through a series of mergers with well-respected firms and practices that have helped build a strong national presence for Miller Thomson.

Through strategic growth, the firm has added enhanced capabilities, depth and resources to serve its steadily expanding domestic and international client base.

With 11 offices country-wide, Miller Thomson can cover Canada better than any other firm.
