History

The firm's antecedents include practitioners who established firms in Toronto and other Canadian cities in the early 20th century, leading to amalgamations and expansions during the late 20th century and early 21st century. Key developments involved strategic mergers that created a coast-to-coast footprint, aligning with trends set by firms such as Blake, Cassels & Graydon, Osler, Hoskin & Harcourt, and Torys in pursuing national reach. The firm expanded organically and by integrating local firms in provinces including Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, and Quebec, paralleling consolidation patterns seen with peers like Bennett Jones and Fasken. Throughout its history, Miller Thomson cultivated practice groups responsive to sectors prominent in Canadian commerce, such as energy and natural resources connected to Canadian Natural Resources Limited-style enterprises, financial services similar to Royal Bank of Canada and Toronto-Dominion Bank clients, and energy infrastructure tied to projects like pipelines and power generation.
