Hamilton Duncan Armstrong & Stewart Law Corporation originated in 1959 as the firm of Jensen, Hamilton & Hamilton. Robert Jensen, Howie Hamilton, and Roger Hamilton practised under that name until 1962 when Howie Hamilton moved to Penticton where, in due course, he became a Justice of the Supreme Court of British Columbia. With the departure of Howie Hamilton, the firm became Jensen & Hamilton.

Brian Duncan and Trevor Armstrong joined the firm in 1974 and 1978 respectively and they took over the practice when Robert Jensen became a Judge of the Provincial Court of British Columbia in 1979. They renamed the firm Hamilton, Duncan & Armstrong.

James Stewart joined the firm in 1980 and became a partner in 1983 when the firm became Hamilton, Duncan, Armstrong & Stewart Law Corporation.

From 1993 to 1998 the firm merged its practice with Bull, Housser & Tupper and then resumed practice as Hamilton, Duncan, Armstrong & Stewart Law Corporation when Brent Stickland joined as a partner at the firm's current offices on the 14th floor of the Station Tower, Gateway, in Surrey, British Columbia.

Throughout its history the firm has been dedicated to serving the needs of our clients and the business community.
