Adamson Associates

Adamson Associates is a Toronto-based architectural firm founded in 1934.

Gordon Sinclair Adamson (1904-1986) started the firm in 1934 after working for a number of other architects (F. Hilton Wilkes and Edwin Kay), as well as noted Henry Sproatt and Ernest Ross Rolph. He worked briefly with Earle Morgan, but most of his practice was on his own or with associates. His practice was mainly residential, commercial or industrial clients in Ontario.

Adamson's firm employed another Toronto architect John B. Parkin and Adamson retired and left the firm in 1971.

The firm operated as G.S. Adamson, briefly as Adamson and Morgan in the 1940s, then as Gordon S. Adamson & Associates and renamed Adamson Associates since.

Adamson entered into the contest to design the new Toronto City Hall in 1958.

Since his departure the firm has been involved in other projects in Canada and overseas:
