David Ewart, ISO (18 February 1841 â 6 June 1921) was a Canadian architect who served as Chief Dominion Architect from 1896 to 1914.
As chief government architect he was responsible for many of the federal buildings constructed in this period. He broke with the Neo-Gothic style adopted by his predecessors Thomas Seaton Scott and Thomas Fuller; rather, he embraced the Baronial style exemplified in several important buildings.
In 1903, Ewart was awarded the Imperial Service Order.
Ewart was married to Jeanne Marie Doyen until her death in 1885. He was then married to Annie Sigsworth Simpson from 1887 to his death in 1921.
His son John Albert Ewart was an acclaimed Ottawa architect.
As federal architect he oversaw the design and construction of several buildings at the Central Experimental Farm including the Dominion Observatory, Carling Avenue in 1902; Chief Astronomer's Residence, 1909; and the Geodetic Survey Building, 1914. He also oversaw the design and construction of numerous post offices (such as the Humboldt Post Office). He oversaw the design and construction of numerous armouries across Canada.
