David Wark, (February 19, 1804 – August 20, 1905) was an Irish-born Canadian Senator who served nearly 38 years in office.
He represented Kent County in the Legislative Assembly of New Brunswick from 1843 to 1850. In 1847, he introduced a resolution calling for free trade among the British North American colonies and was, therefore, among the first to seek the closer relations among the colonies that eventually led, 20 years later, to Confederation.
Wark was named to the Legislative Council in 1850 and served until Confederation. He served in the province's Executive Council as a minister without portfolio from 1858 to 1862 and as Receiver General from 1866 to 1867. His father was a farmer near Derry and David Wark was born there on February 19, 1804. By 1836, he had saved enough money to buy his own general store and later, he began a successful, 40-year career in the lumber business.
