He represented Shelburne County in the Nova Scotia House of Assembly from 1906 to 1925 as a Liberal member. Irwin was the 17th Lieutenant Governor of Nova Scotia from 1937 to 1940.

Jared Irwin served twice as elected Governor of Georgia (1796–1798) and (1806–1809). He first was elected to office as a reformer based on public outrage about the Yazoo land scandal. He signed a bill that nullified the Yazoo Act, which had authorized the land sales. Challenges to land claims purchased under the former act led to the United States Supreme Court's hearing the case Fletcher v. Peck (1810). In a landmark decision, the Court upheld the land contracts, and ruled that the state law was unconstitutional in trying to nullify valid contracts.
