Pascal Poirier (February 15, 1852 – September 25, 1933) was a Canadian author, lawyer, and the all-time longest-serving Senator.
Born in Shediac, New Brunswick,in a big family, he attended College Saint Joseph in Memramcook, New Brunswick.
At an early age he wrote books on the Origin of Acadian, a history that contredicted myths of the time, multiple articles and language glossary.
After finishing school at the College Saint-Joseph in Memramcook during 1872, Poirier was appointed Postmaster of the Dominion Parliament at age 20.
He held that position until he was appointed to the Senate thirteen years later.Poirier was the first Acadian appointed to the Senate.
He was appointed in 1885 and served for 48 years, 6 months, and 17 days until his death in 1933.
As the Constitution of Canada requires new senators to be at least 30 years old and (since 1965) to leave the Senate when they reach 75, Poirier's record can never be exceeded unless the constitution is amended again to allow it.
The Pascal Poirier House (c.
1820–30) was designated a Provincial Historic Site under the Historic Sites Protection Act.
The home he was born in has been preserved as a museum and as an important and rare example of early-19th-century Acadian residential construction.
