Burt Paulin was elected to the Legislative Assembly of New Brunswick in 2003 to represent the electoral district of Restigouche West.
In early 2006, electoral boundaries were redrawn and Paulin's district was merged with Madawaska-la-Vallée to form Restigouche-la-Vallée.
As a result, Paulin, a Liberal, faced off against long time Progressive Conservative legislator Percy Mockler in the 2006 election.
He is the author of a book, Quelques notes historiques sur Olivier, about the history of the Saint-Jean-Baptiste-de-Restigouche area.
Paulin is chair of the combined advisory committee serving the local service districts of Menneval and St. Jean-Baptiste de Restigouche, also serving as an LSD representative on the board of directors of the Chaleur Regional Service Commission.
