The riding started out as
Northumberland (later known as
Northumberland-Miramichi), and was replaced by
Miramichi from 1988 to 2015, and then
Miramichi—Grand Lake since 2015. The
Miramichi riding consisted of the entirety of
Northumberland County and the area around
Kouchibouguac National Park, adding in 2003 the
Belledune area of
Restigouche County and
Gloucester County as well several bedroom communities for
Bathurst. The bedroom communities of
Bathurst were returned to the
Acadie-Bathurst riding after the 2006 election. The
Miramichi riding was subsequently succeeded by the current
Miramichi-Grand Lake riding, which lost the
Belledune region and gained a portion of the Grand Lake region.
Northumberland/Northumberland—Miramichi The
riding was created in 1867 as "Northumberland" riding, but in 1914 the same name was given to
a riding in Ontario. In 1955 this inconvenience was relieved by renaming the New Brunswick riding to "Northumberland—Miramichi". 83% of the riding came from the previous Miramichi district, and incorporated small portions of
Fredericton (10%),
Beauséjour (6%), and
Tobique—Mactaquac (1%). The riding, gained a portion of the Grand Lake region. Unlike adjoining regions which had been added to the riding in previous redistributions, Grand Lake's name was added to the name of the riding in this redistribution. Following the
2022 Canadian federal electoral redistribution, its boundary with
Madawaska—Restigouche was rerouted around
Mount Carleton Provincial Park and the
Nepisiguit Protected Natural Area, lost the remainder of the
Regional Municipality of Tracadie to
Acadie—Bathurst, gained the remainder of the Parishes of
Maugerville,
Sheffield and
Canning from
Fredericton, and gained
Waterborough from
Fundy Royal. ==Members of Parliament==
