This article provides a summary of results for the general elections to the Canadian province of New Brunswick's unicameral legislative body, the Legislative Assembly of New Brunswick. Prior to 1892, New Brunswick had a bicameral legislature, but its Upper House – the Legislative Council – was not elected. The number of seats has varied over time – from 41 at the time of Canadian Confederation, to a high of fifty-eight from 1967 through 1991, to the current level of 55 since the 1995 election.
Beginning with the 37th New Brunswick general election in 2010, elections in New Brunswick are – in general – held on fixed dates on the fourth Monday of September every four years. The date may be varied by one week earlier or later in cases of the fourth Monday of September being a date of cultural or religious significance and may be varied one month earlier or later in cases of a federal election being held during the same period. The Lieutenant-Governor of New Brunswick also has the power to call an election on another date in the event of a loss of confidence in the legislature.
The chart on the upper right shows the information graphically, with the most recent elections towards the right. It shows that New Brunswick has effectively a two-party system – the Liberals (red) and the Conservatives (blue); along with the one-off success of the Confederation of Regions party (green) in 1991. It also shows the Liberal party's clean sweep of seats in 1987, one of the few instances in history when a party won all the seats in a national or sub-national legislature. Since provincial parties were officially recognised, the Liberal party have won eleven out of twenty elections.
