Today, the legislature is made of two elements: the lieutenant governor (representing the King of Canada)[1] and the unicameral assembly called the Legislative Assembly of New Brunswick.

The legislature has existed de jure since New Brunswick separated from Nova Scotia in 1784, but was not first convened until 1786.

Like the Canadian federal government, New Brunswick uses a Westminster-style system, in which members are sent to the Legislative Assembly after general elections.

The premier is New Brunswick's head of government, while the lieutenant governor represents Canada's head of state Charles III, King of Canada.

The legislature was originally bicameral, with an upper house called the Legislative Council of New Brunswick.
