The Nunavut and the Northwest Territories operate on a consensus model of government. 

As with the provinces, Nunavut and the Northwest Territories are comprised of a legislative, an executive, and a judicial branches. The Legislative branch consists of the Legislative Assembly and the Commissioner (a role similar to that of Lieutenant Governors in the Provinces). The executive branch refers to the Premier and their cabinet and also includes the Commissioner, while the judicial branch refers to the court system. 

The key difference is that Members of the Legislative Assembly are elected as independents rather than as affiliates of a political party. Once the election has concluded, the Members select the Speaker, Premier and Ministers from amongst themselves in a secret ballot election. The Commissioner, appointed by the Governor General, is then responsible for formally appointing the Premier and the Ministers. Importantly, although the number of cabinet seats is not fixed, it cannot be a majority of the Members.
