Canadian Prime Minister Mark Carney will announce his new cabinet on Tuesday, May 13, at 10:30 a.m. at Rideau Hall. Governor General Mary Simon will take the oath of office.

Sources tell CBC that the cabinet could be expanded to include a two-tier structure: a core of senior ministers and a second tier of ministers without portfolio. A similar model is used in the United Kingdom, where Carney previously served as governor of the Bank of England.

The goal is to keep the core structure small, unlike Justin Trudeau's cabinet, which had 40 members. Carney's first government had just 24 ministers.

Cyrus Reporter and Marc-André Blanchard are being considered for the post of chief of staff. Blanchard, however, has said he is not in talks about the appointment.

Carney's first cabinet included 13 men and 11 women. Some civil society groups have previously criticized the reduction in the number of ministers responsible for specific areas that Trudeau has promoted — women's rights, youth, language equality, disability, and others.

The new government will receive a raise to the base salary of $99,900, while the prime minister himself earns about twice as much as a typical MP — $209,800.

Parliament returns to work on May 26. Carney has promised to begin implementing some initiatives from the first days — the abolition of barriers to interprovincial trade, free access for young people to museums and Via Rail, as well as to national parks this summer.
