Paul Martin was sworn in as Canada’s 21st prime minister Friday, and he unveiled sweeping changes to the federal cabinet.

Martin’s cabinet will have two westerners – Ralph Goodale of Saskatchewan and Anne McLellan from Alberta – in the most senior portfolios as finance minister and deputy prime minister respectively.

McLellan had been health minister, while Goodale was in charge of public works. The appointment of Goodale was widely anticipated.

Martin dropped 22 of the 38 members of Jean Chretien’s cabinet, retaining 16 veteran ministers. The size of cabinet – 39 members including the prime minister – remains unchanged.

Among those leaving cabinet: Sheila Copps from heritage, Lyle Vanclief from agriculture, Elinor Caplan from revenue, Martin Cauchon from justice and David Collenette from transport.

Among those kept on: David Anderson retains environment; Pierre Pettigrew will hold the dual portfolios of health and intergovernmental affairs; Bill Graham keeps foreign affairs; John McCallum is moved to veterans affair from defence; and Lucienne Robillard is shuffled to industry from Treasury Board.

Newcomers include: Defence Minister David Pratt, Transport Minister Tony Valeri, Justice Minister Irwin Cotler and Agriculture Minister Bob Speller.

Allan Rock, former industry minister, becomes Canada’s ambassador to the United Nations.
