Liberal leader Justin Trudeau was sworn into office Wednesday as Canada's twenty-third prime minister, promising a more optimistic government after a decade of Conservative rule. Trudeau named an equal number of men and women to his slimmed-down Cabinet, the first time gender parity has been achieved in Canada's team of government ministers. The cabinet included rookie politician Bill Morneau as finance minister and former Liberal leader Stephane Dion as foreign minister, a mix of experience and new faces reflected in the rest of the team of ministers. The swearing-in ceremony ended a decade of Conservative rule under Stephen Harper, whose party takes up the role of opposition as they search for a new leader.
