TORONTO — Justin Trudeau was sworn in Wednesday as Canada’s new Liberal prime minister, promising a less controlling style of “government by Cabinet” after almost 10 years of Conservative rule under Stephen Harper.

The 43-year-old Trudeau, a former school teacher and member of Parliament since 2008, became the second youngest prime minister in Canadian history.

“Government by Cabinet is back,” Trudeau said, vowing to have an open and transparent government. Power in Harper’s government was centered around his office.
