LONDON - Justin Trudeau is heading home from a lengthy, three-country foreign tour in which the prime minister appeared to recapture his international mojo and reassert several key alliances, but didn't sign off on any big deals or declarations.

When the 10-day trip to Peru, France and the U.K., with a quick stop in Ottawa, started last week, one of the top questions was whether Trudeau could rediscover his footing on the world stage after recent controversies in China and India.

This time, there were no eye-catching outfits as Trudeau stuck to tried-and-true business suits and, on occasion, his patented button-up shirt and rolled-up sleeves as he met with world leaders, industry representatives and students.

There were no noticeable gaffes or tensions as the prime minister pushed his progressive trade agenda, women's rights and ocean protection while issuing warnings against rising authoritarianism and inequality around the world.

Mixed with those higher ideals were closed-door discussions -- first in Peru with Mexico and the United States about the North American Free Trade Agreement; and then in the U.K. about Russia, Syria and cybersecurity.

The prime minister didn't make it easy on himself, either, as he flew briefly back to Ottawa from Peru to meet with the premiers of Alberta and B.C. on the Trans Mountain pipeline, and then onto France, rather than directly to Paris as originally planned.
