(Adds Freeland comments, background)

OTTAWA, June 6 (Reuters) - Canada will seek to play a larger role on the world stage as the United States retreats, Foreign Minister Chrystia Freeland said on Tuesday, in remarks underscoring strains between Washington and its closest allies.
Freeland spoke after recent NATO and G7 summits where U.S. President Donald Trump upset leaders to such an extent that German Chancellor Angela Merkel expressed doubts about the reliability of the United States.
Freeland, noting "international relationships that had seemed immutable for 70 years are being called into question," stressed the value of bilateral ties with the United States, traditionally seen as Canada's closest friend. She also made clear those bonds might loosen.
"The fact that our friend and ally has come to question the very worth of its mantle of global leadership, puts into sharper focus the need for the rest of us to set our own clear and sovereign course," she said in an address to parliament outlining her foreign policy vision.
"For Canada that course must be the renewal, indeed the strengthening, of the postwar multilateral order," she said.
Trump, elected on a promise to put "America first", accused North Atlantic Treaty Organization allies of not picking up their fair share of military spending and then announced he was quitting the Paris climate change pact.
"Canadians understand that, as a middle power living next to the world's only super power, Canada has a huge interest in an international order based on rules," said Freeland.
Canada, she said, would "strive for leadership" in multilateral forums such as the G7, the G20, NATO, and the United Nations.
She said NATO and Article 5, the alliance's mutual defense doctrine, lay at the heart of national security policy. Trump upset NATO leaders by not personally affirming his commitment to the article.
For Canada to play a larger role globally, it would need to make "a substantial investment" in its armed forces, she added. Officials are due to unveil additional military spending on Wednesday.
"Canadian diplomacy and development sometimes require the backing of hard power," she said. Canada spends less than one percent of what the United States devotes to defense.
Freeland said Canada was deeply disappointed by the decision to leave the Paris pact but made no other criticisms of U.S. policy. Canada will soon start talks on renegotiating the North American Free Trade Agreement, under which it sends a majority of exports to the United States. (Editing by Jeffrey Benkoe and Diane Craft)
