Prime Minister Stephen Harper is strongly condemning Russia's military intervention in Ukraine and urging President Vladimir Putin to withdraw his troops.
In a statement issued after an emergency cabinet meeting, Harper says Canada is recalling its ambassador from Moscow and pulling out of the G8 process being chaired by Russia.
He warns that should Putin push forward with military action, it will lead to ``ongoing negative consequences'' for Canada-Russia relations.
The special cabinet meeting was called after Putin received permission Saturday to use the country's military in Ukraine, officially deploying troops in the strategic region of Crimea.
The Department of Foreign Affairs, meanwhile, is advising against travel to the region and says Canadians already there should consider leaving ``while it is safe to do so.''
Foreign Affairs says its advisory is due to ``political uncertainty'' and reports of armed groups operating in the area, along with protests and public clashes.
