Premier Stephen Harper gave support on Tuesday to claims that the 1915 killings by Ottoman Turks amounted to genocide, the source said, a term fiercely rejected by Ankara, which says many were killed on both sides.
"The ambassador has been called back is currently going through consultations over what to do. We don't know how long he will be here," the source said.
"He was called back due to the position of Prime Minister Harper who spoke at a commemorative vigil and whose speech recognized (the events of 1915) as genocide," said the Foreign Ministry source, speaking on condition of anonymity.
Ankara dismisses claims, supported by some countries and academics, that Ottoman Turkish forces killed 1.5 million Armenians in a genocide, commemorated in Armenia on April 24. The Foreign Ministry source said it was not clear when the ambassador would return to his post.
