Canada's ambassador to Iran has been ordered to leave the country by Teheran, the Canadian foreign minister said late Monday, calling the move entirely unjustifiable. Foreign Affairs Minister Maxime Bernier suggested that the expulsion of Ambassador John Mundy, who was recently appointed and yet to have his credentials accepted, was a tit-for-tat move by the government in Teheran. Canada and Iran have tried to come to an agreement on an exchange of ambassadors for some time, but Canada is not willing to accept the candidates Teheran has proposed thus far. "We believe that the expulsion of our ambassador is an unfortunate and unjustified consequence of this situation. As always, Canada remains prepared to receive an Iranian ambassador provided a suitable candidate is presented."
