Canada has called for a 'de-escalation and a sustained ceasefire' in Iran. Prime Minister Mark Carney says all parties should respect international laws and the rules of engagement. Although the Canadian government is in a difficult position with the upcoming review of the Canada-U.S. Mexico trade agreement and we live next door to the United States, the prime minister must be more direct in his comments about the legality of this war because it's the right thing to do and puts Canada on the right side of history.
