Carney danced around it a little bit
"...Canada reaffirms Israel’s right to defend itself and to ensure the security of its people. Canada supports the United States acting to prevent Iran from obtaining a nuclear weapon and to prevent its regime from further threatening international peace and security."
He's not saying directly that he supports starting a war to do it, but implying it for sure. Pretty reasonable position and I would never accuse Carney of blowing sunshine up Trump's ass. In normal times America would have built a coalition with Canada and our other allies before starting this war.
