Until Doug Ford's Ontario government launched a two-week U.S. ad blitz challenging the Trump administration's trade practices, Ford and Prime Minister Mark Carney were getting along swimmingly. Since their breakfast get-together at a Toronto-area diner in mid-March, things between the two were all handshakes and smiles. At that point in the Ford relationship, Carney had little leeway for complaint. Toronto's mayor was firmly opposed, as were most of the residents of the forest of condominiums erected along the shoreline. In those first brotherly days, both Carney and Ford were riding high: a popular new prime minister and a premier celebrating a third majority victory.
