The question was, whether he supported the move. He said he was no longer chair when the formal decision was made, despite documents showing the relocation, which he supported and encouraged shareholders to support in a letter, was done during his time as chair. His argument is that the formal decision was made after he left, which sounds like a distinction without a difference and some would consider lying. He later said he should've been more precise in his answer. If he had said he supported the decision because company executives thought it was in the best interest of shareholders, the story would've gone away.'he said he was no longer chair when the formal decision was made'
That's technically correct according to what you posted.
Where is the lie?
But now the Conservatives and some media are going through his various public claims about his career. Now there's some question to his remarks about helping former Liberal finance minister and prime minister Paul Martin with the deficit in the 90s, when Carney wasn't working for him. Another lie? Or will he say, that's not what I said/what I meant.
Carney's issue is that he doesn't have experience as politician and not getting your story strait or bending the truth can come back to bite you in this game. Love him or hate him, Poilievre is a seasoned pro. Carney better watch out when the gloves come off.
