He definitely has talked like that at earlier EU Canada economic forums and made several concrete steps in trade diversification in the months before the speech, so it's not a sudden about face.

But I still can't help but notice he talks a lot differently at European forums than over here, I wish he talked to Canadians like that more often. I don't fault people if they wonder whether Carney's serious since he has also made moves that appeared to appease the US, while in part of the speech Carney says middle powers including Canada should stop doing that.
