There is no separate francophone NDP community.
You're of course entitled to your opinion, but, well, so am I and I think your reasoning is flawed. Carney did not "save us", the Canadian people did by voting down the poilievrite maple magas. Carney has some interesting policies, such as unifying the internal Canadian market, and diversifying Canadian trade, but in many other ways, my read is that he's laying the groundwork for an eventual right-populist whiplash. His neoliberal policies of firesale privatizations, limiting labour power, lowering environmental standards, abandoning climate adaptation, circumventing indigenous rights, etc are not "the right direction", they are the pillars for a future with more inequality, more "K-shaped recovery", more power concentrated at the wealthy classes and more environmental degradation. In that future, a less disagreeable, smarter fascist will be able to reap what Carney is sowing.
Your framing of the competent leader traitorously being stabbed in the back while saving us, is even already creating the exact schema by which the fascists of the 2030s are going to be enacting the Maga agenda, more politely, more competently, and less cartoonishly than Poilievre or Trump.
The criticism of Carney by the Left is not there to make Avi Lewis prime minister. It's to steer us away from a trajectory that leads to a maple "Meloni-ism" a couple election cycles down the road. It's literally right now the only thing Canada has in terms of actually loyal and constructive opposition.
That said, we also have our own positive vision of what a democratic socialist Canada should be. Feel free to disagree with that as you like. But don't make the mistake of dismissing our criticism of the government as some envious power grab fantasy. Your politics will be less robust and thought out, more cartoonish and more, well, american-ish(!) if you do.
