No it didn't. He gave it as an example of something people behind the Iron Curtain didn’t believe but parroted "to avoid trouble, to signal compliance, to get along".
The man is a banker. The implication that Carney - arguably the most neoliberal leader Canada has ever seen - is a communist is absurd.
He was referencing the words of a writer from Czechia, a country where communism discredited itself, who discussed how people pretended not to notice the gap between the government's rhetoric and its actions, and compared it to how countries politely have pretended to ignore the gap between the aspirations of the "rules-based international order" and how it played out in practice.
Of course, he could have used as an example a different dissident who said something similar from a different country who operated under a different totalitarian regime. Or skipped the analogy to political repression altogether. You could say that reflects Carney's particular biases, I guess, but I wouldn't go further than that. At no point does he ridicule or even mention unionization.
