Absolutely. I have many colleagues who self‑censor or who don't talk about certain topics. If they do talk about certain topics, they must do so discreetly. I have colleagues who lost their jobs because their political views were unpopular. Researchers whose political or ideological views don't align with the majority engage in self‑censorship on a persistent and daily basis.
We live in a free country. When I publish an article, I shouldn't have to worry about whether my colleagues will punish me or whether my job will be affected. Yet that's the reality in Canada. This absolutely undermines academic freedom in Canada.
