r/Canada was taken over by right-wing mods, including some fsr right extremists and at least one open white supremacist.
The sub isn't made far right though. The moderation is more subtle, with clear bias in moderation regardless of source.
Articles critical of right-wing parties, policies, and politicians (even fact-based pieces) will often be silently removed, often for being "repeats" since there are multiple articles from different sources about the same topic. So only one post will stay up. Yet "repeats" of articles critical of left-wing stuff are allowed, as are "repeats" of non-political topics.
Comments are not as heavily moderated, but left-wing biased comments are more targetted.
Outright racism is generally removed. But plenty of comments talking about "certain types of people" or "people from certain countries" are allowed... unless those comments are talking about white people or Canadians, in which case even those "subtle" comments are removed for "outright racism". The up/downvotes also tend to follow this trend.
The sub got to this point probably around the pandemic, when Canada's explicitly far-right extremist sub, r/MetaCanada got shutdown. The userbase migrated to r/Canada, and some of the mods from r/MetaCanada were welcomed into the r/Canada mod team (including the aforementioned open white supremacist). The right-wing extremist mods also started pushing out the more moderate, centre, and left-wing mods.
It's the kind of shitshow that an outsider would never notice. Makes me sad that they have the "official" name, just r/CountryName...
