One important difference is that Indo-Canadians make up about 5% of the Canadian population. It would be surprising if the higher caste subset of that 5% was capable of suppressing access to tenure-track positions across the board. Moreso if it's extended to NA, as the number is ~1.5% in the US. Less if I'm supposed to assume that people from India prefer to work for other Indians, or if Indians are overrepresented in CS academia positions.

I also tend to imagine that those in academia are considerably more likely than the general population to reject racism.

Knowing how those in positions of power can gate keep, yes, those higher caste Indians could easily block tenure. Especially since non-Indians propably cannot really spot the caste based component of those actions.
