Your link only mentions landed PR's.https://www.cicnews.com/2023/02/ircc-unveils-the-top-10-source-countries-of-new-immigrants-to-canada-in-2022-0233180.html#gs.5x6l5e
India sends only 27% of immigrants/PRs.
For my own research, I want to know why did you say 80% are from India?
There are many other categories such as international students, visa overstayers, work permit holders, etc.
Those spots are massively absorbed by Indians.
As I said in the past in this same forum, this is nothing against Indians, I would think the same way if instead of India it was Cameroon, New Zealand, etc.
