Just would like to make some observations in case it maybe useful to others. This article says that Canada has received 300 percent more students from India in 2018 compared to 2015. That means the number of students have been steadily increasing from around 35000 to around 100000 per year. Now this is 100000 students in one year just from India. Almost everyone one of those 100000 students come here to get PR. Which means as soon as they finish their 8 month course, they apply for their open work permit, start working in canada and get Canadian experience. So after this, every year, there is going to be an increasing number if students entering the pool whenever they feel they have enough Canadian experience points. Canadian experience points can easily push younger candidates score to around 500 points.
Another smaller source of Canadian experience candidates are closed work permit holders from IT companies. This has increased form 2k per year in 2015 to around 9k per year now just from India.
So as the number of candidates from these two route starts filling up the ITA quota of around 80k per year, others will get squeezed out. Slowly if this trend continues it would mean the main way to PR would be by studying in Canada, working on working permit and then applying with Canadian experience.
This squeezing out process will take one or two years two complete, as right now it is the students who came in 2016 and 2017 who are completing one year of work experience now and getting in with higher points. Hence the slow but steady rise in cut off score. the 100k from 2018 will finish their one year Canadian experience in 2020 summer and start getting into the pool we will really see the score sky rocket.
Not to try to discourage anyone,but just trying to analyze what is happening and understand the long term trends.
It would appear in the future, immigrating to Canada would require coming in to study first
