I think everything is returning to normal. The world will get used to the coronavirus and that is why all program draws are back otherwise there is no reason to bring them back. People will start entering the pool at above 470 as per the pre covid trends.
This is why I am suggesting that international students should finish their undergrad in their home country if they wish to permanently immigrate to Canada.
Things are far from returning to normal as records show. Huge chunk of candidates come from the USA and India. Reports show that the two aforementioned countries aren't close to "normal". Paper based IELTS resumed in India yesterday I think, but at a low capacity than it was accustomed to before the Covid 19 saga. US aren't conducting anything at the moment either, and some states are back to full lockdown until further notice. The reality is that things won't get better until next year at the very least.
I reckon that they only thing that would stuck the draw at 470 is if they pause or alternate between CEC and general draws. If not, the scores would plummet.
For 4months, the number of candidates in the 471-480 didn't increase significantly. Take what you may from the above fact.
