Honestly, it depends on your experience, educational degrees, single applicant/family etc.
Regarding the process which I know is. Express Entry Process wherein you need to get certain points which is called CRS points. As per the latest trend, 450 points was cut-off in April to get an invite. Though people expected the cut-off to go lower in May, it actually went up to 470 which is for the first time it happened and it was scaring for us all. If you have CRS points above 450, you have very high chances for PR.
Points are calculated based on the tool, would request to check your points below:

Remember, need to clear IELTS with band Listening - 8, Reading - 7, Writing - 7, Speaking - 7 which gives extra 50 points in CRS Calculator. (If you get more than this, there are chances to get high points in CRS).
IELTS 8777 band score is also known as CLB9 (and if you score CLB10, your CRS points can increase, as I told above).
