Hi,
After this confirmation , you will received work permit by mail . then with work permit and one ID you should go to Service Canada and request SIN .
No one knows about time , but as I see in this forum and 2022 , I found out that this process takes two years from date of PR request submission until ECOPR .
After Eligibility when all stages ( Security - Criminality and Info sharing ) complete , you will receive final decision , then P1 & P2 , then ECOPR and PR Card
The next step is security passed and complete and if all stages for background check complete you receive final decision , then P1 and P2 after that you receive ECOPR and PR Card
I haven't any idea about time.
I received Eligibility Letter after one week that I received prearrival .
not in GCKEY on Email .
You can call IRCC Call center and ask about Eligibility .
