Nowadays its delayed more.
I used to get it on time within a month whenever i requested using information act but this time its more than 5 weeks and i havent received the notes using privacy act. But people earlier have noted in forum that they were facing delays using information act too.
Some posted that it takes nowadays 2-3 months to get it. I think that its due to more number of people in backlog at cic leading to more number of notes requests(also may be resource crunch too)
