Yeah buddys in this forum said it, and if u take a look about everyone's timeline u will believe it. It starts counting time since u receive AOR. And they process ur case like u did ur homework at school, stick to the deadline LOL.
buddy they have 1 year deadline to process ur case, unless u r a lucky man, they will stay to the last month, lol. At least u know the deadline, some people here had around 10 months silence from IRCC.
