You might be right...They are processing PR Cards - I know of people who have received theirs.
They seem to be processing it for those who sent their photos to smaller IRCC offices like Windsor, Etobicoke, Niagara.
The bigger IRCC offices do not seem to be processing any cards..it's very frustrating and makes no sense.
Some people are getting theirs within 3 weeks, others are waiting months.
I sent my PPR documents to Ottawa in March and I'm still waiting for the card.
