For those waiting a long time for PR card after sending photos last year:
I was in a similar situation. I had originally sent my photos to "IRCC-Winnipeg PR landing photos". After waiting for 7 months and no response, I re-sent my photos and a letter explaining the situation to the same office. And voila, next day my PR card application got approved and after 3 days got my PR card in hand!
Surprisingly the card came from the Nova scotia office and has the photo that I sent last week (not the original one).
So go ahead and resend your photos to the same office where you sent originally and remind them that its been more than 6 months!
My guess is that they lost our applications/photos due to the Covid situation.
