For us, it was quite simple. My husband and I went to the nearest CIC office at our scheduled appointment time (as we were notified by email). They looked at my husband's passport, took his 2 photos and asked him a few questions. Explained Condition 51 and PR guidelines and then congratulated him on obtaining his PR and told him it would take 8-12 weeks for card and not to travel until he received it.
I sincerely hope they start processing March-August applicants soon - it is not fair.
