Interview to finalize PR officially - PHOTOS required??

[Phe]

Hi guys

I received my PR visa and COPR a few weeks ago. I have been residing in Canada for the last few months on a TRV so booked an appoinment/interview with CIC to do all my landing procedures within Canada (so i dont have to go through the trouble of leaving the country and re-entering).

I got my letter yesterday confirming the date/time of my interview. On the letter it states to ensure that "both" photos i bring meet their requirements. I am confused. On my COPR there is already a photo of myself attached, what do they mean by "both" photos? Before CIC issued my COPR and PR Visa, i sent them 4 photos according to their requirements (only one was sent back to me attached to the COPR). Can someone please clarify what other photos i am required to bring with me to the interview apart from the one attached to my COPR?

Also does anyone know what other documents i am required to bring other than my Passport with PR visa intact?

Thanks so much
Phe.
