What are the next steps after receiving your introduction letter (POE)?

[Locusamoenus]

Hello,

I just received my introduction letter on my cic.gc email box saying that my study permit got approved. It also says what documents I will have to bring but without saying to who, where and why.

My question is what do I have to do next? I have not received a temporary resident visa, nor an ETA letter (I just have my ETA number), I only have my introduction letter.

Thank you very much
