Info for 1st landing - documents and port of entry

[razabi83]

Hi guys, I need some info and advice. I received my CoPR (Express Entry - CEC) and I'm about to plan my 1st landing. Could you kindly tell me:
1) which document I need
2) Am I free to land anywhere? Or is there a link between the mailing address I will provide them with and the airport where I'll land?

Thanks a lot
