The documents that I submitted through the web form were AOR, Marriage Certificate, OWP Payment Receipt, and Form IMM556E. I wasn't sent any communications asking for those documents, but form IMM556E is a checklist and indicates those are documents that should be submitted with the OWP application. I wanted to make sure the agents had everything.
[Edit:] Oh! And I also noticed on the envelope for my OWP that the permit's CPC was Edmonton -- thought that was worth noting for anyone interested
