Deadline for documents

[youngprod 3]

i was wondering if there was a deadline for people to submit supporting  documents to school. i was trying to look around on school websites and the most i could find is that they require you to submit them through ouac. is there a fixed date which all ducuments were required to be submitted by? and if they are submitted afterwards are they not considered at all? thank you.
