I got this information from Guide 3999:
"Certified true copies
To have a photocopy of a document certified, an authorized person must compare the original document to the photocopy and must print the following on the photocopy:
•“I certify that this is a true copy of the original document”,
•the name of the original document,
•the date of the certification,
•his or her name,
•his or her official position or title, and
•his or her signature."

I may be reading too much into the Guide - I'm good at that. It is directly underneath the part of about getting documents translated into English or French. The document checklist says nothing about certifying copies either. However, I took this to mean any photocopy of a document I submit needs to be certified.
Not having to get anything certified would be awesome...
