As per below, for CEC/PNP applications, the AOR email seems to be enough. For Federal Skilled Worker, you need the positive eligibility assessment.
Although there is some confusion as to where the automated AOR email originates from. Some people on this forum claims that that email comes from CIC and not CIO (Ottawa), and thus, cannot by itself be sufficient for BWOP.

For the purposes of determining if a positive eligibility assessment has been made, the processor will review if the Eligibility Assessment value is set to “Passed” in the Global Case Management System (GCMS). If this decision has not been entered yet, for the purposes of these instructions, a “positive eligibility assessment” will also be considered made when the following is confirmed in GCMS:
-For FSWP applications, the status of the Ministerial Instructions activity has been set to “Met” or a positive Final Determination of Eligibility letter or e-mail has been sent.
-For PNP applications, the status of the Eligibility EC-QC/PNP activity has been set to “Passed” or the Acknowledgment of Receipt letter or e-mail has been sent by the Centralized Intake Office (CIO).
-For CEC applications, the status of the Eligibility CEC activity has been set to “Passed” or the Acknowledgement of Receipt letter or e-mail has been sent by the CIO.
-For FSTP applications, the Acknowledgement of Receipt letter or e-mail has been sent by the CIO.
