In your document, you say that gender-based analysis is done at the outset. Then you say that if it was not done appropriately, you must make corrections before presenting it again to the people concerned. That is exactly what the document I have in my hand says:
However, when preparing Treasury Board submissions [...] federal organizations should proceed with a last check to ensure their proposal is GBA compliant, and report their findings in the TB Submission.
You absolutely must ensure that this is being done at Treasury Board. But it seems to me that you do not need to ensure that it is being done; it is only done under certain conditions, if necessary. I have trouble understanding why it would be stated that something must be done systematically and then not follow up on it afterwards.
