This is along the same lines. It's the whole issue around when an amendment is significant:
That the current ss. 142(1) and (2), requiring that the Commission or Board give a proponent notice that the proponent has made a significant modification, and giving the proponent 30 days to then notify the Commission of what it has just notified the proponent, be deleted. This convoluted process is not necessary if the proponent gives the Commission notice when there is or may be a significant modification.
I think that's the point. It puts the onus on the proponent to notify the commission if there is or may be...and the commission can then do its work around assessing that.
