Can he not create a new profile, an additional one in EE?403 it will soon be.... but haven't you seen ppl writing about how Ontario is sending notification to profiles that are recent....some seniors had deleted their old profile just to secure Ontario NOI....
but you may wait till the next draw...it will clearly indicate the possibility of CRS dipping below 400...
I feel because despite the long gap btn draws and the new changes,if the cut off doesn't go up substantially,then subsequent draws may lead to a lower cut off...and if there are back to back draws in June (that is two draws across 15days) there is very good chance of cut off at your levels...so it may not be wise to give up ur vintage over the next one week by deleting current profile trying to secure an NOI from Ontario...
