Lately, there has been a temporary hiatus in Ontario sending out PTs. It seems OINP is clearing the backlog which they have accumulated since November (as they had to process Syrian refugee applications). Post this, which I assume would be May 2016 onwards, they would start issuing PTs. My assumption is based on the fact that they have updated OINP settlement funds requirement here http://www.ontarioimmigration.ca/en/pnp/OI_PNPNEW.html. This requirement refers to applications that will be submitted after May 6, 2016.
