it is strange though if your travel date was 30th may. Both should have been sent together. I always think with study visas and all , early arrival might be problematic for students i mean they can be questioned by immigration officers it is better to arrive near to the class start date.
in your case really have no idea your date is well past now and you are still waiting for your ppr.
very strange though.
did you attach any confirmed flight tickets or hotel bookings if you are going there as a tourist.
or your pupose of travel was different.
Nobody should be purchasing plane tickets without approval. IRCC warns people not to purchase tickets. A proposed itinerary is fine
