When you've given notice on a rental are the RE allowed to bring prospective new tenants through for inspections while you're still living there?

Settlement on our new place is next week and we're handing the keys back for the rental in early Sept so ideally we can move house at our own non rushed pace and then clean the old place when it's completely empty. Someone came and chucked a for lease board up today out the front and it says call to make an appt for inspection. But if the RE are bring people through are we expected to keep it tidy? Cos it sure as hell won't be! Or are we allowed to decline inspections until it suits us? I'm really not very savvy with all the renting stuff. Last place we lived in the landlord ending up moving back in so didn't have to deal with all of this. Anyone shed some light on the matter?
