I don't know about Canadian deliveries, as Doug_G hints, but ...
U.S. deliveries of parcel shelves and HPWC seemed to be ramping up (based on forum chatter), though I haven't heard much about the spoilers being delievered. Hence the suggestion.FWIW, I haven't got my parcel shelf yet either. I was told Tesla's plan is to ship them directly to customers' homes.
