There are pretty much no longer Drawing Rooms (VIA-speak "Cabin for 3") on the Canadian at all. It runs with a "Prestige Park" car where the Drawing Room and Double Bedrooms have been removed in favor of a Prestige room and an Accessible room. Sleeper Plus is exclusively supported by Manor series sleepers that never had Drawing Rooms. Very occasionally an non-Prestige Chateau used to show up when hard up for cars, but I haven't seen one in revenue service for a long time and summer consists are a bit shorter than they were pre-COVID. They used to run Chateaus as crew cars (the SM got the Drawing Room), but the last couple years even those have been Manors.
