Well, it looks like Grouse Mtn is finally opening in a couple of weeks, June 22. You will have to book your ride up/down in advance (1 up/down per day), wear a facemask, and get your temperature read prior to boarding the tram. Trams will run at 30% capacity and have all the windows open.
Sea to sky gondola has been open already for a couple of weeks, for pass holders only I believe. But I guess it's easier for them to manage with people going up and down in smaller capacity gondolas.
