Unfortunately, Vancouver city planning never allowed for any bus tunnels or bridges, especially under/over Burrard Inlet, False Creek & the Fraser River. All the underground train stations weren't built to easily become as long as the Montreal Metro stations, which are 152.45 m or 500 feet.
Vancouver & the Metropolitan Region have done so many things wrong. The train stations are too short & most of the bridges are so narrow, there is no room for bus & HOV lanes. By now, there should have been a regional network of rapid bus & HOV bridges, because most of the existing bridges have just 2 lanes each way.

Seattle, Perth, Calgary & Edmonton have been able to do so much more, because they don't have to contend with anything like the backwards mentality of Vancouver & BC.
