Do you think the system will eventually be superseded by heavy rail?
Do you think the Canada Line would ever be converted to an ART system to increase efficiency and capacity?
I feel that though the obvious answer to increased demand would be new lines I doubt Translink will be able to afford this so how do you think Skytrain capacity will be increased beyond the 5/6 car and 3 car options?

Current peak demand on the Expo trunk is 16,000 pphpd. Peak on the Canada line is 6,000 or so.
Both lines could add another 10,000 pphpd before the signalling and platforms could not fit more, and potentially more on the Canada line if trains can be short turned short of the single-tracking. Both lines can be upgraded by more space-efficient seating.
In the event that Vancouver is massively up-urbanized (which would be great) and these lines congest any time soon, I suspect the response would be to build more parallel lines. Main-Fraser, Victoria-Commerical, Arbutus, and the like, which would relieve pressure on the existing lines.
Would the Canada line ever be converted to ART? ART wouldn't increase capacity, and I suspect that there are many other things that could be done to the Canada Line before laying reaction rail becomes the low-hanging fruit of efficiency (like the fact that the Canada Line cars are considerably heavier than the BBD cars). The Canada Line is of a different loading gauge than the other lines, so there isn't too much efficiency to be found in common rolling stock
Heavy Rail? Arguably, the Expo line has sufficient spare capacity that it could be regarded as on the lighter end of a heavy rail system, similar to the Paris Metro. But increasing capacity beyond the hard platform length limits becomes monumentally expensive and disruptive. Much more productive to just build new lines, which if need be can be built to heavy rail capacities
