They're the same Rail gauge, they are different loading gauge (eg car width)
Standard gauge is 1,435 mm.
The Skytrain MKII loading gauge is 2650mm.
The Canada Line cars loading gauge is 3M wide (eg more typical subway width)
The JFK version of the same Bombardier rolling stock is 3.10 m. JFK's system is essentially identical to our MKII's except without the articulated connection.
For reference, the TTC, which does not use standard gauge on either it's subway(3.13m) or streetcar LRV's (2.54m) use Toronto gauge 1,495 mm.
It is unlikely that the Canada Line would ever be converted to use the existing MKI/II/III rolling stock, it just wouldn't make sense to. However there is nothing stopping them from ordering cars from Bombardier that use identical parts to the MK/I/II/III save for the propulsion system (the Riyadh Metro line 3 uses the same cars, on Mitrac propulsion, look at
http://www.metro-report.com/news/single-...ery-of-first-bombardier-metro-train.html to see the height difference, and note that it's sitting on the LIM track.)
So if Translink wanted to save money on maintenance they could just get trains built by Bombardier for the Canada Line. The reason they wouldn't currently is that the PPP contract would not let them to. The Private operator would have to order things, and likely by running a new RFP.
Likewise Translink could always do the same with the Expo line. I'm sure the same company who made the Chinese version of the Innovia Metro in China would love to bid on it, or even other LIM-based metro cars in Japan. The main issue really is not who we get it from, but standardization of parts. It simply does not make sense to have too many unique systems, because that means you need to have more maintenance staff to manage each version. That is typically why in places like Toronto and New York, once they order new trains, they decomission the oldest ones.
The fact that all of the LIM rolling stock is able to run anywhere on the LIM tracks is a plus, even though from a marketing point of view, it's really more like 4 systems (Expo Waterfront to Columbia (1985, with Columbia 1989.) Expo Columbia to King George(1994), Millenium Line Columbia to VCC(2002 VCC 2006,) and Millenium Line Lougheed to Lafarge Lake (2016.) We just consider the entire Expo line one line even though it was built as two pieces.
This is why there is a lot of noise about the Surrey LRT boondoggle. It's not rapid, it's not frequent, it's not automated, it doesn't work with ANY of the existing rolling stock systems or power systems... and they haven't even RFP'd for rolling stock yet. We know this already because of them wanting to run it down the median of what are essentially highways. It doesn't take a transportation planning engineer to tell you that this plan is going to be a bottomless money pit. You can not consider capital costs alone when planning rapid transit. In nearly every BRT vs LRT argument, the BRT always wins, but the city goes with LRT anyway because they promised their voters a train.
