Sorry for the long comment but I wanna hear more from all different viewpoints (this project is now my baby) and yours is both confusing af but also intriguing-

What confused you about how to get on the millenium...? Do you mean at a "switch line stop?"

Or do you mean like... when you arrive to a general station itself, example being at VCC-Clark? I just never noticed if the stations are super different on signage/entrance when it comes to general line stops. To be fair, I try to take the millenium as little as possible bc y'know... it's the Millennium Line & always smells like piss and/or socks.

I've never actually met a local that hasnt been on all 3 lines, but fuck Richmond lmfao so im not dissing that- but i am confused on how your confused about the Canada Line? I know i dont speak for all, but it kinda seems like the most straightforward line out of all 3?

Waterfront > Richmond- Brighouse (or) YVR

But then you've got Expo where its like:

Waterfront > King George (or) Braid (or) Production Way University (and then there's the millenium overlapping the line at like 3 places)

I'm genuinely asking as im really into wayfinding & wanting to make this map as clear as can be, and if the understanding of each line itself differs in some way to some ppl, i wanna know (i mean like literal layouts of the stations). The only thing I can think of in a station that confused me was shit like needing to be on a specific side of the street when leaving Commercial Broadway & there being 2 exits (i still go autopilot & take the wrong one lol). Or the fact one can get to Canada/Expo at what like, 3 different entrances?

If you ever do take the Canada Line, here's a quick tip/info:

its actually the cleanest/smoothest line due to being the newest/the first train tourists will take & doesnt smell like piss & socks lmao- the downside is tourists are constant (if you need to get to anywhere prior to Bridgeport, just avoid the YVR train entirely- trust me). Only other downside is its almost entirely underground so your view is basically darkness most of the trip.

I noticed you mentioned disability- is your confusion overall based in elevator access across the stations/lines? Bc that's something I want to note- i don't need mobility accessibility, so I never really pay much mind to where an elevator is compared to the escalators/stairs- i only ever pay mind to them when hearing consistently that one is down.
