I agree.
But I think its important to illustrate for newcomers to the discussion why there is no easy solution here; or for that matter a moderately over-priced and less than effective one.

There is no underground connection available today, or easily buildable, even as a straight walking connection, never mind with movator (flat escalator/moving sidewalk)
There is no other practical way (sky bridge?) to make the connection any easier/quicker at really any cost, but certainly any vaguely reasonable one.
The best available option is really one of making sure there is adequate sidewalk width, some streetscaping, and maybe, at a push, some weather protection (canopy)
****
To truly make this connection more efficient; you need the two lines closer together; this is only achievable by either moving the GO Line(s) north, almost certainly underground, quite deeply.......or by pushing the subway tunnel south (with the small matter of the bus terminals current location).
To be clear, the above is absurdly costly...........and is unlikely to be worthwhile achieving, if not ever, then certainly in the near or medium terms.

@reaperexpress I know you know all of the above, I'm just putting it out there for those who do not.
