...so what does it take to get their fingers out and put one there? It doesn't have to be fancy or elaborate...just nice, easy and practical.
Money would be helpful. You also need landing points on both sides.
Make it a requirement to gain approval.
Not feasible. You can ask, but not mandate that.
Moving is never easy but why do they seem against swapping out a nearly 60 year-old building for a brand new one involving just a slight relocation?
I don't know if @ADRM could add anything here.

In respect of adding a bridge (or tunnel).
Its not a cheap endeavour.
The simplest version requires a ramp, ideally at a 5% or less gradiant so as to be considered accessible (you can do stairs or a steeper ramp, but you then need an elevator to achieve accessibility).
A 5% grade, when you need to clear the rail corridor at a height that allows for GO Trains, and then overhead catenary on top of that you need a fair bit of distance.
For clarity, Mx requires you clear their tracks by at least 5.3M, and at a 5% grade, a ramp would be ~100M long to reach that height. Even with one switchback, that's still 50M'ish...
That's a lot of real estate.
The alternative, add elevators, is costly you need one on each side, they have to be weatherproofed etc.
That's not to suggest it isn't do-able, it is. But its a substantial ask and would be hard to justify given the current project size/layout. Easier if the school site were included.
