I'm not sure what Unionville had before..............but when it comes to platform canopies, the minimum standard is the functional one; does it stop you from getting rained on, if you are underneath it?
If the answer is no; then that's a fail.
If the answer is 'yes' then we turn to aesthetics.
My take, having not tested it; is that the weather protection looks inadequate.
Aesthetically, its a bit pedestrian in general; but I'm more particularly at odds w/how it fits w/the Unionville character. Its both bland and out of step.
Is it horrible? No........does it reach the standard that I would hope for? Also, No.
At least w/the tunnels, its not a place one would expect to spend time; also, they've managed to get natural light into this one.
Certainly it lacks colour, or 'finishes' of any kind really. But I find it less obnoxious relative to the surface areas in that its less visible and more of a transient space.
Still, it would certainly be nice if they put more effort into it.
