It is funny how adding a simple protected bike lane at-grade with the sidewalk towards the GO station along "Street A" and perhaps "Street B" would resolve the distance to the GO station issue, but because this is the suburbs, that is sacrilege to suggest even in a brand new master-planned community that largely sits in isolation to the rest of the suburbia road network.
There is a bi-directional Bike Lane along the length of both Street A and Street B as marked on the graphic above.
They are beside the sidewalks, rather than in the paved road area.
From the image of Street B above: (close-up and enlargement by me)
The cycle track is the green. There are sidewalks on both sides.
Here's the Transportation Plan:

I disagree with plunking the school in the middle of an existing forest. If you're going to do this, the school should be sited next to the development and the forest should be left in tact. Its a win-win environmental outcome that would also drastically increase 'walk to school'
When you look at the organization of the site in terms of how density is laid out, its a bit dysfunctional:
Street A, the main street, with the shuttle bus has low rise town homes along it at one point, while the highest density backs onto the freeway there, 2-3 blocks away, and that pocket of density is very far from King Road.
You want to pull the density on to street A, and have it lean towards King Rd. more.
I get what they're doing, other than trying to maximize their value first and foremost. They are using the high density as a highway shield (noise/pollution barrier), but they are also placing the density at the north end to mitigate shadow issues.
I have a different solution, build shorter. I don't mean low density, just don't have buildings casting giant shadows that literally can run a km from site..... particularly at the edge of urbanity. Its over-kill;.
If the highest density were lined up along King Rd, with some openings for western sun, you really don't have the same issue. Well done midrise, with a narrow;ish point tower here or there, or a N-S axis slab that tops out at 25s, anchored along Street A would be fine.

I also feel like the site is just too isolated. Connecting it across the 403 and the tracks is no mean feat, it would be pricey, but if you're doing to put density that far in, I think its worth considering.
