The real focus here should be GO transit - even with a ROW all the way down Yonge it's still a very long trip to Hi-way 7 or Finch or downtown.
There's no density here and no real plans for more to be added - yes it's a place to go region but it's all singles / attaches (some townhomes).
This isn't even a bad thing in my mind - this is too far North, we have a lot of other areas to focus on in the southern GTA section.
There are two problems here.
1) There ARE real plans for more density. It is earmarked in Places to Grow as a growth node so there WILL be intensification. Anyone who has driven the stretch near YR HQ is can see how ready the east side of Yonge is for intensification. It might not be 30-storey towers all over the place but it will certainly be different from what's there now.
Since detached houses in Newmarket average something like $330K, I expect any condos would be cheap and the region is already looking at intensification on land they own along Eagle Drive.
I'm not going to link to Newmarket's OP but it's all in there already.
I will say that Newmarket was one of the first munis in the province to get its OP in conformity with Places to Grow so I'm not sure where someone could say they were "dragged kicking and screaming" into doing so.
2) When you say it's "too far north" and that it's a long route to take transit to Toronto you miss the entire point of Places to Grow (ie the province's planning law).
The point isn't to make sure everyone can get to Toronto - it's to create pockets of intensification all over the GTAH. Newmarket's intensification has little to do with Toronto, beyond the obvious GO connections.
The point of intensifying is to help Newmarket and York Region stop sprawling.
I don't have the province's map in front of me but there must be 20+ growth nodes mandated.
If all you can do is look at it and say, "Gee, what's the point of intensifying in St. Catherine's - it's so far south of the city!" you're really missing the central point of the entire planning regime, which is to create work-live spaces in the suburbs so not everyone is driving to/from downtown Toronto.
Then you have Metrolinx weaving together a big network of which Toronto is obviously a key part, and I can see you're not the only one in the thread to make this mistake but it's amusing (particularly on the Yonge subway thread) to see how many people assume that the only point of transit is to get people downtown. It isn't.
(For the record - I'm not 100% sold the Davis Stub but there is A LOT of employment going on in that area and it is a traffic mess so, all things considered, I'd say it's probably the way to go.)
