true yet people don't seem to realise it. Most people automatically move to low density suburbs after they are married 20km away from where they work, and then complain about the lack of good transit and expect the city to build subway to their houses. it is not reasonable.
Even the city of Toronto itself is very very sprawling, not to say the GTA. We might have relatively high density in the NA context, but that's a very very low bar and isn't exactly something we should be glad about - most NA cities don't have and don't deserve good public transit because of the way people choose to live.
I am of the opinion that the entire 2.8M Toronto population should live on half of the land we now occupy (imagine Toronto without Scarborough and Etobicoke). With that kind of density, we can build efficient rapid transit much more cheaply and efficiently. With low density, it is very hard and expensive to do so.
For example, on the Yonge line, The stretch between Eglinton and Sheppard is of very low density, with mostly single family homes on both sides, yet we need to extend our subway that far in the north because people live there. If it had half of the density of downtown, it won't be that hard to build transit.
The Spadina line and BD line are even worse. Even with existing subways, nearby neighbourhoods are of much lower density than they should be - still largely low rise (under 3 stories tall), which means hardly enough people live within walking distance. Ideally the subway routes should be dominated by mid and highrise buildings providing shelter for 5 times the number of people.
Dupont and Castle Frank stations are quite close to the core, yet this is what you see after exiting the station

We are not using areas well served by existing infrastructure, yet complain about we don't have enough of it.
If we build more housing supply and amenities close to existing subway stations, and try to sacrifice some space in choosing a home by living in denser neighbourhoods, we won't have to complain about transit nearly that much.
Both the city and its residents are too blame for the problem. The former for its bad planning and latter for its insatiable appetite for space in the suburbs.
