Toronto Geography?

Travel Info
Why has Toronto expanded north to Newmarket and inbetween but not as much in the other directions? east and west...

Travel Tips

Well Yonge street was a natural route to take north of the city as well as the DVP/404. Train tracks also lent itself to Go Train service. The other areas have expanded as well. Oakville and Burlington are fairly big on the west and Oshawa on the east. Further east is Cobourg, Port Hope, Belleville and Kingston... again 401 and train tracks are on that route.

Money.... that's always a safe bet. Somehow somewhere somebody is making more money by having ppl settle in newmarket area rather thasn moving farther esat & west
What about Oakville, Mississagua, Bramton, Burlington, Whitby, Pickering, Oshawa, Bowmanville, etc? They're all either east or west and have grown tremendously over the years.
Technically, when you cross Steeles Ave travelling north you end up in Vaughan, or Brampton, or Markham... Toronto-proper cannot expand, it is surrounded. Many small towns have been swallowed up and amalgamated into the GTA. The towns and cities to the east and west have not been made part of the GTA. But when you're driving around, the 'city' just never seems to end.
I agree with "kingstonsean", but I also lived in a little village north of Toronto just 5 minutes from Woodbridge on Islington called Kleinburg, and if you stood at the intersection of Major MacKenzie and Islington and looked south there was the CN Tower in the distance.

And when I was there they were putting in a new subdivision, and the 3 storey brick homes 10 yrs ago were cashing in at $250,000.

Someday we here in Brantford, 30 minutes from Hamilton with a population of 100,000 hope to have GO train service, were are forced to take VIA rail and pay 3 times the cost of a GO train fare.

You must figure the only place in the GTA to expand is north even Brampton and Oshawa are now force to look to there northern regions for expantion, at sometime in the next 30-50 years Barrie will be a suburb of Toronto. So say good bye to the Rouge River watershed and the Halton Morine, progress and housing is more important than wetlands and natural occuring land formations???
Mississauga has grown to over 600,000 , Brampton is growing rapidly, so is Ajax and Scarbourough.
I beg to differ. Toronto has expanded more to the West and East than North or South. South being that there is only the Beaches and Toronto Islands and East is Durham and West is Peel both of which continue to grow and develop at alarming rates and public transit-wise are way more accessible than Newmarket will ever be. Deals with Go Transit have link the East and West and more commuters are passing daily between these points however almost no-one goes to Newmarket or vice-versa-particularly if not driving their own vehicle. Newmarket is basically cut off from Toronto.
