Mississauga found the density bug when they started running out of greenfield land to develop....a natural progression of suburban communities....until then they were happy to approve the same sort of sprawling, SFD, developments that has built Brampton and will for the next 10 years or so (when Brampton also will run out of land).....the truth is that the vast majority of Mississauga looks like the vast majority of Brampton.
Mississauga has continuously built high-density throughout its history. Most of the high-rises in MCC are from the 80s and 90s for example.
If anything, high-density development in Mississauga actually slowed down after it became built-out.
Look at the list of high-rises built list on SSP: only a small proportion of Mississauga's high-rises were built in the new millenium.
High-rises (12 storeys or greater) constructed in Mississauga per decade:
The 1960s: 14
The 1970s: 73
The 1980s: 50
The 1990s: 46
The 2000s: 35
The 2010s: 21
Total: 260
(not all buildings have dates; the missing dates are for the older buildings)
Mississauga has more high-rise buildings than Seattle, Denver, Baltimore, Hamilton, etc.
In comparison, Brampton currently has 66 high-rises. Brampton has less high-rises now than Mississauga did in the 70s.
That's why we are even discussing LRT in the first place. If high-density was just a recent thing in Mississauga, this thread would not even exist.
Brampton is growing at around the same rate now as Mississauga did in the 90s, but only 5 high-rises have been constructed in Brampton in the past 10 years, compared to 46 high-rises constructed in Mississauga in the 90s.
As I said, it is different culture. People move to Brampton for the lower prices and bigger houses. The new subdivisions in Brampton have very little multi-family housing. Other than Toronto, people who want high-density living go live in Mississauga, or Oakville, Burlington, Richmond Hill, Markham - all those places have more high-density development than Brampton.
That's why I think this LRT is difficult for Brampton. Main is not an ideal corridor for LRT, but people did not move to Brampton for high density living to being with, as you can see from the relative lack of high-density development.
LRT will mean major change for Brampton, but for Mississauga it will just be more of the same.
