I know this thread has wandered in many different directions, and this is not intended as a simple city vs. city post. It’s a response in part to media reports like
“Toronto set to over-take Chicago in Skycrapers” which I’m betting often use a 100 metre or taller “yard” stick. For the record, I love Chicago, but just not warts at all. This post also touches on my scraper pet-peeve: CTBUH’s maze of height criteria that often raises more questions (and arguments) than answers.
INTRO:
Like many others, I remain befuddled with The Council on Tall Buildings and Urban Habitat’s (CTBUH) height criteria* and definitions.
They don’t even define a “skyscraper” despite running a website ironically called the
“SkyscraperCentre.com”. This is the ruler they use:
1. Tall: 50 meters+ (165 feet)
2. Supertall: 300 meters+ (984 feet)
3. Megatall: 600 meters+ (1,968 feet)
So what’s a skyscraper then? I have made my choice below, but it’s up to you. Here a some examples of what I characterize as the
CTBUH Muddled Height Index:
1. One World Trade Center has a roof that tops out at
417m (plus a 10m donut), yet its glorified (Canadian-built) antenna,
held up with guy wires, has earned it an official height of 541 metres (much-beloved 1776 feet).
2. Chicago’s Willis/Sears has a roof height at
442m (CTBUH’s “official” height) but has it 2 enormous
free-standing masts that top out at
527m. But the masts don’t count because they are functional not architectural… huh? BTW when is a mechanical penthouse 'architectural'? When it's pretty?. So
1 WTC has a 417m roof and Willis has a 442m roof. Which 'building' looks taller? Pictures don’t lie IMO.
While skyline favourites are of course subjective, and even statistics are open to interpretation (like I’m doing), media stories I mention earlier like “Toronto Passes Chicago In Skyscrapers”, are often met with derision outside of The Six. Of course CTBUH has no official name for a 100m "building metric" (but you can search it like the media likes to do).
Brief Tangent using the media’s preferred 100m metric with my +/- 1m rider:
100m or taller (+/- 1m):
Built and Under Construction
TORONTO 333 (Source: CTBUH) + 23 (Source: SSP) = 365 (note: Toronto also has a huge lead in 100m or taller proposals)
CHICAGO 337 (Source: CTBUH) + 13 (Source: SSP) = 350
Personally I think (and many might agree) that a “
skyscraper” is 150 metres+. For this post I am using a baseline of
150m plus/minus 1 metre - it seems a bit silly to me if half a dozen buildings .3m short of this 150m threshold don’t get counted, so even though close only counts in horeshoes, it counts here too
.
EDIT: Please note there is an error in my chart below - CC3 is actually 376m to the tip of its spire.
TORONTO AND CHICAGO COMPARISON
By the 150 Metre Numbers
Wrapping up - My subjective choice: In the near future, Chicago will still have taller buildings than Toronto ( 400m is not impossible in The Six eventually), but for fun I decided to add in just
25% of the Toronto proposals (24 skyscrapers) and
25% of the Chicago proposals (3 skyscrapers), to arrive at my informal built-construction-proposed
snapshot:
TORONTO = 119 skyscrapers (using my 150m +/- 1 metre metric)
CHICAGO = 105 skyscrapers (using my 150m +/- 1 metre metric)
So Toronto will one day be
the number 2 skyline in North America imo. My forecast of 14 more legit skyscrapers than Chicago, a half dozen distinct tall, dense, and growing
clusters in a vast ebbing and flowing skyline from North York to the lake... and the tallest free-standing structure in North America (553m), which some folks like to ignore because it’s not considered a “building”... but it has been and remains a skyline-changer in almost every Toronto photo - for me CN mitigates the absence of a plus 400m monster like Willis (Sears), and it belongs in a skyline discussion.
Have fun. Cheers.
POST-SCRIPT: Some CTBUH Data Notes, Questions and Observations (Supertalls as defined by CTBUH):
1. SPIRES/ARCHITECTURAL TOP VS ROOF HEIGHT
Chicago Franklin Center - built -
270m roof + arch top/spire = 307m (4 wafer-thin, nearly invisible toothpicks on the roof make it a CTBUH "spire" Supertall)
Toronto The Hub - proposed -
258m roof + arch top/spire = 304m (thx cbtuh ;-)
Toronto CC3 - proposed -
302m arch top (curtainwall screen) + spire = 376m (hey it counts for One WTC lol ;-)
2. ANOMOLIES - CTBUH HIGHER ARCHITECTURAL TOP/ROOF REPORTED
CTBUH - 55 Lakeshore East B proposed -
304m (Note: already included @299m in my supertall total,
using +/- 1m)
* reported on UrbanToronto and SSP Diagrams as
299m - *CTBUH may have added in a 5m mechanical penthouse (?)
CTBUH - 55 Lakeshore East C proposed -
304m
* reported on UrbanToronto and SSP Diagrams as
290m. This CTBUH data may be just out of date.

As to the inevitable troll replies, everyone knows you think everything built locally is crap, but I challenge you to post something on topic instead.
On second thought spam away (I need to improve my reaction anyway).
