Downton office vacancy rates hit +30% in 1982 and towers well under construction were halted. I remember being depressed reading that another tower would not be built for 30 years. Then we got Canterra & Bankers Hall East completed in ‘88 & ‘89 respectively and a fairly regular stream of towers after the 1990s.
You’re right about Suncor being the tallest for a long time though (28 years I think). Then we had a glorious burst with The Bow, EAP, Brookfield & Telus Sky.
I don’t think the next tallest will be an office tower although there may be an office component. If it’s another 28 years your prediction of 2050 will be pretty close
I’m really hopeful it’s much sooner than that though.
