"It seemed like a good idea three years ago when oil prices were cresting $140 per barrel and pipelines appeared ready to link Asia with Alberta crude: build a record number of office towers to cash in on Calgary’s oil-fired bash.
The party ended hard, however. Alberta’s biggest city has nearly a quarter of its downtown office space – 10 million square feet – empty, with more surplus space being shoved back onto the market every month
There is also more than 1.5 million square feet of office space under construction downtown that will be completed over the next 18 months."
