That is very likely and you can thank the computer for that.
50 years ago large offices were needed for all the employees a company would need. They would be full of typists in the Steno-pool, accountants with adding machines, hundreds of file clerks in vast filing rooms, and mail rooms the size of a Shoppers Drug mart.These days all that is done by one overworked Soccer mom late for her Go train.
OK I exaggerate but the realities of corporate office space has definitely changed with the advent of the computer. Even the rise in telecommuters has reduced the amount of space many companies need.
Sadly, the need for the Empire State buildings of the world, is dwindling with each technological advance, yet the desire to live in such a great city like Toronto is increasing. Therefore we get lots of Condos and fewer and fewer office towers in comparison.
