On that note, here is another timely article on the topic of residential conversion:
City council has approved the terms of reference for the Downtown Office Demolition Incentive Program

I imagine this is also somewhat relevant to Edmonton as many of our older office buildings were constructed in the same era (1950s to 1980's).
This morning, I just walked by the now almost empty office building where I used to work over a decade ago. It was proposed for conversion a few years ago, but nothing has happened since. It is not that big, but very square and one side has no windows, so it may not be a great candidate for conversion.
