Yeah some of those vacancy rates are staggering. I know one building that was not mentioned that I believe is still 100% vacant ... the old Nexen building on 8 Ave & 7 St SW.
As an aside, I am pretty disappointed in Encana/Ovintiv. I would be surprised to hear that they still do occupy 840,000 sq ft of The Bow, and instead most of it is probably sub-let. Encana, before they split out Cenovus, was Canada's largest energy company and was supposed to compete with other global energy companies. The Bow was built for Encana and Cenovus in mind. Within a very short period of time, Cenovus moves over to Brookfield and Encana decides to change their name and move a large part of their operations to the U.S. There was very interesting article on all of this in a recent issue of Report on Business magazine. What a travesty.
