Hemson did their due diligence in choosing the comparisons. They certainly were not random. The Consumers Rd. location was chosen as it is very comparable to the Airport CC. Both are located by intersecting highways and are served by transit. The Consumers Rd. location, with taxes being equal, should be worth at least as much, as it is better served by transit and located in a denser area. Are there any reasons that you can think of that would place such a premium on the Mississauga location ?
As the chart shows on page 12, compare the land appreciation values for even south Mississauga to those in Toronto. Some people here use the excuse that all large cities face a flight of jobs/development to out lying regions. What differs in Toronto's case is that they pay more for land to do so.
The problem is that it defies normal market dynamics and signifies problems. In the proformas, it shows that building such an office in the city is not feasible. In Mississauga, despite paying far more for land and an additional 800,000 in development fees, a developer is can make a profit. Conversely in Toronto with cheaper land and development fees, such an office would be worth less (~4 million less) and not be profitable.
If water front condos in Barrie were more expensive than those in Toronto I would also say there is problem.
