The only thread of credibility here lies in the fact that Stantec is a consultant. Flipping land that has been rezoned has happened a few times in Edmonton in the past but I would say that its success rate for finding a new buyer who wants to follow through with development is indeed rare -- usually only happens if their is financing trouble plaguing the site -- e.g. The Hat in the quarters; the Pendennis Hotel, also in the quarters. Sometimes, however, the motive is less obvious -- if the buy/flip master has other land in the vicinity, it can have the effect of raising the value of adjacent land without causing taxes to go up accordingly.
