Ontario had same problem in the mid 1970's....they fixed it with speculator taxation....problem fixed overnight as a result.  Interesting back then to note the number of MPs that got caught with their pants down when the taxation came into play. Virtually everybody in Ontario that had any assets was playing the game and making easy $.  Sad that it took five years for Ontario to act given that it was an previous problem with a solution that had a proven track record for succeeding. Only the very stupid intentionally ignore history and repeat making the same mistake time after time after time.
