There is corruption in this industry partially because there are clearly too many. The money is huge and Some are desperate. The current penalties for fraud are pathetic. There needs to be a washout. Cash Penalties won't do it. Jail time will. Proper government oversight will . Currently TREB, and the OREA are covering corruption. 
This is an effort to cover their ass in the eyes of the public after the horse has left the barn.. The government needs to step in, collect proper market  data , not the marketing nonsense TREB puts out. Require realtors report data to keep the market transparent and accountable.  Anyone who fails to report in a timely fashion goes to jail AND loses all money related to shady transactions and loses their  licence for life.
