If there's one industry left that's ripe for major disruption it's the residential real estate agent business. The commission is way too substantial for the effort involved. An average Toronto home worth $1,500,000 should take about 1 week to sell. Maybe 5-10 hrs of work for an agent. That does not justify $75k in commissions. Maybe $7500.  Keep in mind the lawyer will make about $2000.
