I had REMAX Ontario Atlantic review all the stats from the OREB for the whole of 2010.
Results are:
market share: Royal Lepage 31.97% (they have 32.5% of the Realtors)
market share KW 15.2 % (they have 18.2% of the Realtors)
market share REMAX 19.45% (we have 13.86% of the Realtors)
Summary: # units per Realtor in 2010
REMAX 17.62
Royal Lepage 12.37
KW 10.3
*note the average for all companies combined is 12.6 units per Realtor
Or, REMAX agents are 72% more productive than KW Realtors, and 42.44 % more productive than Royal LePage Realtors.
