Please plan to attend the Annual MASO Member/Business Meeting on Friday, September 14, 2018 at 3:13PM in Salon A at the Fairmont Royal York in Toronto, Canada.

The MASO Board is proud of the way it administers the Association finances.  Among the AAO constituents, MASO has one of the lowest rates for member dues.  MASO last adjusted dues in 2004 – 14 years ago.  The MASO Board is requesting that members approve a dues increase of $20 across all membership categories beginning in 2019.   Our financial status is favorable with healthy reserves in spite of inflationary pressures and a significant commitment to support the residents within our constituency.  The Board feels it needs to meet its fiduciary responsibly to keep MASO reserves strong, ready to meet future needs.

We ask that you attend the MASO/GLAO Annual Session.  Please go to and register!
