  OPPORTUNITY IN BEHAVIORAL TREATMENT

TORONTO -- October 10, 2012

GreeneStone Healthcare Corporation (OTCBB: GRST) (“GreeneStone” or “the
Company”) announces that it will expand its addiction treatment facilities
through a 'build & buy' growth strategy to take advantage of the green field
opportunity in Canada and the ever growing demand in the US in the
underserviced mental healthcare sector. GreeneStone aims to expand from its
current 36-bed treatment capacity up to 300 beds over the next twenty four
months. In the process, the company aims to expand its current revenue run
rate of $7 million plus to nearly $90 million. Management has currently
identified several potential acquisition opportunities in both the US and
Canada, several of which include underperforming operations in the US and
Canada and/or others that provide unique opportunity for profitable expansion.

GreeneStone is employing a 'build & buy' strategy in its growth plan. The
company has established a successful 'build' track record. GreeneStone Muskoka
was founded by converting a resort property into a first-class residential
addiction treatment facility. The Company’s outpatient and aftercare treatment
facility, GreeneStone Yorkville, successfully launched operations after the
company identified and secured the property and hired the clinical team. The
'buy' portion of the expansion strategy is intended to expand the company's
breadth of services, currently consisting of inpatient addiction treatment,
outpatient and aftercare service, and endoscopy procedures, along with eating
disorders for which facilities have been secured and are in the process of
being launched.

The company's revenue generating capacity for treatment beds is currently in
the range of $600 to $1000 per day per bed. Once GreeneStone's next two
clinics are opened, the company's bed capacity will expand to 118 from its
current 36-bed level, which would result in the company growing its revenues
from the current $7 million annualized run rate to over $35 million. The
revenue potential from expansion is considerable given the wide open playing
field in Canada, and North America. Recent M&A activity in the sector has
produced valuations for facilities in excess of $1,000,000 per bed, which
would result in significant valuation expansion potential for the company and
strong positioning in the current behavioral treatment sector.

“With awareness of mental health growing in North America, the healthcare
market is only beginning to wake up to the serious need for service and the
opportunity for companies to carve out an attractive niche in the sector.
Rapidly building out bed capacity and related services is essential to
establishing that positioning. Typical 300-500 bed players in this space have
revenue run rates in excess of $100 million from those operations. We are
highly active with our expansion strategy now and expect to be busy for quite
some time in order to reach what we consider to be the sweet spot in terms of
bed capacity starting at the 300 bed level,” commented Shawn Leon, CEO of
GreeneStone Healthcare Corp.

GreeneStone is a new company in the behavioral treatment sector in Canada, an
industry that has been well developed in the US but remains in its early
evolutionary stages in Canada. With increased interest from private equity
acquirers in recent history, the behavioral treatment sector has moved away
from the periphery. Acquirers like Bain Capital and Elements Behavioral have
clearly demonstrated the attractiveness of companies that can execute on the
operational side in this underserviced market.
