Summary • Difficult but not impossible• Requires careful planning and execution• Special problems give rise to market
opportunities for Ontario businesses• Possible opportunity to supply services to
neighbouring Great Lakes states• There are no insurmountable problems
that are not opportunities.• “Yes we can!”
