Defence Minister Rob Nicholson and Veteran Affairs Minister Julian Fantino are expected to announce just under $200 million dollars over five years to address the issue among members of the Canadian Forces.
The announcement, which will be made at the Halifax International Security Forum, comes just two days before the Auditor General is expected to release a report on mental health in the Forces.
Statistics from the military show that 128 members of the regular forces and 32 reservists have committed suicide in the past decade.
A Statistics Canada survey released earlier this year suggests nearly one in six full-time members of the Canadian Forces experienced symptoms of mental health or alcohol-related disorders over several months in 2013.
The same survey shows that one-third of Canadian soldiers worry that seeking mental health services would harm their career.
The survey was developed by Statistics Canada with the Department of National Defence. About 6,700 regular force members and 1,500 reservists were interviewed from April to August in 2013.
