An army mother whose son committed suicide after his third tour in Afghanistan said her son did not get the help he needed in time.

coroner's report found 35-year-old Stéphane Legendre killed himself by overdosing on acetaminophen, a month after complaining that he had not been able to see a psychologist or psychiatrist.

Legendre returned early from Afghanistan in 2009 because his father was dying. He was diagnosed with depression a month later.

Legendre's mother, Camille Martel, said staff at the Valcartier Health Centre should have known her son was in trouble.

The centre classified Legendre as a "priority" three weeks after he complained that he had not yet received help.

The coroner's report recommended the health centre re-evaluate the wait times soldiers face before getting access to psychological help.
