Brian D. Johnson of Maclean's wrote, "This story of a woman’s quiet descent into postpartum depression at a summer cottage in Quebec is...'a perfect marriage of character and landscape.' And as a mediation on dappled lake light and addled psychology, it’s beautifully composed, both austere and lyrical. However, I found it slow, morally schematic and dramatically slack."[3]
The film was selected as one of Canada's Top Ten Films for 2008.[4]Damon D’Oliveira, a member of the Toronto International Film Festival Group which compiled the list, said, "The beauty of Rodrigue Jean's Lost Song is in its simplicity. He has crafted a spare and uncompromising film – rife with humanity – about first-time parents grappling with the mounting pressures of caring for a newborn. Gracefully understated performances creep up and deliver a gut punch at the film's unsettling climax."[5]
