Summary based on 1 source
In the spring of 1975, a young woman named Sylvie Ouimet disappeared from Montreal, Quebec, leaving behind a life and a family who have not heard from her since. At the time she went missing, around April 1st, Sylvie was 20 years old. She was living with her parents in Laval but was receiving care at the Albert-Prevost Institute in Montreal because she had been experiencing suicidal thoughts. The day she vanished, she walked away from the hospital, leaving all of her personal belongings and identification behind.

Sylvie was described as having a slender build, standing at 5 feet 4 inches tall and weighing around 124 pounds. She had brown hair and blue eyes. It is known that she had a burn mark on one of her forearms and a surgical scar behind her ear. When she was last seen, it is believed she was wearing a green blouse, light blue jeans, and brown shoes; another report mentioned she may have had on a red coat. Her departure from the institution without any of her possessions was an immediate cause for deep concern for her loved ones and the authorities.

The circumstances surrounding Sylvie Ouimet's disappearance have left her family with decades of unanswered questions. Her case is a poignant story of a vulnerable young woman who seemingly vanished without a trace while under medical care. The fact that she left without any personal items suggests she may not have had a plan and her state of mind at the time remains a critical factor in understanding her disappearance. Despite the passage of time, her case remains open, a lingering and painful mystery for those who knew her and for a community that has not forgotten.
