Last February, Liam Toman went missing in the resort town of Mont-Tremblant, Quebec, while on a weekend ski trip with two friends. The 22 year-old from Whitby, Ontario, went out for dinner and drinks, after a day on the slopes, and never returned to his hotel room. Almost a year later, his family is still searching for clues, renewing calls for help from the public to find their son. The CBC's investigative programs The Fifth Estate and Enquête return to Mont-Tremblant with Toman's mother, Kathleen, to retrace Liam's final moments caught on surveillance footage before he vanished. We speak with investigative journalist and host of Enquête, Marie-Maude Denis, and his mother, Kathleen Toman.
