Lac-Mégantic: This Is Not an Accident

Lac-Mégantic: This Is Not an Accident (French: Lac-Mégantic : ceci n’est pas un accident) is a Canadian documentary television series, directed by Philippe Falardeau and released in 2023. The series centres on the Lac-Mégantic rail disaster of 2013, profiling both the bureaucratic failures that allowed the disaster to happen and the regulatory inaction that has hampered efforts to prevent a similar tragedy from happening again.

The series premiered at the 2023 Canneseries festival, and was screened at the 2023 Hot Docs Canadian International Documentary Festival, in advance of its television premiere on May 2, 2023, on Vidéotron's Vrai streaming platform for documentaries.
