A coroner’s public inquiry into deadly collisions involving heavy trucks is set to begin Monday at the Montreal courthouse, examining a series of fatal crashes that have raised broader concerns about road safety.
The inquiry was ordered in October at the request of Quebec’s public security minister, following a devastating August 27, 2025 crash on Highway 30 in Boucherville involving a heavy truck and multiple vehicles. The collision killed a mother and her son. Another fatal crash under review occurred July 15, 2025, in Ange-Gardien.

Proceedings are scheduled to unfold over five weeks between March 30 and Nov. 13.
The inquiry will focus specifically on the deaths of Madeline J. Darby, who died in the July crash, and Tanya and Elliot Lalonde, who were killed in the Boucherville collision.
In addition to these cases, the coroner may examine other similar fatal incidents if deemed necessary to provide a fuller picture of the risks associated with heavy truck traffic.
The investigation aims to determine the causes and contributing factors behind the crashes, while also prompting a wider reflection on road safety involving heavy vehicles. Recommendations are expected at the conclusion of the process to help prevent similar tragedies in the future.
