| Case summary: |
The company Construction Demathieu & Bard (CBD) Inc., whose place of business is located at 170 Roland-Godard Boulevard in Saint-Jérôme, is a corporation that identifies its principal activities with the Quebec Enterprise Registrar as construction project management.
On November 28, 2024, Quebec’s Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs informed Environment and Climate Change Canada (ECCC) that a spill of water containing concrete, with elevated pH levels, had occurred two days earlier in the Lac des Deux-Montagnes. Following an investigation, our enforcement officers determined that this spill had occurred during restoration work on the Île-aux-Tourtes Bridge in Senneville.
Water with elevated levels of pH is deleterious to fish. Normally, water used during the installation of concrete structures should be treated to neutralize its pH before being deposited. However, our officers discovered that the treatment system was not functioning optimally, resulting in the deposit of rinse water with elevated pH levels of over 12 into the Lac des Deux-Montagnes. By depositing a deleterious substance into water frequented by fish, Construction Demathieu & Bard (CDB) Inc. contravened a prohibition set out in subsection 36(3) of the Fisheries Act.
Following an investigation by ECCC and work conducted with the Public Prosecution Service of Canada, Construction Demathieu & Bard (CDB) Inc. pleaded guilty to one count of depositing, discharging or permitting the deposit or discharge of a harmful substance.
