Transporting Dangerous Goods for Commercial Purposes


Space for commercial vehicles is limited on board our ferries. In addition, specific areas are designated for the transportation of dangerous goods.

To facilitate boarding and ensure the safety and health of our passengers and employees, we issue the following recommendations:

  • Reserve your crossing, if possible.
  • Choose designated dangerous cargo sailings, if applicable.
  • Use the boarding lane reserved for vehicles transporting dangerous goods, if applicable.
  • Arrive early at the ferry terminal to allow sufficient time for STQ personnel to conduct the required inspections.

Please contact us if you have any questions about transporting dangerous goods.

Please note that for safety reasons, all of our ferries are designated no-smoking areas.


All carriers transporting a cargo of dangerous goods must also:

  • Display the class of goods transported and appropriate safety markings
  • Be in possession of the duly-completed shipping documentation

Commercial carriers are required to know and comply with the following laws and regulations at all times:

Any carrier that fails to comply with applicable laws and regulations may be denied boarding to the ferry.


In addition to the Special Travel Permit issued by Société de l'assurance automobile du Québec (SAAQ), all drivers of non-standard vehicles must obtain clearance from Société des traversiers du Québec (STQ) before travelling on an STQ ferry.

Maximum loads and dimensions vary depending on the vessel used. You must contact the ferry office for the crossing you plan to take to obtain clearance to transport dangerous goods, where applicable.

Please note that STQ or the captain of a vessel may delay or cancel boarding for non-standard vehicles without notice.
