Preventative measures by regulatory and response organizations for marine traffic:
- Vessels subject to International Maritime Operations requirements, Canada Shipping Act and other federal legislation when in Canadian Waters
- Vessels must have arrangement with WCMRC for spill response before entering Canadian waters
- In addition to Trans Mountain’s screening and inspection, the vessel's flag state, vessel charter and insurers conduct inspections before contracting with any ship
- Port State Control program run by Transport Canada. Includes higher inspection frequency for tankers (first visit, or once per year) and sharing inspection reports under international agreement (Paris Memorandum of Understanding (MOU) and Tokyo MOU).
- Vessels travel well-established traffic lanes managed by US and Canada Coast Guards under scrutiny of marine communication and traffic services from both organizations
- Port Metro Vancouver regulations and oversight ensure safe conduct of shipping within Vancouver Harbour including passage through First and Second Narrows
- WCMRC maintains spill response capability for the Port and the coastal waters of BC
- Loaded vessels have a second pilot on board
