The Canadian Coast Guard will keep prioritizing the task of ensuring that owners take responsibility for their vessels and that the vessels are disposed of responsibly at the end of their life cycle.
With regard to your example, the vessel remediation fund will come into force shortly. If the damage is caused by oil pollution, the Coast Guard can also submit claims to the ship‑source oil pollution fund. The industry has contributed to this fund. The Coast Guard can submit claims to cover costs. The Canadian public doesn't pay for the Coast Guard's activities under these circumstances.
