I would like to provide the rationale for it.
The convention provides for access to supplemental compensation from member countries to the convention. Wording in the bill references the minister's request for supplemental funds, not to the amount established when Canada ratifies the convention, but to the liability limit of the operator, which is also $1 billion. While this is not an issue today, because both numbers are the same today, for example, $1 billion, should the government decide to decrease the liability of the operator in the future, the minister's request for supplemental compensation will be inconsistent with the policy.
