"In the event we were to encounter Modern Slavery practices in our supply chain caused or contributed to by us, we will take action to cease and prevent our contribution to the Modern Slavery practices. We will also provide for, and, or cooperate in remedying any actual impact.

Should we encounter Modern Slavery practices in our supply chain, we will use our leverage to influence the entity responsible for the Modern Slavery to take action and consider whether we should provide for, and, or cooperate in remedying any actual impact. If we are unable to exert the appropriate influence to have the entity to cease the Modern Slavery practices, we will consider terminating the business relationship. We will inform any victims that are identified within our supply chain of the remediation channels available to them and we will ensure that remediation is conducted confidentiality to protect any victim's privacy. We will also follow up once the remediation is completed to ensure that it has been effective, and the Modern Slavery has not re-occurred." (p. 12)

From this, I understood that "consider terminating the business relationship" refers to cancelling contracts, "we will use our leverage to influence the entity responsible for the Modern Slavery to take action and consider whether we should provide for, and, or cooperate in remedying any actual impact" and refers to supporting the supplier to respond to instances of modern slavery (corrective action plan) and "informing victims of remediation channels, ensuring confidentiality of the remediation to protect any victim's privacy and following up to ensure the remediation has been effective" refers to worker remediation.

IMPORTANT: 
The methodology said: If the company supports the supplier to respond to instances of modern slavery, please select the “Corrective action plan” value. - but I am not sure if I chose it correctly, as there is no mention of CAP.
I am also not sure if the remedy is specified enough to be considered worker remediation.
