What does it mean that sin has been canceled?

To say that sin has been canceled is to assert that the debt of sin, which believers owed to God, has been fully paid by the blood of Jesus Christ. In Hebrews 9 and 10, the term 'canceled' emphasizes that the actual guilt of sin is removed, allowing for reconciliation with God. This does not imply that sin never occurred, but rather that the consequence of sin—separation from God—is erased for those who are in Christ. The idea is akin to receiving a receipt stamped 'paid in full'; there is no outstanding debt remaining to be settled.
