Enabling Turnitin on a Canvas Assignment
Instructors can enable Turnitin on regular Canvas assignments – it is not a separate assignment tool as it is in Blackboard. Open the Submission Type menu and select External Tool, and then click Find.
From the list of External Tools, click the Turnitin tool and click Select.
