Canvas' collaborations tab allows teachers and students to invite each other to edit shared documents, either through Google Docs or OneDrive. Collaborations can be used to facilitate group projects, create study guides, or brainstorm ideas.
Setting up a Collaboration
From the Collaborations tab of your course, select 'Start a New Collaboration'.
Select whether you want to use Google Docs or OneDrive to create the collaboration.
Each collaborator will need to have a Google account and authorize Canvas to access this account before they are able to collaborate.
