Canvas (Quercus) Mobile Apps
Quercus is available as a mobile application by searching your device’s app store for “Canvas”.
The “Canvas by Instructure” mobile app allows instructors and students to conveniently access their course content, announcements, participate in discussions, groups, and other course related items on a mobile device.
The “Canvas Teacher” mobile app allows instructors and course staff to access course content and grade items on a table device (for example using a stylus pen to annotate grading) if you prefer.
You can learn more about these mobile applications in the Canvas Mobile Guides.
The Canvas app should not be used for any high-stakes activities such as submitting assignments or quizzes—important tasks and assessments should be completed on a desktop or laptop computer instead.
Troubleshooting Issues: The Canvas by Instructure and Canvas Teacher mobile apps are developed by Instructure, Inc., not the University of Toronto. Please be aware that these mobile apps have limited functionality, and the service through these apps are provided “as-is”. For a more complete experience access your courses using the desktop version.
Most issues can be resolved by uninstalling and reinstalling the app from your mobile device. Additional troubleshooting and questions may have to be directed to your cellular network provider and device manufacturer.
Note: The Canvas by Instructure app should be used only for coauthoring or editing Office 365 documents. The app should not be used to upload Office 365 files for submission to an assignment. To upload O365 files, use a desktop or laptop computer instead.
