Here is a guide for how to view the Calendar iCal feed to subscribe to an external calendar as an instructor?
The Calendar iCal feed is located in the sidebar of your Calendar. You can import the iCal feed into any calendar app that accepts the iCal format, such as Google Calendar, Apple Calendar, Outlook, and Yahoo Calendar. You can also download the calendar feed as an ICS file. The calendar feed will contain events and assignments from all of your Canvas calendars.
Note: All future events, and past events within 30 days, are included when exporting a Canvas calendar to another calendar program.
