Canvas notifications can be edited to your preference. It is important to note that each time you or your student begins new courses, course specific notification settings may override the selections you've made previously. If you find you're suddenly getting more (or less) email's than you expected, please check your settings again.
Select the circle at the top of your menu options, this may be a photo or your initials, then click Notifications.
Your notification settings page will give you a number of options. Click the icon for each section to see what options you have for each activity.
Below are three Canvas guides that give more details on student notifications, parent notifications, and what triggers a notification.
