Change your course end date
All Canvas courses have an end date which is two years after the course start date. If you would like to prevent students from accessing your Canvas course before that date, in Canvas course settings you'll need to change the Section end date and the Course end date.
1. Log into your course in Canvas.
2. First, begin changing the Section Start date by clicking on Settings.
3. Click on the Sections tab.
4. Click on the name of your course's section.
5. Click Edit Section.
Depending on the width of your screen, the Edit Section button could be on the right side of your screen or could be below the names of all your students.
