Upload a file to Files in Canvas - How do I upload a file to a course?
Adding a file to the Syllabus Page - for this one when you go to the syllabus page, click edit, then remove the current file (you can just delete it) and then add the new file using these directions - How do I insert course files into the Rich Content Editor using the Content Selector as an instructor?
