As far as I know, you can sort and filter discussion postings, but cannot reorder them.
I did find some related feature ideas currently open for voting that you might be interested in:https://community.canvaslms.com/ideas/11924-discussions-today-post-date
If you would like to submit your idea as a feature request you can learn more at How do I create a new feature idea in the Canvas Community?
Sometimes when I've been asked this question, people are talking about the Discussions area, so I wanted to cover that option, just in case. The discussions automatically sort themselves based on most recent activity. If you want them to appear in a fixed order, you can drag discussions to the Pinned section on top. Then they'll stop moving around.
What is the difference between pinned and unpinned?

@dmiller41 , pinned discussions will stay in the order you want them to stay in on the discussions page. Unpinned will be organized by last time someone posted to the discussion. See the following guide for more information - https://community.canvaslms.com/docs/DOC-13346-4152808001
Hope this helps!
Of course Canvas will not let us sort discussion posts by date. I mean to allow us as educators to be able to do that would only provide us with the tools we need to make our job easier. <sigh yet again at the lack of features that are available on all other online learning platforms>
This is still not fixed? It is incredibly inconvenient and counter intuitive. Sortable discussions and groupable discussions are both immeasurably easier than this. It make it harder for those of us who plan ahead!
