I accidentally deleted an entire class of content in Canvas. Unfortunately, it wasn't just my modules, there were modules in there created my other members of my team.
You can try the Undelete option within Canvas.
If this doesn't work depending on how long it's been since you created the content and deleted it, you can always go to go into your test or beta environment and export the course from there and import it back into production.
