Hi @elena_popa - Yes; you should be able to do this just fine. You can create an assignment like you always do--graded or not, and create a rubric for it. For the rubric options, however, just select the checkbox for Remove points from rubric. But you can otherwise add criteria rows and rating columns as always. Here is a quick example I whipped up:

You can then head to SpeedGrader and place comments within the rubric, just like for a graded assignment AND give general comments in the bottom part of SpeedGrader.
The student can then head to GRADES and view the rubric and comments. You just have to remind them on what to click on to view everything; for example, the rubric directly from their view of GRADES is seen a couple of ways, including clicking on the icon circled below:

In the example above, the instructor clicked directly in the cells for the rubric to generate the colored bars underneath. You can see the comments within the rubric in the cell named COMMENTS.
So basically, this should be entirely possible within Canvas, Elena. Try it out in a sample class, if you can, and use your Student View to see.
Hope this helps.
