I have been able to successfully set up Class OneNote assignments using the Class Notebook plugin connection to Canvas, and it's able to pass through grades, however there appears to be a major flaw unless I'm missing something...
Namely that a student can still edit the OneNote page assignment after the date/time set in OneNote. I also tried updating the Assignment instance within Canvas to set an availability date. The student can still edit after I have graded the assignment also.
This could be a very powerful tool if there is a way to address the above, so I am hoping someone out there has a solution!
On a separate note - the grading is quite limited in that it cannot pick up our own lettered grading scheme in the OneNote display when the teacher is grading - however as long as I change the grading scheme in the Canvas instance, then Canvas does what it should with the grade I enter.
