I'm in Europe, and we don't use Canvas (at least, I've never heard of it). However, we have similar diseases. In my particular school, it's a massive SharePoint site plus ever more stuff in Teams. Plus Moodle, plus other services.

The MS services have not improved teaching at all. What they do, is fragment communications, and add ever more places people have to look, in hopes of finding things.

But the administration loves them. "The bureaucracy is expanding, to meet the expanding needs of the bureaucracy."
