Hi Jeremy,
I thought that it might be possible to host the HTML files right inside of your course Canvas files by simply uploading and unzipping your export folder but it doesn't work very well. So, it looks like you would need to host these on a web server. I was able to get this to work by placing the unzipped folder in my public Dropbox folder. However the player was a little buggy.
Because of this, I'd suggest you export it to a PowerPoint (pptx/ppt) or even a pdf file. Then you can upload these to Canvas and link to them anywhere in your course using the Rich Text Editor. What's nice about this is that the automatic document viewer/preview feature will render these in Canvas and your students can also use the link to download them.
Another option would be to use a service like Slideshare to upload them then you could embed them into Canvas.
The good news is that it is doable, just pick an option and see how it works for your students.
