Note: There are easier ways to embed a Google Document, but I found that the other options caused problems: the document would be too small, would not update (or very slow to update), and/or it was hard to navigate. The steps below are more extensive, but the result was worth it.
Embedding A Google Document
1. Get the share link from the google doc
2. On Canvas Page, click to insert media
3. Paste the share link, but change the last part of the link CHANGE/edit?usp=sharingTO/preview?pli=1 *Note =this is what puts the document into preview mode and show up on the page correctly.
