Overall, the fonts you'll find will be:
- Helvetica Neue
- Helvetica
- Arial
- Sans-Serif
Which font will be used depends upon what fonts are available to the user accessing the page (if Helvetica Neue is missing, but Helvetica, Arial, and Sans-Serif are present, then Helvetica will be used as it is higher on the list). Instructure does not provide a form of these fonts, so it is possible that any of these four fonts will be used if all the fonts before it are missing from the user's computer. It's highly unlikely that these will be missing as they are pretty much generic fonts provided by default to most OS', but that's no guarantee.
If, in the highly unlikely event that, all four of fonts are missing from the user's computer, then the font used will be dependent upon the default font of the OS. So, if the user has Symbols configured as the default font for the OS, then that is what will be used if the other four fonts are missing.
Note: These are the default fonts as set by Instructure. If your institution deploys custom CSS, these may not be the correct fonts. You should check with your Canvas administrators to confirm what fonts are correct for you.
