Qualifications for this response ... haven't done it ... don't have canvas, but I can Google! ;)
Please see:
https://community.canvaslms.com/docs/DOC-2713
at the bottom of that page, a note:
"Note: The export will be in IMSCC format, a common standard file that can be imported into any system that accepts Common Cartridge. You can also change the extension from .imscc to .zip and treat it as any other ZIP file."
Then the question becomes one of compatibility of exported Canvas common standard file with what Moodle can support.
