I need help finding her online

This is one of my favorite pieces of media, and I was curious about the sources. I did some online research and found some 2017 records on Imgur—accessible only via an archiver: https://web.archive.org/web/20170906120303/http://imgur.com/a/a2HBQ I couldn't find anything older than that. People online call her "Claire" and him "Mysterycanadaamatur." However, I’d like to know their real names; having their surnames would help me dig deeper. I found a connection to Calgary, Canada; he spent time there and made more videos with a girl named Emily C. If you have any more information, please add it here.
