Investigators believe the man and a 14-year-old girl met via Facebook in August 2013 and developed a secretive sexual relationship.
In December the girl's parents discovered explicit chats between their daughter and Mangat and contacted police.
As result of the investigation, police believe there may be additional victims.
Alberta Law Enforcement Response Teams and Calgary police Service are asking other victims to come forward.
Satinderjit Mangat, also known as Sam Pat, is facing several charges, including invitation to sexual touching, and making and possessing child pornography.
