Psi Factor: Chronicles of the Paranormal /ˈpsaɪ/ is a Canadian science fiction drama television series which was filmed in and around Toronto, Ontario, Canada, and aired 88 episodes over four seasons from 1996 to 2000.

team, including case managers Conner Doyle (Paul Miller) and Curtis Rollins (Maurice Dean Wint), senior data analyst Lindsay Donner (Nancy Anne Sakovich), physicist Peter Axon (Barclay Hope), Dr. Anton Hendricks (Colin Fox) as well as various other investigators that rotate with each new case.

After a limited role in the first season, Director of Operations Frank Elsinger (Nigel Bennett) becomes a more prominent presence and is often believed to have a hidden agenda, mostly by Matt Praeger who questions many of his decisions.

The team is in conflict at the end of the season, as Praeger learns Lindsay has betrayed him by leaking information, meant to expose Elsinger's questionable ethical activity.

In the two-part third-season finale, "Forever and a Day", Michael Kelley returns and informs the team of The Chairman, a mysterious figure who is believed to be evil and immortal and control a series of interlocking companies, including Veritec, Tessler Industries and the O.S.I.R.

The end of the third season marks the final appearances of many original characters, including Curtis Rollins, Frank Elsinger, Ray Donahue, Lennox Q. Cooper, and Michael Kelly.

With Elsinger apparently gone, Anton Hendricks has taken over the role of Director of Operations and very rarely takes part in the investigations over the course of the season.

In episode 18 of the season, "Regeneration", presumed dead Conner Doyle returns and reveals he was pulled out of the building before it exploded and then spent three years in Siberia where he was held prisoner in a research facility in order to study an alien parasite that he had contracted during the original mission.

He returns to aid the team in which they investigate "Project Regeneration", where a genetically altered female has the ability to heal herself, but with alien DNA that will take over and make her violent.

In 1997, the Committee for Skeptical Inquiry presented the Snuffed Candle Award to Dan Aykroyd (in absentia) for hosting Psi Factor and being a "long-time promoter ... of paranormal claims".

Following the awards, CSI fellow Joe Nickell wrote to Aykroyd asking for the research behind the "cases" presented on Psi Factor, particularly a claim that NASA scientists were "killed while investigating a meteor crash and giant eggs were found and incubated, yielding a flea the size of a hog".
