The Government is cloning The Canoe Cops.
This would explain how Sven and Gustav have seemingly died multiple times but nobody has noticed their absence.
Professor Jackson is involved in the government cloning program.
He is certainly brilliant enough and highly placed enough to be involved with such a program. This would also explain why he introduced himself to Sven and Gustav as if meeting for the first time despite having met them before in The Monster of Phantom Lake - he knows they are clones and reacts as if they are meeting him for the first time to maintain the facade.
