Canada to Prosecute Crimes on the Moon

Of course - canada only has jurisdiction over canadians-

"Under the subheading Lunar Gateway, the Criminal Code amendment reads: "A Canadian crew member who, during a space flight, commits an act or omission outside Canada that if committed in Canada would constitute an indictable offense is deemed to have committed that act or omission in Canada."

This would include crimes en route to or on the Lunar Gateway station currently in the works to orbit the moon, and also "on the surface of the moon," the document states."
