The venerable TV game show “Jeopardy!” recently decided to exclude Canadians from competing on the show, even though host Alex Trebek is Canadian. Reuters reports that Trebek, who’s from Toronto, confirmed the move in an email sent out Monday by the show’s PR department. In it, Trebek said: “It is true that for the most recent ‘Jeopardy!’ contestant tryouts, Canadians were precluded from taking the online test, since the show must now comply with new rules set down by the Canadian government.”

The show did not specify which Canadian law sparked the concern, but Reuters notes that anti-spam rules passed in 2014 and a new digital privacy law adopted in 2015 could be among the culprits. “It was unclear whether either would prevent a Canadian from using ‘Jeopardy!’s’ online system for competing on the show,” the report notes.

The ban will apparently have a delayed effect, as Canadians who are already in the contestants pipeline will remain eligible.
