Due South/Recap/S3/E01 Burning Down the House

Fraser returns from a vacation in Canada to find that 1) someone is impersonating Ray, and 2) his apartment building has been burned down by a performance arsonist, whose calling card is to leave dozens of little toy ducks at the scene.

Tropes

 * Celebrity Paradox: Buck Frobisher's resemblance to "legendary Canadian actor Leslie Nielsen" is remarked upon. Fraser's comment that Nielsen had never won the Order of Canada was true when the episode aired, but no longer.
