Real-Life Relative: Paul Gross's wife Martha Burns as Fraser's mom, Caroline in the final episode.
The song Huey and Duey write in "Mountie Sings The Blues" is "Two Houses", the title track of Paul Gross and David Keeley's first CD. 'Ride Forever' and '32 Down On The Robert Mackenzie' are other Paul Gross songs.
After playing Fraser, Paul Gross did a much darker Mountie portrayal in "Murder Most Likely", a docudrama based on the case of real-life RCMP officr Patrick Kelly, who was accused of pushing his wife off of a balcony to her death. Questions remain even now about Kelly's guilt, but it's known he was also involved in other Dirty Cop stuff during his stint as an undercover officer. He's even suspected of burning his own home down for the insurance money, though it was never proven.
"Mountie On The Bounty" originally was to center on the Edmund Fitzgerald, but Paul Gross opted for a fictional ship after talking to the families of the men who died.
Interestingly, Leslie Nielsen, who played Sgt.Buck Frobisher, was the son of a Mountie in real life. During his first appearance on the show, he took Paul Gross aside and told him that he was lacing his boots incorrectly and then proceeded to teach him the proper way for a Mountie to tie his shoes.
Whether this series has three or four seasons depends on your country. Some areas ran the last third of the series as a single third season while others split it into a third and fourth season.
The whole reason for the Ray switch was because David Marciano had already moved his family back to LA after the post-season 2 cancellation, and he didn't want to move everything back. The apartment sets had also already been struck, leading to Fraser living in the consulate.
Fraser's uniform is incorrect in the pilot movie and first episode or so because the producers had to get permission to use the accurate uniform. This is standard for any police series, police forces like to keep a close watch on costume uniforms and badges to make sure no one uses them for illicit purposes.
