I just got off the phone with a lawyer in Yellowknife. She regaled me with tales of golfing North of the 60th Parallel.
First thing to know: there is no grass, or at least only very little. The golf course is mostly rock and sand.
Second crucial point: Bring your own square of Astroturf. Golfers carry around their own piece for teeing off.
Third critical point: Watch out for the bears! And bring heavy duty bug repellant.
And what’s even more fun, there is an all night tournament in the summer called the Canadian North Midnight Classic. I recommend you listen to the CBC 1968 archive coverage of the tournament that year.
For golf tourism I think the Yellowknife Golf Club is not to be missed!
