I found POI's family still living in NE Calgary in 1974 (Ancestry electoral lists) They lived around 84th avenue and 52nd street in the SaddleRidge Community.

Prior to moving to the NE, they lived near downtown in the southwest and Western Canada high school would have been his school.
Perhaps they bought the Airdrie acreage, and didn't move until POI finished high school? There were no high schools in the NE at that time, so POI would have had to travel to the NW, he could have attended Sir Winston Churchill or Crescent Heights high school if he didn't travel downtown to Western Canada.
