Over the days of competition, provinces and territories compete for the Western Canada Summer Games Trophy. At the conclusion of every sport in the Games, each province/territory is ranked according to a system outline in the sport’s technical package. Games Trophy Points are then awarded as noted below, with men and women ranked separately when they compete separately (i.e. softball). When men and women compete together in a sport, as in badminton mixed doubles, the points are combined.
Awarding of points towards Games Trophy
| 1st Place | = | 7 points |
| 2nd Place | = | 6 points |
| 3rd Place | = | 5 points |
| 4th Place | = | 4 points |
| 5th Place | = | 3 points |
| 6th Place | = | 2 points |
| 7th Place | = | 1 point |
When all sports are complete, the points for each province/territory are added together with the team having the highest point total being awarded the Western Canada Summer Games Trophy during the Games Closing Ceremony program.
