2015 Challenge Trophy

The 2015 Challenge Trophy is the national championship for men's soccer clubs competing at division 4 and below in the Canadian soccer pyramid. It will be held in Calgary, Alberta from October 7–12, 2015.

Teams
Twelve teams were granted entry into the competition; one from each Canadian province, as well as one from the Northwest Territories. In addition, as the host province, Alberta is granted a second entry into the competition.

Teams are selected by their provincial soccer associations; most often qualifying by winning provincial leagues or cup championships such as the Ontario Cup.

Group stage
The twelve teams in the competition are divided into four groups of three teams each, which then play a single-game round-robin format. The top two teams from each group advance to the knockout round, while the third-placed team enters a relegation tournament.

Classification tournament
Third-placed teams from the group stage are entered into the classification tournament to determine overall rankings at the end of the tournament.

Knockout Round
Teams placed first and second from each group in the group stage advance to the knockout round. All teams play three matches, as teams that lose in the knockout round still advance to face other losing teams to determine final classifications for 3rd through 8th place.
