2015 Challenge Trophy

The 2015 Canada Soccer National Championships (officially the Sport Chek National Championships for sponsorship reasons) was the 93rd staging of Canada Soccer's amateur football club competition. London Marconi won the Challenge Trophy after they beat Edmonton Scottish in the Canadian Final at the Calgary Soccer Centre in Calgary on 12 October 2015.

Twelve teams qualified to the final week of the 2015 National Championships in Calgary. In the Semifinals, London Marconi beat EDC FC Burnaby while Edmonton Scottish beat Edmonton Green & Gold.

On the road to the National Championships, London Marconi beat Mississauga Portofino in the 2015 Ontario Cup Final.

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.

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.

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

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.
