Immediately after capturing the ECAHA league title with a perfect record of 10-0-0, the Wanderers submitted a challenge to the Cup trustees, but before the Thistles could play the rematch they had to face the Brandon Wheat Kings in a best-of-three set to determine the champion of the Manitoba league. Kenora swept the series to retain the Cup.
Because the trustees had ruled that Kenora could not use Art Ross against the Wanderers, the Thistles imported Alf Smith and Harry Westwick from Ottawa. Although Smith scored in each game, Montreal's Ernie Russell led a winning attack with four goals in the first game and added a single in the second. Though Kenora won the second game, the Wanderers still took the total-goals series.
Both games were played in Winnipeg as a result of unsatisfactory rink conditions in Kenora.
