In a best-of-five series, Vancouver emerged victorious, winning the championship in a thrilling manner that captured the attention of fans across the continent. The series began with a strong performance by the Millionaires, reflecting their successful season in the Pacific Coast Hockey Association (PCHA). The games were played at the newly built Vancouver Arena, which provided a fitting backdrop for the culmination of the 1914-1915 hockey season.

The Vancouver Millionaires were spearheaded by star players such as Frank Nighbor and Cyclone Taylor, both of whom played pivotal roles in scoring crucial goals and assisting throughout the series.

The final score in decisive games showcased a combination of skill, strategy, and determination, ultimately leading to Vancouver's crowning as champions.

This landmark victory not only elevated the status of the Millionaires within North American hockey but also marked a significant moment of unity across differing hockey leagues, paving the way for future inter-league competitions.
