The Ottawa HC joined the FAHL for the
1904–1905 season.
Ottawa vs. Dawson City In January 1905, the Ottawas were challenged by the
Dawson City Nuggets who travelled 4,000 miles (6,400 km) from the
Yukon to Ottawa for a best-of-three Cup challenge series. The Nuggets actually left Dawson City on December 19, 1904 and travelled on a month-long journey by dog sled and walking (Dawson to Whitehorse), ship (Skagway to Vancouver), and train (Whitehorse to Skagway, and Vancouver to Ottawa). Largely because of the long trip, they were no match for the Silver Seven. Ottawa defeated Dawson City in the first game by a score of 9–2. Numerous Stanley Cup records were then set in the second game, including
Frank McGee's 14 goals, and a 23–2 rout, the largest margin of victory for any challenge game or Stanley Cup Final game to date as of 2024.
Ottawa vs. Rat Portage Ottawa eventually won the 1905 FAHL title by finishing in first place with a 7–1 record. Then in March, the Rat Portage Thistles issued another challenge to the Ottawas. Although the Thistles crushed Ottawa in the first game, 9–3, Ottawa was without Frank McGee who did not play. However, McGee returned to lead the Ottawas to 4–2 and 5–4 victories in the second and third games to win the series. On the same day that the third game of the Thistles - Ottawa series was played, the
1905 CAHL season ended with the
Montreal Victorias winning the title. The Cup trustees accepted their challenge, however, the Montreal-Ottawa series was eventually cancelled because the trustees and the Victorias could not agree on either the game dates or the playoff series format. ==1905–06==
