After the 1906-07 season, Canada finally established individual professional teams and, soon after, leagues were formed drawing back many players to play for their home crowds. In addition, it was apparent that, while the league was talking about expanding to larger centres such as Toronto, Cleveland and Duluth, there were problems among the existing clubs. The Pittsburgh franchise was seeking a league closer to home to play in and the champion Houghton-Portage Lake club wasn't interested in another season.
The other teams were still making plans for another season in 1907-08. Canadian Soo re-signed Ambrose Degray, Hugh Lehman, Newsy Lalonde, Ed Shaefer and Jack Marks. However, on November 4, 1907, Michigan Soo pulled out of the league citing a lack of players and the IPHL folded. The Pittsburgh team would be dissolved and the WPHL was restarted.
I sincerely appreciate the research work, and the information being shared. It is important and interesting history.
