The new party's platform was written by three residents of the city (Richard Rigg, Herman Saltzman and Jacob Penner), and it has been estimated that nearly 20% of the SDPC's total membership lived in Winnipeg during the early 1910s.
The SPC had contributed to reformist Fred Dixon's defeat in this election, and was shunned by many in the city's trade union movement as such.
In the provincial election of 1914, the SDPC ran Arthur Beech and Herman Saltzman as candidate's for Winnipeg North's two ridings.
Rigg had defended the city's immigrant population in the past, and was elected despite strong SPC opposition.
This time, he was endorsed by reformist labourites and Liberal supporters of Wilfrid Laurier because of his opposition to conscription.
