I tried this before - and failed - so lets try again.
The idea is that in 1905, rather than two provinces, a single "Province of Buffalo" is created that covers all of Alberta and Saskatchewan.
The objective is to simply list the results of all general elections in said province. I will thus begin with the following IRL info
22 Lib - Alexander Rutherford
2 Con - R. B. Bennett
17 Lib - Walter Scott
8 Con - Frederick Haultain

From what I can tell, turnout, which may differ between the provinces [by, for example, 10%, or 15%, or such] does not radically differ [by, for example, 30%, or 40%] and thus, can be used as a rough guide for population share.
