I saw a family tree at Ancestry which indicated that Robert's brother Leslie emigrated to Canada in 1927. The passenger list indicates he, his wife and son were destined for Pierceville, Saskatchewan. I'm not sure whether that should be Pierceland or Preeceville as there isn't a Pierceville in Saskatchewan as far as I know. I wonder if Robert may have been joining his brother?
Not sure if the Homestead files found by vbain would be yours. Soldier grant doesn't seem to fit with the timeframe of your Robert's birth and the parcels of land are both located close to each other and probably belong to the same individual (just my impressions of course).
Definitely not. According to the Saskatchewan Homestead Index website, soldier grants were only given to veterans of WWI which this Robert obviously was too young to be. As well, the Dominion Lands Act was replaced in 1930 with the Natural Resources Transfer Act so it's unlikely he would have had been able to apply for a homestead before the new Act came into effect.
