Stella,
Thank you for answering and giving the suggestions.
I posted in Saskatchewan because there was a hint that Alexander's brother may have moved there to set up his family and Alexander settled in Alberta.
I checked in the Redwater local historical society "Memories" and found the dates of immigration for both Alexander and Eva, but have failed to find any ship records.
I also located both graves of my grandparents, in a Redwater graveyard.
I have a copy of Alexander's naturalization document, but it only lists his place of birth.
I am uncertain of his brother'name, but as far as my father remembers it was Steve or Stephan (Stefan).
