Another resource (albeit sometimes not a particularily genealogically helpful one) are old Canadian Naturalization records. An explanation of the Naturalization process can be found at the Government of Canada’s website. All newly naturalized citizens were listed in a report published by the Secretary of State, and also published in the Canada Gazette (the official newspaper of the Canadian Government).
Danylo Koszlak became a naturalized citizen on July 18, 1932. At the time, he was a labourer in Beausejour. His record was published October 15, 1932.
I have not yet found Passenger or Naturalization records for wife Annie Bruchanski.
