Cornelius worked for various farmers before he and his brother John invested in a farm in Killarney, Man. Eventually Cornelius took full ownership, and in 1970, turned the mixed farm into his dream: a successful dairy farm with 32 milk cows. He took care and pride in offering quality replacement bull calves to beef farmers. He sold the dairy in 1985, farming beef cattle and pigs until 1992. Cornelius and Elnora sold the farm and moved into town, where they enjoyed life together.
