Hi Darla,
You can find Charles on the 1916 and then 1921 Canadian Census.
I found his brother, Rudolph, on the 1910 US census and then living as a widower with his brother in Canada - I believe his wife, Ellen, must have died in childbirth (son Clarence).
I think I may have found the death certificate of Fritz's oldest daughter, Millie, which would confirm the name of his wife as Augusta (no last name). I would also like to know more about Fritz and Augusta and be able to verify things. Have you found any more information on this family?
