In the following articles, Meyers is spelled Myers. (It's not my typo!)
The Gazette (Montreal) · Friday, November 23, 1923
The engagement is announced of Miss Madeleine Milcah Walker, daughter of the late Mr. and Mrs. James J. Walker, of Moncton N.B., to Mr. Leo Patrick Bradley, of Montreal, son of Mrs. Margaret Bradley of New York, formerly of St. John, N.B. The marriage will take place in Montreal on December 27. Miss Walker is spending the winter in town with her sister, Mrs. Charles Edward Myers, Mackay street.
The article describing their marriage, in the Gazette dated December 27, 1923, it mentions Madeleine's brother-in-law; and his name is written as C.E.P. Myers. Gertrude is referred to as Mrs. C.E.P. Myers.
I can find one mention of a Charles E. Patrick Myers in the papers, but nothing solid on the genealogy sites...
P.S. I realize you are only after Charles' death, but we need to dig around for anyone that may have an obituary/news event, with him mentioned in it, to really narrow down the where and when for him.
