The religious section of the February 15, 1930 Toronto Globe contained this advertisement:
O.D. Cardey did not stay in Toronto long. He was listed in the 1931 city directory (as “O. D. Cardy”), but was not listed in 1932.
A Google search for Rev. Cardey didn’t turn up anything other than this link. Apparently, Rev. Cardey was a Seventh-Day Adventist but was reluctant to admit that fact up front. The Seventh-Day Adventists observe Saturday as the Sabbath, not Sunday.
I wonder whether there actually was a packed house for this service?
