There is a birth in the Ontario database for Michael E. O'Malley who was born 4 May 1905 in Eldon, Victoria County, Ontario to Michael C. O'Malley and Mary E. Bassett.
I found this marriage at the Ontario Vital Statistics Project website (
http://www.rootsweb.ancestry.com/~onvsr/) in the Northumberland & Durham marriages:
16863-27 Ernest O'MALLEY, 22, clerk, Victoria Road, Frankford, s/o Michael O'MALLEY & Ann BASSETT, married Margaret MCAULEY, 19, Murray, same, d/o John MCAULEY & Catherine AMBROSE, witn: Ambrose MCAULEY of Trenton & Catharine O'MALLEY of Frankford, 8 Aug 1927 at Wooler (RC)
This is a transcript so it's possible that Michael's name was mistranscribed and the original says Emmet.
There is a birth in the Ontario births database for Mary Margaret McCauley who was born 3 Apr 1909 to John B. McCauley and Catherine Ambrose in Murray Twp, Northumberland County. John listed his address as Trenton.
If that's the correct marriage then here is the McCauley family on the 1911 census in Murray Twp (their surname was transcribed as McCailey):
