According to his attestation papers dated August 17, 1916 at Toronto Edward Lee was born August 1, 1898 in Mimico, Ontario. He listed his father James Thomas Lee, Mimico, as his next of kin. He indicated that he was a baker by trade and that he was a current member of the 12th York Rangers. He was 18 years of age and stood 5 feet 4 inches tall. He had brown eyes, black hair and a dark complexion. He was Presbyterian.
There is a note on his papers which states: "Actual age claimed June 10, 1918. Statutory Declaration (Rcd Record Office 8-6-18) shows date of Birth Aug 1, 1900".
The 1911 census indicates that he was born in August 1899. He was therefore probably only 17 years old when he enlisted. If the notation on his attestation papers is correct then he was only 16 years old.
In the 1921 Toronto City directory I see his father James T Lee listed as a railway inspector living on the north side of MacDonald Street, Mimico
