I've also found a birth/baptism for another child: Sarah Florence Webb, born 9 Dec 1922 and baptised 8 Jun 1924 in Montréal (Anglican Saint Edward) to Bert Samuel Webb and Florence Haladay. On the same image is a birth/baptism for Dorothy Ruth Haladay, daughter of William Haladay and Cecilia Borgan. Both families are listed as living at the same address in Montreal.
I also found an entry in the same parish for the birth/baptism of Reginald David Webb. He was born 18 Nov 1924 and baptised 21 Dec 1924.
I also found a birth/baptism for Mary Joyce Webb who was born 5 Mar 1927 and baptised 8 May 1927. Also on the same image was the birth/baptism for William and Cecilia's daughter Clara Grace (born 2 Dec 1925 and baptised 8 May 1927).
The birth/baptism for Clara may have helped find another Haladay... the entry indicates William's full name is William Archibald Haladay. Is it possible the Archibald you mentioned in your opening post is William?
Hallelujah I found the marriage... Samuel Bertie Webb, electrician and Florence Haladay, daughter of Thomas Haladay and Elizabeth Harris were married 22 Apr 1919 in Montréal (Methodist Mountain Street). So this brings up another question... do you have the wrong maiden surname for Thomas' wife in your opening post or was Thomas married more than once or is the family on the 1911 census in Montreal the wrong family.
