Hi there,
I found a small family tree that shows the following.
Antonio Raposo
born 19 Dec 1927 Portugal
Died 11 July 1986 Toronto
Wife Maria Medeiros
Died 18 May 2010
Her obit was in the Kitchener newspaper.
The tree only shows a daughter but Maria's obit showed three kids.
The 1972 Voter's List for Toronto shows a Antonio Raposo living at 231 Markham Street and his occupation is listed as a sod labourer.
Don't know if this is your family.
I searched under family trees here on Ancestry.
Good luck,
Elaine
