Hi Bernadette,
I don't know if there are actual birth certificates for that location/time frame: Disraeli, 1897. But this appears to be your grandfather's baptismal record:
"Canada, Québec, registres paroissiaux catholiques, 1621-1979," database with images, FamilySearch (https://familysearch.org/ark:/61903/3:1:3QS7-8993-WX26 : accessed 16 July 2021), Disraeli > Sainte-Luce-de-Disraeli > Baptêmes, mariages, sépultures 1884, 1897 Baptism no. 61 > image 365 of 496; Archives Nationales du Quebec (National Archives of Quebec), Montreal.
It appears that he was baptized Joseph Henri Ovila on 12 Sep 1897, born 11 Sep 1897 (né hier - born yesterday) of the legitimate marriage of Pierre Chretien, farmer, and Delvina Liberge, of this parish.
