How would I get information about my son's grandmother?

-I am looking for information about my son's grandmother (father's side). All I know is that my son's dad was born in Trenton Ontario in 1953. He does not know her name. (I do know his fathers name though) Is it possible for me to ask the government, or is there a record of births for that time. Looking for any information that can help me.Have you looked on his birth certificate, it should show both his fathers and his mothers names, including maiden name if they were married or not....I don't know about the birth certs in Canada, however they have used simular documentation/records to the UK...in the UK you get a short and a full certificate...the short one doesn't tell you parents names, but the full one does, by applying for a copy of your sons, father full birth cert it should tell you the information you need.
