Ontario Birth Certificate, 1920 and Later, for Citizenship by Descent (ServiceOntario)
For Ontario births from about 1920 onward, certified copies of the birth registration come from ServiceOntario, the Office of the Registrar General. For a deceased person, copies are issued to next of kin, which includes grandchildren.
This is the Canadian-side record for one ancestor. Citizenship by descent needs a record for every generation in your line, from you back to that ancestor.
