Go to the official Government of Ontario online certificate application website. This website allows individuals to apply for birth, marriage or death certificates. In the case of birth certificates, a guarantor, that is a person who can vouch for you, is needed if the applicant is over the age of 9. The guarantor must be a Canadian citizen that has known the applicant for over two years and must be a professional, such as a dentist, judge, lawyer, mayor, nurse, pharmacist, doctor or police officer.
Fill out the online certificate application for an Ontario birth certificate. You will need personal information about yourself such as city of birth and mother's maiden name, and information about the guarantor such as ther work address and daytime telephone number. This application process involves entering personal information so be sure to log off or clear the browser history if using a shared computer. When finished, hit "Send".
Print the application form and send it by mail to the Office of the Registrar General or print the application form and bring it to a Service Ontario location if you do not wish to send it online. The Government of Ontario guarantees that it will take no more than 15 days to receive the birth certificate by mail or applicants can get a refund.
