Once a divorce is official, 31 days after the divorce order is entered, it is possible to obtain a Certificate of Divorce. The date will be shown on the first page of the divorce order.
Therefore, 32 days from the date the divorce order was made, a Certificate of Divorce may be applied for from the Registry where the divorce was filed using form F56. There is a fee of $40 for each certificate and the registry will need the file number associated with your divorce.
Alternately, parties to the divorce can make the written request as outlined on Ministry of Justice site, how to obtain a divorce certificate.
If the file number is unknown, the Central Registry of Divorce may be able to provide that information. They can be contacted by phone at (1)613-957-4519, Monday-Friday, 8am-4pm EST. They require the inquirer’s date of birth and the ex-spouse’s date of birth (if they do not have that, they need the date of marriage). The Central Registry can then provide file number and the name of registry where it is filed, for divorces filed and granted in Canada.
A Certificate of Divorce is not required as the court order of divorce is legally sufficient but it does still serve some purposes. It can be used to prove a divorce without revealing the terms of the divorce order or to quickly prove a marriage has been dissolved in case of pending re-marriage.
If a third party is requesting a divorce certificate the registry requires a copy of the divorce order, Form F56, and Form F17.
