As a general rule, only Canadian residents can divorce in Canada. If neither you nor your spouse lives in Canada, you cannot get a divorce under Canada’s Divorce Act. But you may be able to end your marriage under the Civil Marriage Act if you meet BOTH of the following criteria:
You married in Canada; and
You cannot undo your marriage in the country where you or your spouse lives because that country does not recognize your Canadian marriage.
To undo your marriage under the Civil Marriage Act, you would need to apply to a Superior Court in the province or territory where you married. A lawyer in that province or territory may be able to advise you on what you need to do. You may also be able to get information from a Superior Court or from the Department of Justice or Attorney General in the applicable province.
A process under the Civil Marriages Act only ends the marriage. You would need to resolve other issues such as child support and spousal support under the laws of the country where you live.
