The law says
IRPA s. 52(1)If a removal order has been enforced, the foreign national shall not return to Canada, unless authorized by an officer or in other prescribed circumstances.
Return to Canada
(2)If a removal order for which there is no right of appeal has been enforced and is subsequently set aside in a judicial review, the foreign national is entitled to return to Canada at the expense of the Minister.
Justice Laws is the authoritative version. If this copy and it ever differ, Justice Laws wins.
