The Government of Canada published the Canada-Ukraine authorization of emergency travel (CUAET) exemption requirements of the temporary public policy for Ukrainian nationals, signed by Immigration Minister Sean Fraser on March 16, 2022. The public policy that took effect on March 17, 2022, is set to expire on March 31, 2023, and may be revoked at any time without any notice. So far, 117,606 Ukrainians have arrived in Canada through the CUAET. As of November 15, 2022, IRCC received 689,854 applications and approved 420,196 applications from Ukrainian nationals under the CUAET. Some observers think the IRCC may extend this public policy as the war in Ukraine will not stop until March 31, 2023.
