If the guarantor is a Canadian citizen, do I still need to submit information to apply for qualification in Canada?

1) For citizens or permanent residents, the requirements and procedures for applying for spouse immigration are the same. Therefore, Canadian citizens applying for spouse reunion immigration also need to apply for qualification.

2) Application procedures.

Simple: Canadian citizens submit a guarantee application to Immigration Canada-if the guarantee application is passed, Immigration Canada will send the relevant materials to the embassy or consulate where the guarantor is located-the embassy or consulate will inform the guarantor to submit the application materials-the embassy or consulate will send a form to inform the guarantor to pass the medical examination and get a visa after preliminary examination.
