On April 27, the Canadian Immigration Department issued an announcement. This announcement changed the rules for renewing the Maple Leaf Card. Originally, the new card was required to be collected in person. Now, the new card will be mailed to the address in Canada filled in when applying. The announcement stated that as of April 30, 90% of the naturalization applicants who do not require further investigation do not need to receive the card in person. Instead, the Immigration Department directly mails the new card. In addition, to facilitate naturalization applicants, the Immigration Department will also increase the proportion of further investigations on naturalization applicants from the original 2.5% to 5%. The announcement pointed out that this large-scale mailing of new Maple Leaf cards is a trial plan. After a one-year trial, an evaluation will be carried out to determine whether the approach is sustainable. For some people who need to return to their place of origin due to urgent matters, the emergency application for Maple Leaf Card replacement is included in this trial plan. There are applicants who do not need to be investigated. 90% of this group of people do not need to collect the card in person, but use the mail method. Only 10% of applicants will be required to collect the card in person. In addition, the order in which emergency applications are processed remains in accordance with the previous "first come, first reviewed" principle and has not been changed. For those applicants who must be investigated, the possible investigation results are also clearly stated in the announcement. In the first step, if after the investigation is completed, the results show that no immigration officer determines that the applicant is not eligible for permanent residence, then under such conditions, the Immigration Department will still issue a new card for a period of 5 years. At this time, the new card will be delivered by mail to the address filled in by the applicant, and the delivery is completed.
