CBSA is not supposed to be able to seize an expired PR Card.I just provided my Canadian driver's licence and landed passport stamp,I also mentioned I'm here as a student,so isn't the above documents not mandatory?pr card was taken as it was expired and the official said to apply for new one
From ENF 27:
While applications for a new PRC may be filed at any time before the PRC expires, the existing PRC must be returned with the application, as stated in R59(1)(d). For example, applicants may have forgotten to return a previous PRC that is still valid at the time of applying for a new PRC and that has not been reported lost or stolen. As a matter of policy, IRCC requests that expired PRCs be submitted with the request for renewal. However, a new PRC will not be refused if the client does not return an expired PRC. IRCC does not intend to collect all expired PRCs from clients.
