I recently sent the required police certificates by mail to IRCC for my permanent residence application, and they have been signed for. However, I forgot to include the request letter which has my application information. There is no way I can get replacement documents sent out with the request letter by the deadline, and I can't find a way to contact IRCC to let them know this is what has happened. I am worried that my application will be refused because of this silly mistake. Does anyone know if there is anything I can do to rectify the situation, please?
