I still believe you could get the appointment for the attestation service in CGI Toronto. Please send an email to CGI for appointment.BLS had told me to self attest and email CGI to request for a waiver from attestation from CGI requirement and include copy of that email with the OCI application. When i email CGI they responded saying attestation from CGI is required and they are providing this service for via mail-in. I called BLS after that again. They then said follow CGI instructions
