Wait for a few days. Do both the things in the new year; Registering on-line and sending the appl to BLS.
Use Purolator, they have tied up with BLS. That is what I used. If you use Canada Post, it will go in their regular mail and could cause delays.
Call BLS and they will do all the 3 credit card chargings for Purolator over the phone ( one for pick up and two for 2 separate deliveries) They will send you email confirmations with the link to the Purolator Label printout for sending your applications.
Send both the applications in one envelope. Just clip them separately and mark them with a Post-it label.
Fees will be OCI-- 425 .00 to Consulate General of India, Toronto.
Surrender - BLS INternational Services Canada Inc. 257.40 ( when you call, confirm this amount).
