Using your application no track the shipment on Purolator - https://www.purolator.com/en/shipping/tracker
If you don't find an entry better go to BLS and pick it up.
I have tracked it there using the PIN provided when I initially sent my application to BLS. The latest update is that my application package was delivered to BLS. But now my OCI is ready and is in Toronto BLS office. I actually paid for both deliveries (to BLS and from BLS) but my OCI seems is there for the last two months... Is it even an option to go to BLS and ask my OCI?
