Akib my tracker says nothing now,its blank but it said earlier that "Passport received at High Commission of Canada, Singapore, , Pin:*****, Tel: on 24/05/2012 and is under processing."
I got an e-mail too but it says passport received by the local canadian embassy. I suggest you to check the e-mail again, I hope they mentioned embassy in dhaka cause all the applications follow this chart : VFS>Dhaka embassy>Singapore embassy (Through embassy courier service)>Dhaka embassy>VFS
As you submitted in sylhet. so you may need 1/2 days extra not sure bro but hopefully you'll hear something within a week most probably
