I just got the email from Ottawa. The content of email is as follows:
"Please be informed that online applicants have the option to submit their passport to a Canadian immigration office abroad. If you choose to submit your passport to a Canadian mission abroad, please contact that office for information regarding processing times for visa printing. For a list of visa offices outside Canada, please consult: http://www.cic.gc.ca/english/information/offices/apply-where.asp"
