use only CIC e-case system , do not use third party e-case tracker....
Read terms and security option of CIC ecase system.
2- Keep your identification number(s) confidential to make sure that others cannot view your application status.
I strongly recomended to use cic ecase https://services3.cic.gc.ca/ecas/authenticate.do?app=ecas
don't use some third party (unknown person) will send you the ecase process!!
CIC e-case system online and available 24/7 then why we need third party services for e-case? even they also will use the CIC e-case system only...
anyway it's depen on you guys!!! bu I don't believe in these 3rd parties tracking systems for security for my application.
