I received 3 from
donotreply@cic.gc.ca with "Your application has been updated." message.
The first was "Confirmation of Online Application Transmission" on July 15
The second, "Acknowledgement of receipt - Application for permanent residence" on July 15
The last one, "How to find a job in Canada" on Aug 14
Since then, nothing... Only knew about IP2 because I noticed that the "background check" text changed.
