As per the information you have, CSIS has completed its involvement, if any. As regards, CBSA, can you confirm that Activity 1 is the most recent one? and what os the date of the activity 3, received by CBSA.
Usually it takes an average of 120 days as per the security screening manual. Also, once the report from CBSA is sent, it will be revised by IRCC and updated accordingly, which may take a few days.
Once you have the dates you can compute when the report was sent to IRCC.
Thanks for your reply. the dates are blanked out in the activity section. Activity 1 is the most recent which has a status of favourable. @legalfalcon
