Done my first portion interview at YYZ airport with CBSA 2 days ago until now I have yet received the email. Maybe I would need to wait until I do CBP interview and they will issue me the final letter of Approval.I see the same with my application. Applied April 2024. Conditional approval - no notifications - i booked an available appointment.. Dont worry about emails, if you can book just book appointment. You will be able to see the interview letter in profile.
