That's why they are asking for passport pages. Even if you don't have a stamp for exiting the country, there might be a stamp from the other country where you travelled to. They might be able to make a determination based on that.Is this for real? CBSA has only started tracking exits since last year? So how can they be 100% sure the days you reported on your application where indeed correct ? Passports don’t get stamped upon exiting Canada either so no wonder why they take their sweet time to update physical present etc
The first batch of citizenship applicants who will be free from this requirement would be citizenship applicants after June 2025. Their eligibility period start date would fall after June 2020 and CBSA will have all the exit records from the country.
