Amendments to the Customs Act allow the Canadian Border Services Agency to collect entry-and-exit data on Canadian travellers and share it with Immigration and Citizenship Canada. For entries and exits by land, the regulations have been in force since June and will be implemented for air travel in June 2020.
The entry/exit program is part of a joint initiative with the U.S. called the Beyond the Border Action plan. For those in the process of citizenship, permanent residence or refugee applications, the information will allow the IRCC to monitor travel data to verify residency requirements, spot those who have overstayed visas, verify whether sponsors are residing in Canada and assist in fraud investigations.
