Canada Uses The Personal Information Collected At The Canadian Borders On Immigration Applications. 

News Source:- Since February 2019, the Entry/Exit Program has allowed the Canadian border to collect basic traveller information and share it with Immigration, Refugees and Citizenship Canada (IRCC).

IRCC uses the information to verify residency requirements for applications for permanent residence, work permits, study permits, and Canadian citizenship applications. Some programs require applicants to be in Canada for a certain number of days. For example, in order to apply for citizenship, permanent residents need to have been physically present in Canada for 1,095 days out of the five years prior to the date of their application.

With the Entry/Exit Program, IRCC can inquire about traveller information from the Canadian Border Services Agency (CBSA) via the Global Case Management System (GCMS), which is the system IRCC uses to process immigration applications. Read More.
