Border Crossing

Does anyone know if the Canadians at the border crossing keep track of when you come into Canada? Is there a record of when each person entered Canada? If so, when did implement a computer that would keep track & when did they start entering this info? If they don't, how would they know it you'd been there 1 month or 6? This is important for pensions. I would like the answer to this question if anyone knows. Thx Tipppytoes

CBSA don't talk to other agencies, they can't share information except during a criminal investigation because of the Privacy Act.

Thanks
