Every wonder what information the CBSA kept about your border crossings.  I just ran into this nice article and sample FOSS (Field Operation Support System) report.  It showed the person’s crossing, the lane and time they entered Canada, the travel document presented, and whether the system was entered into the “FOSS live” system.  By and large it was boring record, but in the event of problems or in the case of a Canadian trying to carve out time on a L1 permit, it could be a very handy document to prove the person was outside of the USA.  It could also be very helpful for correcting a US I94 record.
