The whole tracking system must be changed. Don't tell me they dont have passport control.
They don't have passport control.
If they want, they can implement it within seconds from airlines or from US border as ( its already linked US border). I can request my log in& out from my employer, gym, etc. how come they can't!
No, they can't.
For one thing, many people have multiple citizenships. This means that the passport you leave on may not be the one you arrive with.
For another, there are fake passports. Not all countries check electronically, so you could present a non-genuine passport to the airline and your real one when you land in the other country.
For another, not all border crossings are controlled. I've crossed at a location where there is no US control on the border (legally). At night, there's a phone box to call and check in on the way to Canada, but they have no real way to check if you do.
For another, the US-Canada border is the worlds largest unguarded border. There are buildings that straddle it. I went for a drive the other day, and there was a signpost where the US-Canada border was on a back road, three feet off the side of the road.
For another, there are plenty of places where one can cross on boat and there will be no record.
For another, planes are often given only a cursory search, and there are ways to get across the border without getting noticed.
For another, US and Canadian citizens do not get their information exchanged under the agreement due to privacy laws. I've crossed into the US many times, and Canada only has record of my return.
For another, there are many WHTI-acceptable travel documents that can be used to enter the US. I have entered on my passport, my passport card, my NEXUS card, and my enhanced driver license. Going the other way, I've used my CoPR and my BC D/L, as well as my PR card, US passport, my EID, and my Nexus. The US doesn't link PR cards (that information is not available to them, or useful as they use a SSN for linking everything). Canada can't link PR cards to US driver licenses, US passports (unless you use them for the PR visa). Even if they do have your passport number, as soon as you replace it, you get a new number, and thus won't have a 1:1 match in the system. They can approximate it using name, DOB, and country, but it's limited.
For another thing, the cross-border sharing agreement started in 2014, and someone might have returned a single day before that and there would be no record.
For another thing, people illegally cross the border regularly.
In other words,
no, it's not a simple matter, and anyone who thinks it is is being foolish. A gym or employer has a single database to manage. It's much, much easier.
Canada has absolutely no way to know how many days I have spent in Canada unless I tell them, given how many data sources and methods of crossing there are.
