With all due respect, but your own link disproves your claim:
CBSA (Canada) and CBP (US) collect data at the
land border of non-US/CA citizens to be able to track exits.
It is however incorrect that Canada collects exit data of air and sea travel. In fact
the very link you share says that the government doesn't do this yet but intends to do it.
Also, I ordered my CBSA record not too long ago and
it does not contain my departures by plane. Only my departures when crossing the land border to the US.
The United States collect data on flights leaving US aiports. But Canada does not collect data on flights leaving Canada.
Furthermore, the person I was referring to is a US citizen. And, again
by the very link you share, for Canadian an American citizens, not even exit data is exchanged between the two countries. So whenever a US citizen crosses the border to the United States, Canada has no way of knowing that he in fact left Canada, because the US does not forward the data to Canada.
Again, please read the link you shared. It says exactly that:
- Currently, air departures from Canada are not tracked but they want to implement it
- Currently, entries by land are not forwarded to the other country if a Canadian or US citizen is affected. But they want to implement that in the future.
Also, of course you should not lie in your application. But no one was talking about lying in their application. In fact, the person I was referring to shared the comprehensive explanation that he will attach to his application.
