It literally is... We don't have entry/exit controls.
Going way back in time, passports weren't a thing until World War 1.
We do have 'entry' controls; you must pass through customs at all borders.
However, we do not have exit controls.
You don't pass through Canada Customs (CBSA) when exiting the country.
But that isn't required as such, in order to know if people have exited.
Anyone boarding a plane or train has a ticket/boarding pass, and that data set can be used; for land borders Canada can easily exchange data on who was admitted from where.
Its a choice to collect the data..........
And its a separate choice to take enforcement action based on same.

Worth noting, the EU literally just activated full exit control as at April 10, 2026.
Japan, Singapore, China, and Australia all have exit controls.
The conspicuous list of countries that do NOT have exit controls as of today:
Canada, the United States, the U.K.
Hmmmm
I wonder what countries make extensive use of cheap, undocumented labourers in large numbers? Could there be a connection?
