There is always room for improvement. It doesn't matter if it's process or technology or both.
There's always room for improvement and unfortunately there's a trust and verify...as well: You are supposed to use certain processes—it doesn't matter if it's contracting or procurement, but if somebody nefarious, for whatever reason, doesn't want to, there are sometimes ways to circumvent them.
As technology evolves, there are fewer and fewer ways...and there are more controls in place. I believe that CBSA has started putting in place controls and checks and balances that perhaps should have been there during the pandemic.
Yes, the controls, and the technology and processes, are improving as we learn from these events.
