where do I mention all westerners are corrupt? What I mentioned was when there is a westerners hand in corruption not when all westerners hand? Read properly before commenting.

They were milking the Qatari govt, and everyone turned a blind eye to it. Someone must have notified the authorities resulting in the Canadian govt directly handling the case over riding the management.

IF it was just a case of some small overpayment would the Canadian govt step in?
