Goodale said his officials assured him they can get the job done, despite the ambitious timeline.
Goodale’s portfolio includes CSIS, which does much of the screening work, as well as the Canada Border Services Agency and the RCMP.
從上面看,安檢至少有三個機構:RCMP, CSIS, CBSA。因為不同部門的工作不會重疊,可以推論安檢至少有三道關卡。
現在不見得是 有些人三關完全沒查就過來了。政府管事的也有大腦嘛。
比較可能的情況是,先進行比較快速的安檢,比如面談,簡單的背景調查,兩道關卡過了,來了之後再更仔細地查完第三道,全過了再放進社會。
來了以後才有問題的人該怎麼辦?如果他們還在軍營裡或許就直接空投回去了

亂猜的。
