How about we take a page from Australia's enlightened strategy to control and vet illegal migrants and establish our own "Manus Island" detention center to house them until their cases are heard.

Montreal is an island.  Let's set up a national facility there.  We could use the Big Owe  - it has restrooms and kitchens and is only used for the odd Impact game anyways.

Mr. Coderre could really demonstrate his hospitality to the newcomers and protect them from the "heartless" CBSA goons .  Sounds like a win-win to me.
