No should about it - it is all about politics.

I am well aware of s. 33 - my undergrad degree specialized in constitutional law and at law school several of my profs were constitutional experts instrumental in the drafting of the Charter so I am quite aware of the option.  However in the real world I simply do not see any federal government taking such action.

The Liberals have several times stated clearly they will not use the that power as they will comply with court rulings.

The Conservatives under Harper had a number of opportunities to use it and never seriously considered it despite the right wingnut fringe in the party setting its hair on fire.

Furthermore invoking s. 33 would require Canada to reject its international obligations and withdraw from various international conventions and agreements on refugees.  That will not be happening.

Besides the number of refugees in this situation is a drop in the bucket in the over-all intake of immigrants.
