Sea-Tac would be hangars. They have them here. Old airport hangars with shackle rings in the concrete floors. Had them in place prior to Y2K. That was the event used to justify the building and conversion of a lot of these centers, and some of them are at airports. Bergstrom AFB (local) closed around that time, and it now has a dual purpose--sound stages (the Spy Kids movies were shot there), and FEMA buildings, at least one of which has the bedspace in a hangar. I remember the local news actually showed the insides of the hangars before New Years eve, 1999. Reporters were let into a hangar and they broadcast video of the shackle rings, to let the public know everything would be done to take care of rioters if the computers all failed. I'll look for that film someday...bound to have been uploaded to the web by now.

As far as Alaska being impractical, Siberia wasn't too out of the way for the Soviet political prisoners, was it? And who says they'll get the luxury of heat? Alaska's where the timber is, so if you have a divergent political outlook, you'll end up working in the logging industry. State politicians in Oregon already tried to pass life imprisonment in logging camps for "terrorist" acts like demonstrating:

(b) When a person is convicted of terrorism under this section, the court shall order that the person be confined for a minimum of 25 years without possibility of parole, release to post-prison supervision, release on work release or any form of temporary leave or employment at a forest or work camp....

Are you trying to say that this is a worldwide phenomenon? Last I looked, Canada was not part of the US.

Then look again. Waco, Texas, 2005, leaders of Canada, Mexico and the U.S. began the merging of the 3 countries:

On June 21, viewers of CNN's Lou Dobbs Tonight heard the alarming introduction to a segment of the program devoted to the future of the United States of America. "The Bush administration's open-borders policy and its decision to ignore the enforcement of this country's immigration laws is part of a broader agenda," Dobbs intoned. "President Bush signed a formal agreement that will end the United States as we know it, and he took the step without approval from either the U.S. Congress or the people of the United States."

Here's a link to the video clip:

There's lots of information on the web if you search "North American Union," "Security and Prosperity Partnership," "NAFTA superhighway," etc.

Europe was flooded with people of different cultures before they were duped into the European Union. The same is happening here. Only, this scenario has the potential to get pretty bloody. That's why the U.S. govt has built so many concentration camps. In England I think they're called "rest and relocation centres." lol
