Passengers travelling through Vancouver and Seattle-Tacoma Airports during the 2010 Winter Olympic Games will be checked against watch lists by the US and Canadian authorities.
The nearly-$1bn effort to secure the Winter Olympics is being deemed as one of the largest tests of North American security coordination for a major border event to prevent any kind of air, water or landborne attack.
The North American air defence system and the US Transportation Security Administration (TSA) will work towards the common goal of securing the area.
Canadian authorities will receive the TSA's help in securing two restricted flight zones over Vancouver and Whistler in British Columbia totalling 4,000 square miles.
US forces will watch for potential attacks and other threats in view of past terrorist activity at other Games venues.
State Department diplomatic security teams will protect athletes, while coastal surveillance and port security operations will watch vessels on or underwater.
