OTTAWA - Starting today, Canadians with Nexus cards will able to use them in faster security lines when flying to the United States from eight Canadian airports.

Those airports are in Halifax, Montreal, Ottawa, Toronto, Winnipeg, Calgary, Edmonton, and Vancouver.

Nexus is a 12-year-old joint venture of the Canadian and U.S. governments.

The program allows border guards to move people who are not considered a security risk through customs faster so travellers who appear to be high-risk can get a closer examination.

A Nexus card costs $50 and lasts five years.

To qualify, you must show you have no criminal record, and have never broken customs or immigration laws.

You also have to be interviewed by U.S. customs officials, and have the iris of your eyes scanned.
