The Hon. Stockwell Day, Minister of Public Safety and the Honourable Lawrence Cannon, Minister of Transport, Infrastructure and Communities, announced there will be increased security at all Canadian airports.

Individuals in the United Kingdom were allegedly intent on committing acts of terrorism using explosives on flights destined to North America.

"We have been in contact with the United States Homeland Security Secretary, Michael Chertoff, and United Kingdom Home Office Secretary, John Reid, to discuss the heightened security measures that are being put in place,” said Minister Day. “Our officials are working closely with officials in the United Kingdom, the United States, and other allies to protect the safety and security of Canadians. We commend the United Kingdom on disrupting this significant terrorist threat."

"In light of these events in the United Kingdom, the Government of Canada has implemented aviation security measures to help ensure the ongoing security of the travelling public," said Minister Cannon.

The following security measures are in place until further notice: Effective immediately and for all flights to and from the United Kingdom and the United States, liquids or gels in containers of any size are not permitted to be brought onboard by passengers; this includes liquids or gels in carry-on baggage.

For all flights, including Canadian domestic flights, liquids or gels in containers of any size are not permitted to be brought onboard by passengers; this includes liquids or gels in carry-on baggage.

Liquids or gels in containers of any size include: all beverages, shampoo, suntan lotion, creams, toothpaste, hair gel, and other items of similar consistency. Passengers may bring aboard baby formula, breast milk, or juice if a baby or small child is travelling.

Prescription medicine with a name that matches the passenger's ticket, insulin and essential other non-prescription medicines are allowed. Passengers should pack liquids or gels in checked baggage. The Government of Canada advises all air travellers to keep these measures in mind when preparing for a flight, and to contact their carrier regarding any possible delays.

The Government Operations Centre says it is coordinating the response of federal departments and agencies, and will be communicating with provinces and territories as needed.

At the Canadian Aviation Security Conference held in Ottawa in March, aviation experts, including Robert Milton, CEO of ACE Aviation Holdings, called for tighter restrictions on carry-on luggage which would speed flow of passengers. He said that while some countries, such as Australlia, have already restricted carry-on luggage to one item, it is considered a competitive issue and many airlines have been reluctant to tighten their policy.
