This week, amid some public outcry and criticism from the opposition, Public Safety Minister Vic Toews announced he’s postponing plans to record conversations at airports and border crossings.Somewhat belatedly – the equipment has already been installed – Mr. Toews backtracked and said that he’d ask the federal privacy commissioner to review the policy that, according to the Canada Border Services Agency’s website, was designed to enhance “border integrity, infrastructure and asset security and health and safety.”
