Yet another reason to avoid flying

From the Canada's Edmonton Journal:

Listening equipment 'will record conversations' at Canadian airports: CBSA
Airports and border crossings across Canada are being wired with high-definition cameras and microphones that can eavesdrop on travellers' conversations, according to the Canada Border Services Agency.

A CBSA statement said that audio-video monitoring and recording is already in place at unidentified CBSA sites at airports and border points of entry as part of an effort to enhance "border integrity, infrastructure and asset security and health and safety."

As part of the work, the agency is introducing audio-monitoring equipment as well.

"It is important to note that even though audio technology is installed, no audio is recorded at this time. It will become functional at a later date," CBSA spokesman Chris Kealey said in a written statement.

But whenever that occurs, the technology, "will record conversations," the agency said in a separate statement in response to questions from the Ottawa Citizen.

Nothing like giving away the 'secret'. If I was planning anything and needed to coordinate with other people, I would use a set of pre-arranged innocuous code words. Have not flown in a couple of years and do not miss it at all.
