On a quiet farm in New Brunswick, a young woman sat with headphones pressed to her ears.
No tanks. No aircraft overhead. Just static — and beneath it, faint Morse code drifting in from the North Atlantic, sent by German submarines hunting Allied convoys.
One of those women was Elsa Lessard.
What was she listening for?
Born in Ottawa in 1922 into a Navy family, Elsa already knew Morse code. Her older brother had taught her when she was young.
In 1943, she enlisted in the Women's Royal Canadian Naval Service — the Wrens — and received specialized training for a job that very few Canadians even knew existed.
She became one of roughly 700 Canadian women known as “listeners.”
Their mission was to sit for hours, listening to and transcribing enemy radio traffic, letter by letter.
Elsa served at two secret stations: Leitrim, just south of Ottawa, and HMCS Coverdale, on farmland near Gunningsville, New Brunswick.
From the outside, Coverdale looked like an ordinary farm.
Inside, Canadian women were listening for an enemy thousands of kilometres away.
German U-boats used radio communications to report convoy sightings and coordinate their operations. The listeners had to pull those signals from the static, identify them, record them and help determine where the transmissions were coming from.
The information was then sent onward to Britain, where it could be combined with intelligence from other listening stations and fed into the wider effort to track German submarines.
Elsa did not break Enigma.
She caught the signals that made the rest possible.
The work was exhausting.
Eight-hour shifts. Day and night. Around the clock.
Elsa later remembered that the worst shift was the graveyard shift, around four in the morning.
And there was another burden: secrecy.
The Wrens were sworn to silence. They couldn't simply go home and tell their families what they had been doing all day.
Their families knew they were serving.
They didn't know that, behind closed doors, their daughters were listening to German communications connected to a deadly war being fought across the Atlantic.
After the war, Elsa spent years making sure Canadians remembered the women who had served.
In 2008, she received the Minister of Veterans Affairs Commendation.
She died in Ottawa on July 22, 2025, at the age of 103.
For years, Canadians knew almost nothing about the women behind those headphones.
But while German U-boats hunted Allied ships in the Atlantic, Elsa Lessard and hundreds of other Canadian women were quietly listening.
No battlefield.
No headlines.
Just headphones, static and the faint signals of an enemy.
Had you ever heard of Canada's wartime “listeners”?
