Ottawa's National Research Council is hiding one of the coolest — and coldest — scientific facilities in the country, and CBC's Stu Mills recently got an exclusive look inside.
What Is the Climatic Engineering Facility?
Tucked away at the NRC campus, the Climatic Engineering Facility (CEF) is a massive climate-controlled testing chamber capable of replicating virtually any weather condition found across Canada. We're talking blinding blizzards, sub-Arctic deep freezes, torrential rain, and yes — freezing rain, the bane of every Ottawa winter commuter.
But this isn't about weather forecasting. The facility's primary mission is aviation safety.
Why Freezing Rain and Planes Don't Mix
Ice accretion on aircraft is one of the most dangerous phenomena in aviation. When supercooled water droplets hit a plane's wings or fuselage, they freeze on contact — altering the aerodynamics in ways that can be catastrophic. Engineers need to understand exactly how different aircraft components respond to icing conditions before those planes ever carry passengers.
That's where the CEF comes in. Researchers can dial in precise combinations of temperature, humidity, wind speed, and precipitation type to recreate the exact conditions an aircraft might encounter over, say, a stormy approach into Ottawa Macdonald–Cartier International Airport in January.
Building Better, Safer Aircraft
The facility works closely with aerospace manufacturers and regulators to test everything from wing de-icing systems to engine intake designs. By simulating freezing rain in a controlled environment, engineers can identify failure points and iterate on solutions without ever leaving the ground — or putting a real crew at risk.
It's painstaking, methodical work, but the payoff is enormous. Every improvement to anti-icing technology tested in a facility like this translates directly into safer skies for the millions of Canadians who fly each year.
Ottawa's Role in Canadian Innovation
The NRC has been based in Ottawa since its founding in 1916, and the capital region remains a hub for some of Canada's most cutting-edge applied research. The CEF is a prime example of the kind of quiet, unglamorous science that doesn't make headlines often — but keeps the country running safely through some of the harshest winters on the planet.
For Ottawans who have scraped ice off their windshields at 6 a.m., the idea of a facility that manufactures freezing rain on purpose might sound a little masochistic. But for the scientists and engineers who work there, it's all in a day's work.

CBC's Stu Mills got a full tour of the facility — it's well worth a watch if you want to see the chambers in action and hear directly from the researchers who make the weather (so airlines don't have to worry about it).
