Built in the cold, for the cold.

Ptarmigan Dynamics is a Canadian aerospace company founded in 2026 in Kitchener-Waterloo, Ontario. We build small uncrewed aircraft, and the battery systems inside them, for long-endurance surveillance and monitoring in northern and cold-weather environments.

We started with a simple observation. Most small drones are designed for a mild afternoon. Take them to −20 °C and the battery gives up first: capacity falls, internal resistance climbs, and a “40-minute” aircraft is back on the ground in twenty. The people who most need persistent eyes in the sky, from Arctic sovereignty patrols and northern search and rescue to pipeline monitoring and remote research stations, are exactly the people the current market leaves short.

So we design from the battery outward. Our packs are built in-house for sub-zero operation, and our airframes carry only what the mission needs. Our first vehicle, Willow-1, is designed for 70 minutes of mission endurance at five kilograms, from −20 °C to +40 °C, packed into a single case that one person can carry.

We also care where the parts come from. Canada's north is a sovereignty question as much as an engineering one, and our supply chain reflects that: critical electronics and software from Canada and allied nations, battery packs built here, and the whole aircraft designed and assembled in Ontario.
