The plane went down at about 6 a.m. ET near the runway of the airport in Cookshire-Eaton.
The pilot, the only person aboard, was extricated from the wreckage with hydraulic equipment.
The aircraft was described as a Quad City Challenger II ultralight.
It's not clear if the crash happened during takeoff or landing. However, Sgt. Hugo Lizotte, spokesman for the provincial police, said investigators are not sure what went wrong since the weather was clear.
The Transportation Safety Board is investigating.
