The Joint Rescue Coordination Centre extracted an injured hunter from the woods near Aylesford, N.S. in the Annapolis Valley.
RCMP Sgt. Alain LeBlanc said two men were hurt while preparing their tree stand for the approaching deer season.
"We received a call that the tree stand that they were in fell out of the tree and basically the two men fell to the ground and sustained moderate injuries," he said.
LeBlanc said one man in his mid-50s managed to drive to safety on an ATV.
The other man, in his late 60s, was more seriously hurt.
"It's a wooded area so I can confirm that EHS and the fire department [were] there with him so he is being cared for," said LeBlanc.
A cormorant helicopter landed near the accident site on Aylesford Mountain and airlifted the injured man to CFB Shearwater. He was then taken to QEII Health Sciences Centre in Halifax for treatment.
