GRAVENHURST, ON – A stubborn grass fire took nearly six hours to put out at the Muskoka Airport.

Crews were brought in from Bracebridge and Muskoka Lakes Fire Departments to assist Gravenhurst Fire Department with the blaze that broke out about 1:00pm yesterday.

Muskoka Lakes Fire crews were brought in as cover in Gravenhurst as Bracebridge and Gravenhurst crews battled windy conditions that saw both the primary asphalt and the secondary grass runway shut down for a time. 

Around 28 acres of grass was burned in the incident, which was deemed under control by around 4:00pm but crews were still working until 7:00pm dealing with hotspots.

There is no word on what caused the fire.
