One person has been fined $600 after an explosive gender reveal party near Fort McMurray sparked a wildfire.

The fire, which started in the Fort McMurray Forest Area on the afternoon on May 31, was ignited by a family that took to the woods to celebrate their soon-to-be new baby.

Wildfire officials are declining to provide further details on the exact location of the fire or the person charged but are warning Albertans about the unusual cause: an exploding target. 

The discs, often loaded with coloured powder, detonate when struck by a projectile, such as a bullet.

This is the third unintentional wildfire started
