Canada recently had a "controlled burn" that was made by an international association. They weren't trained on Canadian forests properly, now it's a huge wildfire.
Which was this? The Banff one [may 4] doesn't seem related to this, and if anything seems to defend the practice by example - 31 hectares burned, 28 of which were planned, and only three horse stables were damaged despite weather changing suddenly and spreading the fire.
