There is currently no ban on campfires. However, there is still a ban on any fire larger than a campfire. According to regulations, a campfire is an “open fire that burns piled material no larger than 0.5 m in height and 0.5 m in width and is used by any person for recreational purpose, or by a first nation for a ceremonial purpose.”
For those who are not yet fully metric, 0.5 metres is roughly 19 inches.
