A B.C. Supreme Court judge has upheld more than $343,000 in cost-recovery fines that were handed to a forestry company for starting a wildfire in 2016.   A decision posted Monday says the wildfire near Nazko, in central B.C., burned about four square kilometres after escaping from a debris pile that a contractor set on fire at a Tolko Industries cut block.  The court heard that four so-called holdover fires were reported by Tolko to the BC Wildfire Service for starting active fires in the spring of 2016.  … Tolko initially won an appeal through the Forest Appeals Commission, which overturned the pay order saying the company was exempt under the Wildfire Regulation because it didn’t intend to start the fire and it found the blaze was a result of forestry activity.
