Looks like Boundary Bay is starting to charge a $25 "landing and service fee", waved if buying some (expensive) fuel. Starts in January of 2018. Oh well, just go to delta airpark, its less than 2 miles away and has cheaper fuel, and no flight schools plugging up the circuit.
Totally possible other airports are jumping on the bandwagon as well.
